Full or Partial Removal? Engineered or Non-Engineered? What is best for YOU?

2011-03-25T14:14:00.000-07:00

   So, you have finally decided to take the plunge and dive-in head first into your swimming pool removal.   Suddenly, you are faced with a whole new set of questions. How will your pool removal be handled? Most cities allow a partial collapse and fill, where others require a full removal of all concrete and rebar and then backfilled under the supervision of a licensed Geotechnical soils engineer. There are many options that fall between these two ends of the spectrum and I will do my best to describe each techniques and the pros and cons of each.

The Partial Removal and Non-Engineered Fill (Sides Broken down)
    The process:
    This is the most common type of removal that we see. This technique involves punching holes in the bottom of the swimming pool, breaking the sides (bond beam) down 18"-36" from grade and then backfilling and compacting with no engineering oversight.
     Suitable future use:
    Most cities will consider the area of the former pool non-buildable (no additions or dwellings) but the area will be perfectly acceptable for landscaping, sheds, concrete, plants or trees.
     Advantages:
    The main advantage to this type of pool removal is cost savings and the speed at which it can be removed (2-5 days)
     Disadvantages:
    There are a few disadvantages to this technique. The main disadvantage is that it will be something you will have to disclose to future buyers of the property and could affect the value of your home becasue it is considered non-buildable. On the other hand, you should check with the city building depatment and see what the property setbacks are to see whether it is a buildable area in the first place.
    Another disadvantage is that if someday someone wanted to install a new swimming pool the old one would have to be dug up, broken out, recompacted and re-dug to the shape of the new pool.
    Also, if this technique is performed incorrectly you may have an increased chance of sinkage, swelling, or a lack of proper seepage. Refer to How to hire a contractor blog to make sure your contractor measures up.

Partial Removal and Engineered Fill
   The Process:
   This technique is the same as above except that the backfill would be monitored by an engineer technician who would perform density testing during backfill and then submit a senior engineer letter. This technique is typically only used when required by the city but if you are unsure of your contractors abilities it might be a good idea.
   Suitable future use:
   Most cities will consider the area of the former pool non-buildable (no additions or dwellings) but the area will be perfectly acceptable for landscaping, sheds, concrete, plants or trees.
   Advantages:
      The advantages to this type of pool removal is cost savings and the speed at which it can be removed (4-5 days). Another advantage would be that you have verification that the area has been properly compacted.
   Disadvantages:

Another disadvantage is that if someday someone wanted to install a new swimming pool the old one would have to be dug up, broken out, recompacted and re-dug to the shape of the new pool.

Full Removal with Non-Engineered backfill

The Process:

All concrete (Gunnite), fiberglass, liner, re-bar, etc. is removed from pool cavity and hauled off-site. The area is filled and compacted.

Suitable future use:

Most cities will consider the area of the former pool non-buildable (no additions or dwellings) but the area will be perfectly acceptable for landscaping, sheds, concrete, plants, trees or new swimming pool.

Advantages:

   When you sell your home your disclosure will state that the entire pool was removed which may have less impact than if you had performed a partial removal. If your property setbacks would not allow building in the area regardless of the former pool there should be little or no impact on home value. Another advantage of removing the entire pool is that with no concrete burried in the pool it leaves less room for error in the backfill process. If a contractor doesn't know how to properly layer the concrete chunks during backfill it can leave air spaces that over time can cause sinkage in the former pool area. This process also eliminates any concerns of seepage as with the partial removal. In my opinion, if you are going to go through the expense and effort of a full removal it is usually worth it the spend the extra money to have it engineered. The cost is typically about 10% more.

Full Removal with Engineered Backfill
       The Process:
       All concrete (Gunnite), fiberglass, liner, re-bar, etc. is removed from pool cavity and hauled off-site. The area is filled and compacted. Provide a demolition and compaction plan wet stamped by a state licensed Engineer, perform density testing and oversight during backfill, and submit a final engineer review declaring the area "buildable"
        Advantages:
     Although this is the most expensive option, it is the absolute best process. In the eyes of real estate and building departments it is as if the pool never existed.
        Disadvantage:
        Cost

     This should give you an overall idea of your options. Keep in mind that there are some variations in between these that may fit your special situation. I tried to simplify "the process" just to give you an idea of what would be done in each scenario but I would be happy to talk to you in more depth about our specialized process for removing swimming pools. I hope you find this helpful and I wish you the best on your upcoming project!

