"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."

"Choice was fast, efficient, and kept me posted on the progress of the claim. Although the water leak issue was discovered on a Friday, they had a plumber there to investigate by Saturday morning. When it was determined that the 20+ year old heater needed to be replaced, the replacement ordered, on-site, and installed by Wednesday morning. I am glad that we opted for the Choice Ultimate plan as other than the initial $65 service fee, all but one $50 ancillary expense was covered."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

"We hired Walls to come out and move our hot water heater that was located in our laundry area to another location in preparation of an addition to my laundry room.  In order to move the water heater an old water softener system would need to be removed and disposed of.  The work was completed in one day and everything was cleaned up very nicely when they were done.  Mark and Brian were extremely professional and friendly to work with."

"What you really need to know: Hector Martinez did a great job.? Very responsive to my questions, fair price for the work completed.? Timely, polite, and well-mannered crew.? We did not know exactly when the hot tub we ordered would be delivered by the trucking company and were concerned that it may have to sit in our driveway for several days.? Hector made sure we knew how to contact him so he could have a crew over here the day it arrived to install it - which they did.? Last, but not least, while doing the work, I asked him to look at the roof over our sun porch.? The gutter was sagging and would not stay up.? Hector and his crew looked it over and let us know a section had to be replaced.? He gave us an honest price, didn't tell us more had to be fixed then necessary - I really would not have known either way.? An honest man.? We would gladly use them again."

FAQs for swimming pool heaters installation and replacement projects in Knoxville, 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.
