"I just had my pool resurfaced by Millennium Pools with Pebblestone. Yan Larenas ((Project Manager) and Elmer Lopez (Superintendent) have been outstanding. They are both very nice, patient (especially since I?m a worrywart), knowledgeable, communicative, organized, and conscientious. At least one of them was here each day of the project to ensure that I was pleased and to personally take care of any items that may have been overlooked by the crews. They are rare individuals who care about their customers and have pride in the work done. I was informed every step of the way and there were no surprises. I have a gorgeous pool now and it went so smoothly, without stress due to Yan and Elmer. I can?t overemphasize how impressed I am with them and how happy I am with my new pool. Thank you so so so much! Norbert Juelich"

Freedom Fence and Deck specializes in affordable top quality maintenance free decks and fences. We are an owner operated company with zero complaints. We also have earned a A+ rating with the Better Business Bureau. We offer a limited Lifetime Warranty on all our work. Angie's List has awarded us the Super Service Award three years in a row.
"Everything went smoothly from the sale (onsite, at our home, with samples of materials and a quote at the time of the visit), to communication with the main office (regarding timing of construction, follow ups on payment milestones) to the construction (which was expertly handled by a crew of two guys who work for the company). The owner himself came out to install plugs in the screw holes on one side of the deck, after the crew decided that the original plugs were not a good color match. We appreciated that attention to detail and the fact that the company handled it without our even knowing it had been an issue. The crew made sure the construction area was clean each day when they left. Our bluestone patio and surrounding landscaping were in good condition after the work."

Swimming pool heaters installations and replacements FAQs
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.
