Amazing company with a attention to detail. Brandt always goes out of his way to make sure my issues are taken care of. His crew is completely amazing as well they are always same time every week, keep pool and chems tip top and even keep site up in winter. If anyone reading this has a pool and wants some to service they should be using Lewis Aqua-tech if not your missing out and you pool area is too.

Want to also mention Sonya who is always on top of scheduling and meets my needs with meeting on site. This group has customer service in mind first which these days is typically last. Thanks guys looking forward to a great season 2018!

Joe Gwiz and his team are terrific. I could not recommend them more highly. He was prompt, accessible, and accountable. If you are even thinking about installing a pool, this is the only company to consider. His team was courteous and respectful.

We have been using them for years for our pool service. Dave Cox (service and repairs) and Sonja Howard (admin) are great. Their guys do a consistently thorough job of cleaning and maintaining our pool and they are super responsive to requests for repairs and other issues.

Every staff person we have worked with are quick to respond, pleasant to deal with and professional. Each area manager gets the job done regardless of our request. The maintenence team that keeps the pool and spa operating are terrific. Can't say enough about Lewis Aquatech. Design, construction and maintenance are all great. They make it easy to have a pool and spa.

Our Clifton swimming pool equipment (filter pump and booster pump) required replacement on 13 June 2022, and Dave Cox, Alfredo and Jose were outstanding in their prompt responsiveness, customer service, and efficiency--they were all enormously kind and gracious, too! Our pool is up and running, and sparkling clear thanks to them! I would highly recommend Lewis Aquatech--they are true professionals--demonstrating spectacular, and rare qualities these days!

Lewis Aquatech designed and built our pool. I have recommended them wholeheartedly to friends who are looking for a pool builder. They provide the best quality product and design, and have worked on the surrounding landscape to fit flawlessly. What I will add is that their maintenance is also what separates them from their competitors. The regular maintenance crew is always on time, the same people are always there, they are knowledgeable and they leave the place absolutely spotless.

The few times we have had an issue (with torrential rains, etc.) a quick email to Dave, the service manager, results in an immediate dispatch of his crews. They are usually there within 24 hours and sometimes the same day. We trust them and appreciate both parts of their business, construction and maintenance.

Excellent customer service! A truly magnificent end product. Our pool designed by Lewis Aquatech is our little heaven on earth. The team professional and their customer service and pool service is beyond amazing! Today is July 4, 2020, a holiday. Most people are with their families celebrating. My pool cover was not opening. I text Joe and Brandt and the Lewis team.

Within 40 minutes a tech was over at the home working on the solution. Everyone at Lewis Aquatech is a joy to work with. Joe Gwiz and Brandt are just some of the awesome folks at Lewis. Thank you all for making our pool experience day and night so enjoyable! - Dr. Tarique Zahir

We contracted with Lewis Aquatech in 1998 to design and build a magnificent negative edge pool on a stunning site in McLean overlooking the Potomac River. Their design was beautiful, their price was competitive and their references were strong so we selected them to build and maintain our pool. We are still very happily working with them and we have never regretted that decision in any way, shape or form. Lewis Aquatech is a family owned business. Brothers Don and Joe Gwiz cheerfully perform on their promises with no excuses, renegotiation or disappointment.

These guys are smart professionals with real integrity. They also have longevity in their employees, which is a huge plus and also speaks to the company's good culture. I think the fellow who tiled the pool over twenty years ago is still with them, as is Valente, the service manager who dutifully comes to open and close the pool and address minor maintenance issues, of which there have been precious few.

I recommend Lewis Aquatech in the strongest possible terms as a pool designer and building and maintenance contractor. Life is short but it will be more pleasant if you pick a good contractor like Lewis Aquatech. Thank you Lewis Aquatech! Mark B, McLean VA

Please forgive the lengthy review, but I've detailed my POSITIVE experience with Lewis Aquatech (LA) below: Project: We contracted with LA to build a pool and spa, as well as hardscape our backyard. Our pool is 14x30, and our spa has 8-person capacity and "Waterfalls" in to our pool. The stone we chose was travertine, and we partnered with LA on some lighting design.

From the get go, their architect (Besim) had a clear vision of what our yard could look like. More importantly, he listened when we said we liked/disliked something, and made those adjustments to the design. Ultimately, it was a partnership in getting to a final product. Timing: We first engaged with LA in late 2019, and after we signed the contract, we broke ground in March and the job was completed in Mid-June.

Given the COVID world we are living in, we were thrilled with the timeline. Worth noting, we do not have a sprawling yard. We live in Ashburn, and have what I would consider a typical yard (size wise). The Pool Building Process: Ask questions. Lots of them. Building a pool is hard, especially if you have never done that before. The consultations allowed us to come up with a collaborative design. Choosing the stone, color of your pool water (thats a thing), etc.all was done in a very fluid manner.

Our PM Judd was fantastic throughout the process. Always took my calls, always responded to text messages, and always got us the answers we needed. We understand the timeline, and worked towards the finish line. COVID did present some challenges, but even through all of it, the team was professional and managed our expectations. Bumps in the Road: Sure.there were a few.

But what contractor driven process doesn't have bumps. But I can emphatically say that there were never any "hills" or "mountains" during the build. Small bumps, always handled with professionalism by the LA team, and nothing that wasn't addressed immediately. Price: Though I won't discuss the price our project, I can tell you that we did get other quotes and LA was the best value for comparable pricing.

Even during the project, we decided to make a pretty substantial add-on. Joe and team partnered with us to leverage some economies of scale and ultimately we came to a number that worked for both parties. End Result: Pictures attached. Our pool, spa, and hardscape is amazing. What LA was able to do in what I consider a limited space is incredible.

The attention to detail (our drains and skimmer baskets were hand carved in the travertine), the strong level of communication, and the willingness to go above and beyond when needed made this a great partnership. I would highly recommend Lewis Aquatech to anyone that is considering a pool project.

One of the many things that I love about Lewis-Aquatech - and I tell many people who ask about our pool and pool builders in general - is that your Team is fantastic, knowledgeable, kind and very customer service oriented! In addition, you Team has been with you for many years - which means that you treat the Team right, and they love working there.

Such an important factor in today's world, and your industry specifically. Kudos to all of you for making it such a pleasant environment, and how that translates to excellent customer service. Thank you!

Outstanding customer service and responsiveness! Last Sunday, the main pump to our pool died. A quick email to Dave Cox at 1 PM on Sunday. Less than one-half hour later, Dave responded letting me know that they would be out Monday, Tuesday latest. Well, Team Aquatech arrived on Monday, early afternoon. They worked diligently in the pouring rain (a not uncommon event this summer in Northern Virginia) to replace the old pump with a new one.

This responsiveness and dedication is their standard. Lewis Aquatech has been servicing our pool for 11 years now and I never hesitate to recommend them for any pool-related job, big or small. Counting on good, responsive companies these days is rare - Lewis Aquatech is one of those rare jewels.

Lewis Aquatech did a great job helping us fix an issue with our pool caused by faulty workmanship from a previous contractor. The salesmen Brandt was responsive and helped navigate us through the process. Frank and his helper Eddie were very nice and clearly had a desire to get the job done correctly and make sure everything was right before they left.

They even sent a crew out to vaccum the dust and debris out of the pool so that the pool is clean when we open it in the spring. We would definitely reccomend Lewis Aquatech and will use them in the future.