Factors that affect pool removal cost.

2011-02-19T11:11:00.000-08:00

A swimming pool is a swimming pool right? Why the fluctuation in price? In fact, the end result is the same but the process varies depending upon several factors. Below is a list of a few of the most important factors influencing the price of removing your swimming pool.
1. Access: Typically the bigger equipment and trucks that can access your pool the better the price for your swimming pool removal. The absolute best case scenario is to have access such that a large dump truck can backed right up to your pool to dump the fill material right in. This is rarely the case and swimming pools can be removed with much tighter access.
2. Permit: Different cities have different fees for a swimming pool removal permit. The price typically ranges from $150-$1,600. Some of the higher priced permits include refundable recycling deposits that will be returned upon proof of recycling.
3. Size of swimming pool: Larger pools typically require more demolition and more fill material and therefore increase the cost of removal. An average pool contains 25,000 gallons and we have removed swimming pools ranging from 5,000 gallons to 100,000 gallons.
4. Type of Swimming Pool Construction: Liner, above ground, in gound gunnite, concrete etc. These are a few of the different types of swimming pools and each requires different techniques for demolition.
5. Full, Partial, Engineered: These are the different types of swimming pool demolition. Depending on what your plans are for the site of your old swimming pool will influence which technique will suit you best.

These are only five of the major factors influencing your swimming pool removal cost and are very important to keep in mind when you are getting bids for the removal. If your favorite bush stands in the way of your access to your pool you may want to consider the cost of removal and replacement as opposed to the additional cost of your pool removal.

Why Do I Need a Permit for my Pool Removal?

2011-01-27T11:22:00.000-08:00

Clients often ask me why we require that all pools be permitted with the city and/or county.

My typical answer is "Why not". That answer usually doesn't get me very far so I figured I would elaborate.

1. Permit Costs are usually only a fraction of the cost of the job. They typically are over the counter permits that require a simple plot plan, job plan, description etc. An average permit only takes 3-4 hours of work for an experienced pool removal contractor.

2. Property value. If there is a discrepency of County records (ie. records say pool but there is not) the potential buyer may see this as a liability. The cost of permitting the work, if required, would be a concern.

3. Tax benefits. I have been told by clients that they have petitioned the county to lower their taxes based on the reduced "value" of their home without a pool. I have not verified the validity of this so check for yourself.
4. Having another set of eyes "AKA Building Inspector" visit your jobsite verifies that the pool removal process is done to the satisfaction of local requirements and keeps your contractor on track as well.
5. The cost of going back and permitting and unpermitted pool will far exceed the oringinal cost.

6. Most cities will require a plot plan for the permit which will show the location of the former pool. This will be very important if you ever decide to build near or over the site.

7. Neighbors! If anything will invoke the inner tattle tale of your friendly neighbors it will be the jackhammering, trucks, equipment, etc. used to accomplish your job. There is nothing worse than trying to obtain a permit after recieving a stop order from an angry building inspector.

The only advantage to not obtaining a permit is to save $100-$500 in permit cost . In terms of Risk / Reward I feel there is no question here. Hence my "Why not" statement.

If your contractor tries to talk you out of getting a permit or tells you to take care of the permit I would suggest finding another contractor. An experienced pool removal contractor can handle everything for you in far less time than if you do it yourself.

Beware of the floating pool!

2010-09-28T16:10:00.000-07:00

Pool Floated 3 feet out of ground

   Soon the rains will start coming and it will be time to deflate the water wings, put away the margarita machine, and retire it for the season....But one word of warning.... Many of my customers have decided to defer maintenance on their swimming pool and drain it in the mean time. The often unforeseen consequence is that a swimming pool with no water can also be a boat. As the water table rises during the rainy season or water seeps in from the sides, the pool can lift out of the ground. I have seen them as little as 6" to as much as 5 feet out of the ground.
     If the plan was to remodel the pool, it will now have to be removed completely, back filled and then re-dug in the shape of the new pool. A BIG mistake. Alternately, if your plan had been to remove the swimming pool using the partial removal technique it changes the process significantly and would include an increase in price. On the flip side, if you had planned on a full removal it makes no difference exept that we may need to wait a few days in between demolition and backfill to allow the cavity to dry.
Click Here to watch what happened when I poked some holes in the bottom of the above pool....
It actually surprised me that so much water was still under this pool because it was late July but due to the clay type soil in the area it held the water for months.
    If you must drain your pool I would suggest the following to avoid this problem:
1. Break 2 holes. One in the deep end and one in the shallow end. The holes should be broken at least 2 ft. X 2 ft. Do not cut the holes with a concrete saw because you will cut the rebar and the repair will be more difficult. Use a small jack hammer and break small bits of concrete and remove all of the rubble leaving dirt and rebar exposed.
BEWARE: Do not drain your pool completely all at once during the rainy season. It is best to drain it until the shallow end is exposed. Break your first hole in the shallow end. Then drain the rest and break the hole in the deep end. This process does not guarantee that your pool will not move but will reduce the likelyhood.
    Swimming Pools are designed to hold water and that is what is best for them. If at all possible do not drain your pool until you are ready to act on your remodel or removal. If you have any questions regarding your swimming pool removal or draining feel free to call me.

