For over 20 year Pools Unlimited has been installing new pool liners all over Western New York. With hundreds of installations, we have the skill and expertise to get this work done properly.
How much do inground pool liners cost to replace?
In general, an inground pool liner replacement cost is between $3000 and $6000. There are a lot of factors which go into this cost including the size of the pool (12 x 20 vs. 25 x 45); the type of liner chosen (plain vs. print; 20 mil vs. 27 mil); the pools' shape (rectangle vs. freeform); the structure (steps vs. no steps vs. steel steps covered with the vinyl liner); the pool base (portland cement vs. vermiculite). In addition, the number and make of the skimmer(s), return(s), main drain(s), stairs, light(s), pop up cleaners, etc... will add to the cost because we change out the face plates and gaskets of these items to give the pool a "new" look and to prevent water leaks from old worn out gaskets.
How long does it take to replace an inground pool liner?
The whole process takes approximately 4 weeks broken down as follows:
We measure each pool individually and have the liner custom manufactured for your pool. This assures a proper fit of the liner and the longest liner life expectancy. (An off the shelf liner placed in your pool may have excess material which will result in wrinkles; or it may be short and be stretched more than recommended resulting in the material being thinned out). The measurements are sent to the liner manufacturer for input into their computer system. Here they check for any discrepancies in the measurements to make sure no mistakes are made in the manufacturing process. This process takes about a week to complete.
Once the measurements are confirmed, the liner is manufactured which takes approximately 3 to 5 days depending upon the backlog at the manufacturer. Once the liner is complete, it is shipped to us which takes another couple of days.
Once we have the liner in our hands, we prepare for the installation. Weather permitting, we begin the installation which will take between 2 and 3 days depending upon the size of the pool, the condition of the pool, the condition of the pool bottom, and water pressure. On the first day the old liner is removed, the pool bottom is fix/cleaned, the new liner is installed and vacuumed in, and the filling begins. On day two, depending upon the fill rate, the skimmer and returns, and stair kit can be cut in. Once these are cut in, it is just a matter of filling the rest of the pool. Sometimes the water pressure is not strong enough to allow us to cut the stairs, returns and skimmer until the third day.
How long do inground pool liners last?
The life expectancy of the liner can vary from pool to pool. I have seen liners that need to be replaced in as few as 8 years due to bad water chemistry which caused the liner to wrinkle (low pH and alkalinity will cause this); and I have seen liners last over 20 years. The average seems to be approximately 15 years.
What is better, a 27 mil liner or a 20 il liner?
In my opinion, the thickness does not matter. Anything that is sharp enough to puncture a 20 mil liner will most likely puncture a 27 mil liner.The major cause of liner failure is not due to punctures, but improper water chemistry and the use of oils and lotions in the pool. These lotions and oils accumulate at the water line and are then baked into the liner by the sun causing the liner to dry. The use of an enzyme in the water will eliminate the "soap film" line caused by the oils and lotions and make the liner last longer. A second consideration is the shape of the pool. If your pool has rectangular corners or small radius corners, the 20 mil liner will stretch into these tight areas better. The thicker liners will not stretch back against the base of the pool or the walls and will leave a gap behind the liner.
When is the best time to install an inground pool liner?
The best time in the northeast is from mid June thru the end of August. The reasons is that the ground water table is lower at this time which reduces the likelihood of ground water damage to the pool base when the pool is drained; and the weather is warmer which softens the vinyl making it more pliable so it stretches into shape resulting in a better fit.
