"These guys were awesome. From the planning to the building of our project. They gave us an accurate estimate. Even added an accessibility ramp at our request and fit it perfectly on the deck they built for us. They were able to start our project a week ahead of schedule and even worked in weather that was very cold. They were efficient and quick. They cleaned everything up when they were finished and I couldn’t have ask for more polite and professional service. Will definitely contact them for future projects!"

"We had a partial deck built for our above-ground pool, and the whole experience was excellent from start to finish. Jim the owner, was great at communicating, he went over every detail with us beforehand, and even came out in person to check on the progress to make sure it was going well. It was clear he really cared about making sure everything turned out right. Simon was the one who built the deck, and he did a beautiful job and made it look perfect. He took our ideas and brought them to life exactly how we pictured it, with great attention to detail and craftsmanship. The deck feels and looks amazing, and has completely transformed our pool area into what we wanted.

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

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.