This is Great! Very creative use of a swimming pool.

2010-09-08T12:08:00.000-07:00

I have seen a lot of customers with interesting ideas for their pool but none as creative as this:

Is your swimming pool half full or half empty?

The Argument of Remodel or Removal...
This is the starting point for most of my customers. The pool is 30 years old and something must be done. But what? Can you justify the cost of remodel with the frequency in which you use your pool? Is keeping the pool going to help the value of your home? Perhaps you have always dreamed about having a backyard garden full of tomatoes and squash and the only space is right over the old swimming pool. Over the years, I have seen hundreds of homeowners in this dilemma and have seen them go both ways including one incident when a client went with a remodel and then called me back three years later to remove the remodeled swimming pool! If you are in this situation and need some advice please give me a call. I can come by and give you a no cost estimate as well as refer you to a remodeling contractor.
Below is a list of what some of my clients have done over their old swimming pool:
1. Vegetable Garden
2. Koi pond
3. Basketball Court
4. Worm Farm
5. Landscape
6. Artificial Grass
7. RV Parking

"If I remove my pool, what is the effect on the value of my home?"

2010-03-20T10:39:00.000-07:00

This is one of the most common questions I get from clients that are undecided on whether or not to remove their pool. I am by no means a real estate professional but I have read several articles on this topic and have seen the effects that removing a pool can have on selling a property first hand. Here is my attempt to answer that question...
Most people would like to have a definitive answer regarding this question. Unfortunately, like many other factors in real estate, it depends. Below are some of the issues I have seen that affected property value in relation to swimming pools.

This is a list of factors that may have a flat or negative effect on your home's value.

1. If the pool takes up 30% or more of the backyard.
2. If the pool is over 30 years old and is in need of repair
3. If the pool does not have a safety gate around it.
4. If the pool is made from a vinyl liner.
5. If the geographic area the pool is in has less than 3 months of "swimming weather"
6. If the pool is the only one in the neighborhood.
7. If your area is currently experiencing a drought

This is a list of factors that may have a positive effect on your homes value.

1. The pool is less than 15 years old.
2. The pool takes up less than 10% of your backyard.
3. Most of your neighbors have pools.
4. The pool equipment is relatively new and energy efficient.
5. The geographic area the pool is in has more than 6 months of "swimming weather"
6. The pool is completely enclosed by a safety gate.
7. If your home is considered a "luxury home"

Supply and Demand:
The current economic downturn has reduced the pool of buyers substatially over the past couple of years. According to real estate professionals the best way to get offers on your home is to appeal to as many possible buyers as possible. In general, most families that do not want a swimming pool are less likely to look at a home that has one due to the cost of removal. Whereas, a family that does want a swimming pool will likely look at homes that have existing swimming pools or enough space to install one. Another factor to keep in mind is that if you have a swimming pool and are selling your house, it may benefit you to sell during the summer time when swimming pools are the most attractive to buyers.

Repair or Removal:
If your pool is in need of repair and you are selling your house these are some suggestions that may be helpful.
1. Talk to your real estate agent and ask their professional opinion on the effect of having a swimming pool on your property.
2. Review the above list of positives and negatives and see which you fall into.
3. Get 3 estimates on repairing your pool.
4. Get 3 estimates on removing your pool.
5. Compare the middle 2 estimates of removing compared to repairing and figure the difference.

