Inground Pool Liners

Vinyl Liners for In-Ground Swimming Pools

We specialize in new replacement vinyl liners for in-ground swimming pools.

Fit- All in-ground swimming pool liners are custom made to "fit" your pool.  Inground liners are seamed at the factory based upon the measurements provided by the installer.  How well the liner "fits" depends on how well it was measured.

We have been measuring liners since 1989 and have experience ensuring that you get the right "fit".

Finish- Most inground swimming pool bottoms need work after 15 years.  The pool bottom should be patched with either cement or vermiculite. The pool bottom should be cleaned and any imperfections taken care of. It should be smooth to the touch thereby ensuring a longer lasting replacement liner.  Attention to detail matters when changing an inground liner.

Our exclusive Ultra-Seam™ process makes floor seams stronger and virtually invisible, creating nothing short of an entirely new category of vinyl liner. You can rest assured that not only will your liner create a beautiful look for your backyard, but whatever pattern you choose will present a seamless appearance. No more visible floor seams detracting from the beauty of your pool.

More choices, more exclusives

Inground liners are available in 20 Mil and 27 Mil material. We offer over 30 different elegant and exciting liner designs.

In-Ground Liner Testimonials

"I recently had the liner replaced on our 25k gallon in-ground pool, along with the relocation, purchase and installation of all new equipment.  I was referred to EZ Test by another business who I trust and I couldn't have been happier with Pat and Dave.  They are pros and their customer service is top notch!  We made a few changes along the way during our installation and each question and  request was responded to quickly and efficiently.  They are easy to reach, quote a reasonable price and stick to it.  There were no surprises or hidden costs that mysteriously showed up at the end of the job, which I have seen happen with other businesses.  My newly installed equipment is working great and my liner fits like a glove.  I will use EZ Test for my pool openings and closings and for my future pool needs.  If you are looking for a solid company that does high quality work for a fair price and calls you back when you call them, this is the pool company for you."

"Pat - just need to tell you, LOVE the pool.  I was on the fence before the water went in.  It was really really BLACK and I was questioning my choice, but with the water in, sometimes it's Navy Blueish and sometimes a Hunter Greenish, and looks irridescent in the sun.  It really really looks great.  Like a lagoon, but yes, can totally see to the bottom so no worries there!  Blends so well with the landscape in the sense of looking more natural than an aqua or teal liner.   Plus, the temp in the pool is 86 degrees!  I was in the pool all weekend with the kids and I'm never in before end of July.  It's never been this warm this quickly and we've had some really hot summers over the years.  You guys did a great job on the install, not to mention you really accommodated our schedule, and well, we're just pleased all around.   Thanks so much!"   -Kristin A.

"I am writing this letter on behalf of D & P Swimming Pool in Plaistow. I have been the property manager for Churchill Court Apartments in Haverhill for over 23 years.  It took me 3 years before I found a pool company I could count on for all of my pool needs.  20 years ago I hired D & P to completely re-do our deck area.  They did an excellent job and it was done in a timely manner with no loss of pool time for our residents.     Since that time, they have installed new filter systems, supplied us with all our parts and chemicals and maintained the pool area within any and all codes.  Last week they installed a new vinyl liner for us.  Our pool will once again be ready to go in plenty of time for opening day.     If you are in the market for a company to handle all your pool needs with the utmost of professionalism, call Pat at D & P Swimming Pool.  He will take the time to review with you all your needs.  I trust you will be extremely satisfied.     Feel free to contact me at 978-373-4046 if you have any questions.  I would be happy to talk with you. Sincerely, Maureen MacQuarrie"  Property Manager - Churchill Court Apartments - Haverhill, MA

It looks terrific and everyone who has seen it comments that is looks like a new pool!  Water is in,, filter is up, chemicals in, and water is clear! Eric was just terrific in all aspects of the project. Kept us informed and did a great job. Overall, he went above and beyond to try to please us and it showed in his work results. Again thanks to your guys and your crew. If you ever need any future references don't hesitate to call us, we would be pleased to provide them." Gil Boilard   Nashua, NH


"I contacted E-Z Test for a new liner for an old pool. I was more than pleased how they explained the contract , answering all questions in detail, leaving nothing unsaid. They shower honesty and professionalism to the highest extent, including all of their employees. On a scale of 1 to 10 -- 10 being the highest, I give them a 15. They are a company that we rarely experience these days. Very happy with final result." -Cecile B    June 5th, 2014
