"Dave arrived at the property on time and from the start I appreciated his professionalism.  He was very knowledgeable about the home's construction and immediately noticed safety hazards that I had overlooked upon my own, limited, cursory inspection.  None of the items he pointed out were deal-breakers, but before we went into final contract I was able to get the Sellers to repair these deficiencies (loose front pavers and handrails, leaking basement sink, uneven pavers around the pool, etc.).  He indicated which parts of the outdoor backyard wooden deck were subject to wood-rot and he also pointed out parts of the roof that might need a professional roofer to later address.  He pointed out that the water heater was ending it's useful life (over ten years old) and his concerns about the electric panel box (wattage input and wiring) were later addressed by the Seller to my satisfaction.  The professionals he brought in for the septic tank inspection utilized fiber optics, permitting a full examination of the septic tank, verifying that a new septic system had indeed been installed, correctly, as the Seller had asserted.  From the darkest corner of the basement to the dimly lighted attic, Dave gave valuable insights as to the construction-quality of the house.  I was very satisfied with his thorough report and the reports of the other inspectors.  Without reservation, I recommend Dave Polo & Associates very much!"

"Gregory and his staff did an excellent job! They collected and bagged leaves and cut grass in a very timely manner. They also neatly stacked up the bags of leaves on the curb and cleaned our gutters. We will definitely hire again!"

"From our first meeting with Mike we were sold on Custom Pool Pros and Paver Pros. We met with may other "custom" gunite pool installers who gave us the book to pick a shape from, not really custom when you pick a shape. Mike designed a pool to fit our yard and budget and provided us with a drawing of how it will look when its done.



Custom Pool Pros handled all the paperwork for permits and once approved the work started. Despite some rain delays the whole project, which has now grown from the original idea, is finished. Every time i had a change or question Tom was there to answer the question and provide his input when needed. Overall the experience has been great and I would recommend them to anyone looking for a superior quality "custom" pool.


Just to touch on details, Tom's guys are professionals, they take great pride in their work and it shows in every detail. They are very particular in everything they do down to the placement of each boulder or paver they place. We can't wait to enjoy our new pool and patio for years to come.



Custom Pool Pros handled our whole job from digging the hole, forming the pool, setting the slide, placing the boulders around the slide, installing the perimeter fencing and all 3200 sqft (give or take a few feet) of paver patio surrounding our pool.


This is a large expenditure and I don't regret one penny of the incredible backyard dream that Custom Pool Pros delivered."

Install Above Ground Pools FAQs, answered by experts

Generally speaking, you should expect to wait 24 to 48 hours after filling a pool before you use it. However, the actual timeline depends on a few factors. Most importantly, you need to shock the water with chlorine or an alternative to swimming pool chlorine and let the concentration come down to a safe level before using the pool. Additionally, most water sources will be cold, and it can take days before the sun or your pool heater warms your water to a comfortable temperature. Alternatively, getting water professionally delivered could have you swimming in just a few hours.

Calcium lumps in a pool are calcium deposits that form when a pool's water parameters are not in the normal range. They can float around on the surface of the pool water, making it look and feel dirty. The most common causes of calcium lumps in pools are calcium hardness above 1,000 ppm, alkalinity over 120, and a pH over 7.8. Keeping your pool’s calcium levels, alkalinity, and pH levels within the normal, safe ranges is the best way to prevent calcium lumps and other problems, including damage to the pool surface.

Remodel costs vary, often 50-70% of new construction costs, depending on remodeling depth and choices for feature additions or modifications.

High alkalinity, which is above seven on the pH scale, is the result of improper chemical levels in the pool. Each chemical you use to keep your pool clean has a different pH, so a ratio that isn't optimized for your pool size may cause the number to go above 7.8, the high end for a good pH range in most swimming pools.

Size is the main difference between a pool and a spool. Spools are typically about half the size of an average pool, so they’re ideal for yards without the space for a full-sized pool. Spools are also easier to heat, so they tend to be a higher temperature than pools and can be adjusted to get as hot as a spa when it’s time for a relaxing soak. Spools also contain jets and blowers, while most pools do not.