Example where repair would be the appropriate action:
Base home value: $500,000 Value added for pool: 3%= $15,000
Cost of Removal: $10,000
Cost of Repair: $12,000
If Repaired the total value would be $503,000 (500,000+15,000-12,000)
If Removed the total value would be $490,000 (500,000-10,000)

Example where removal would be the appropriate action.
Base home value: $500,000 Value added for pool: -2%= (-$10,000)
Cost of Removal: $9,000
Cost of Repair: $7,000
If repaired the total value would be $483,000 (500,000-10,000-7,000)
If removed the total value would be $491,000 (500,000-9,000)

Other factors such as landscaping and time factors such as maintenance and mortgage should also be taken into account.

Personal Experience
A large portion of pools that I have removed are related to real estate transactions. Here are a couple of examples that I have experienced after removing swimming pools.
1. A home in Moraga was on the market for 6 months, prospective buyers generally felt the same about the pool, that it was poorly placed and undesireable. I removed the pool and the house was in escrow within 2 weeks.
2. A home in Walnut Creek where the owners needed to move for work purposes was unable to sell their house because of the decreased value due to the real estate slump. In order to rent the home the insurance company wanted to increase the premium drastically and install a gate that was going to cost $3,500. In addition, several renters expressed hesitation due to the pool and the homeowners would be responsible for maintenance and repair. They decided the best course of action was to remove the pool. The homeowners had far more interest from potential renters once the pool was removed. The majority of the applicants had children and wanted to be in the Walnut Creek school district but didn't want the hazards or liability of a pool.
3. An elderly couple in Danville had lived in their home for 40 years. They enjoyed their swimming pool for years but the cost had gotten so high for maintenance that they were considering selling their house and buying one without a pool. The equipment was over 30 years old and very inefficient and they had to pay a maintenance company $120/month to clean it. The total cost monthly was $250. They had never even considered removing the pool until their real estate agent introduced me to them. I removed their pool and they were able to stay in the home that they loved so much.

If you ever have any real estate questions relating to you swimming pool please call me. I would be happy to refer you to a professional real estate agent in your area. The above article is based on my practical experience in the industry and I hope you find it helpful.

A Couple of Top 10's To Consider When Removing Your Swimming Pool

2010-03-19T09:49:00.000-07:00

If you are reading this blog right now, you are most likely among the thousands of Americans who are fed up with the maintenance, repairs, and liability of having a Swimming Pool. I have personally removed hundreds of swimming pools in the San Francisco Bay Area, and thought I would share some of my clients' experiences and how they came to the final decision to hire Dig & Demo to get rid of it.

Top 10 Reasons Most people remove their Swimming Pool.
1. "The kids used it for years and now they have moved out and it never gets used"
2. "The pool is in desperate need of a remodel but the cost of the remodel is too high to justify"
3. "The pool is leaking and the cost of repair is more than the cost of removal."
4. "We are moving out and renting the property and don't want the liability of a pool."
5. "We never wanted a pool but the home of our dreams already had one."
6. "The pool takes up our whole yard and we want room for the kids, dogs, us to play"
7. "We want a pool more suiting of the house (make my round pool square)."
8. "We want to put an addition on our existing home and the pool is in the way."
9. "I drained my pool to save water and it popped 2 feet out of the ground!" True story
10. "I'm greening my home and want to save water and engergy."

Top 10 Things to Consider When Hiring a Pool Removal Contractor.
1. Check the contractors license number at http://www.cslb.ca.gov/ or by calling 1-800-321-2752.
2. Get at least 3 bids from quality swimming pool removal contractors
3. Get a minimum of 10 references and call at least 3 of them.
4. Make sure all project expectations are in writing and only sign the contract if you understand the terms. There should be NO change orders or up charges for a pool removal if bid is done properly.
5. Confirm that your pool removal contractor has general liabilitiy insurance and workers compensation. Also, make sure they will not be using any subcontractors without your knowledge.
6. Never pay more than 10% or $1000, which ever is less, for a deposit. Additionally, never let the payments get ahead of the work.
7. Before work commences, make sure your contractor has pulled the proper permits.
8. Ask your contractor what techniques they will use for compaction and ensure it is appropriate for the soil type.
9. Whoever you decide to hire, it is important that they have substantial experience in removing pools. If the process is done incorrectly, the cost to correct the mistakes will be more than the original cost of the removal.
10. Do NOT make your final payment until all work is done to your satisfaction and all items in the contract have been fulfilled. (This includes the city permit being finalized)

Thank you for reading and I hope you find this helpful. I would be happy to answer any questions you might have. Please feel free to call me.
