Custom Construction Designs LLC

Dennis and his team are wonderful. The quality of this pool is top notch, much better than you'd get with a more commercial pool company and it will be more affordable. He's been doing this for years and his expertise shows. Certain things outside of everyone's control (labor shortage and supply chain delays) made for the project to take longer than initially expected, but the product we got at the end was so very worth the wait.

Dennis and his team are simply the best. From our first meeting and throughout the construction of our pool, Dennis was available, friendly and flexible. No question or request was too much! We received personal attention along with top notch craftsmanship. Dennis is a hardworking, honest professional who you truly enjoy working with. We highly recommend Custom Construction Designs.

Denis Sullivan and his team did a first-rate job renovating our pool: on time - actually earlier than originally anticipated - within the quote, excellent workmanship by all trades with regular progress updates and pictures as the work progressed. I recommend Denis and his company and crew without reservation.

Dennis Sullivan and his team renovated our 40 year old gunnite pool. They replaced the skimmer, installed new tile, reset some of the copings and resurfaced the pool with the eco finish. They were responsive on a timely basis and did an excellent job. We found them easy to work with and would recommend them highly.

I asked a well known pool maintenance person in our area who he would have build his pool and he said "only one guy would I have build my pool in Connecticut, and that is Dennis Sullivan/Custom Construction Designs LLC". I called and got an estimate. They did an amazing job and were a pleasure to work with. They walked us through each part and were present throughout the entire process. They will work with you to build the pool of your dreams. They worked very hard and completed the project as quickly as possible. I recommend without reservation this company and am beyond thrilled with our pool!

The most professional, thorough, friendly, trustworthy, hardworking and most importantly, honest contractor we have ever dealt with in both of our lives! He is punctual, articulate and down to earth! There is no better. Dennis Sullivan is simply the best contractor we've ever encountered!

Custom Construction built our pool in 2013. They did a beautiful job and were a pleasure to work with. There were multiple contractors working during the project and they worked well with each of them. They have provided ongoing support and maintenance since we opened the pool and they have always been responsive and committed.

Great company to work with......did an excellent job and very quickly! We are MORE than pleased with our pool and spa, turned out beautiful. Dennis was a delight to work with and has a wealth of experience building pools. Highly recommend!

We couldn't be happier with Custom Construction Designs. They were with us from beginning to completion of the project, and continued to teach us how to best care for the pool. Every concern and question was immediately addressed. We never received the run-around. There couldn't have been a better team to work with.

Sunfox Campground in Lisbon CT was seeking to install a heated, zero-depth beach entry pool with an L shaped design, as well as a whirlpool spa. Although I knew many "residential" pool installers, none were able to handle our "commercial" installation...and only some really big companies were willing to provide a quote. Luckily, we came across Dennis and Custom Construction Designs. After a 5 minute conversation, I knew we had found our pool professional, as he understood all the intricacies of our plan. Despite being delayed by some zoning issues, Dennis was ready to start as soon as all permits were in place, and the estimated construction time was very accurate (which was 7-8 weeks for our project). It is rare to find your pool contact person is on the job site so frequently with his crew. We got to know his staff, and they were always willing to help tweak plans as the installation progressed. He also allows you to determine which components of your pool plan should be handled by his company, or by any preferred contractors you might have (in terms of landscaping, deck options etc). We chose a gunite pool and a stamped concrete deck, and he offered a few options for deck and fence companies. We discussed all potential upgrades, from filter systems to lighting and pool surfacing, and he was up front about any added costs of those options. Whenever I woke up in the middle of the night with some unfounded concern, he always responded to my early calls or texts. He is familiar with all aspects of the pool industry, and knows where to get answers for any questions that may be unique. Take your time when selecting your pool installer, as any salesperson can sell you a pool...but will they be the one you call if you have any questions? We strongly recommend Dennis Sullivan and Custom Construction Designs for any pool installation or upgrade.
