"Watermark carried out all defined services professionally and thoroughly. I received proposal within 3 days after requesting one. The proposed cost and work coverage was better than others I had received. Nick came to the house once I requested a proposal and reviewed the pool area so that his proposed work would be reflective of all conditions of the pool. The overall work was carried out professionally and the end result left me with a 'new pool'. The pool is relatively large (20 X 45)- 31,000 gallons and I now have a pool that is something I am proud. Nick stayed on top of all work in progress and kept me informed of each step and what was expected of each step. There were no hidden costs or surprises during the job or at completion."

"At first my experience with Dystempool was not good. I made an appointment for a Monday, waited at home all day and they never showed up. Tuesday morning I sent them an unhappy email. Nick answered it, apologizing that he was out of town and his technician had suffered an injury. He promised to get there that day. Nick arrived late in the day and worked all by himself into the night and did a very thorough job. He spent a lot of time clearing the line for my waterslide. I was especially impressed that he was able to install my Loop-loc cover all by himself. The next day I noticed he had replaced one of the cover anchors and didnâ t charge me for it; didnâ t even mention it. His fee was $100 less than my usual company charges and they couldnâ t get me in until November. I am more than satisfied with the work Nick did and I plan to hire him for my spring opening. This is the kind of hard working small business that America is famous for. I heartily recommend Systempool for your pool service needs."

"We are trying to find somebody to put a pool in. We called the one that Angie's List recommended and it is called Dig-M-Installers. I went to get the pool and the pool wasn't there. They didn't have the pool's parts. The other company is guaranteeing me that they will have it by the time Dig-M-Installers has scheduled the appointment. We got the quote from Dig-M-Installers. We got the paper work and everything from Dig-M-Installers. My wife got them from Angie's List. Their normal quote is 1029 dollars. I am getting a discount because it is before some date. I am getting it for 928. They are knocking off a 100 dollars. It was the only one on Angie's List and when we went on the phone book a lot of them sounded shaky. We took for granted that the one that Angie's List has was very good. The people that I came in contact with were very kind and very courteous. I saw an older man but to me they are all young as I am 70 years old. He was in his 40s and he was very nice. He was explaining to me how they would like to put it in, where they would like to put it, which would be the best situation where it won't cost me more money to have it done. They are very nice and clean. So far it is real good. They were very professional. Considering responsiveness, they were right back, right away. With this one man so far, it was very professional. I am waiting for them to install a pool and that is the next situation. I will know better once they install a pool."

"BJ Pool & SPA is a first rate company.  Bob, the owner, has been working with pools for decades and knows everything about pools. He is actually willing to try to repair equipment, unlike many other lesser companies that merely put in new stuff.  If you have any issues with your pool and spa, these are the people to call: they will fix anything and will always provide you with the best options.  Bill, the specialist who came to work on the unusual configuration of equipment for my small indoor pool and spa, demonstrated a great deal of experience, ability and honesty.  BJ Pool & Spa might not seem cheap, however, given their vast knowledge, experience and technical ability, they will provide you with quality service and advice that will save you money in the long run.  Their competence and integrity is extremely reassuring.  It isn't always easy to find a good pool company (this industry isn't as regulated as other professions), and it took me a while to find this one. BJ Pool will be the company I call when I want honest and reliable service

"Larry and his crew upgraded our under cabinet lighting with new LED lighting, and specialized outlet. Not only was our home and its contents treated as if they lived here, the job was done professionally. So much so, that the only issue we had was when the switch/outlet face plate screws came loose. I didn’t even bother calling Larry, I tightened them myself. The lighting is on, literally 24 hours per day since the install, with zero issues. Love these guys."

Hristo did everything possible to get the job done. This particular June 2016 was filled with many rain days and made his schedule hectic. He kept me in the loop and was up front and honest about the delay noting vinyl liners must be installed in dry, sunny weather - none of which came for a few weeks.

The job was handled quickly and professionally while his team made several visits to complete the job. During this time we got even more rain but the liner was installed by then and they finished all well within the timeframe.

I write all this because Hristo kept me informed which I appreciated and which has earned him and his team my respect and gratitude.

A job more than well done! Also, within budget :)

"The GPro team were so meticulous! They measured really carefully and the result is a walkway that is not only beautiful, it drains water away from my house. I won’t have any more puddles or ice patches to contend with. They were also really careful to preserve the plants I wanted to keep, so now I have a lovely walkway and my garden is still intact, too. I’m really pleased with their work."

"Happy with pool surface...mini-pebbles with glass beads. Weekly maintenance during pool season since 2016. Paul and his team are professional, courteous, caring, hardworking and kind. Paul even came over on Labor Day weekend when our pump was not working...now that is above and beyond! Paul really cares about his clients and their satisfaction. Prices are fair and comparable. The water is always crystal clear and thankfully no one has ever gotten sick from swimming in our pool. Thank you, Paul and VIP Crew!"

FAQs for swimming pool heaters installation and replacement projects in Kensington, MD

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
