"I recently had an asphalt driveway put in. The crew was very professional. The driveway is smooth and very happy with the quality of the new driveway. They even went above and beyond and put in a small drainage area for water runoff. It has definitely improved the appearance of my home."

In business since 1964, we are fully licensed and insured and one of the few area firms EPA lead certified. We will provide excellent recent references. We work with your architects or ours. additional website: decksofny.com. crosscountyhomeimprovement.com

"Dave and his team were wonderful to work with. We met with several contractors for our new deck and Dave was recommended by our architect. He was extremely responsive and we found his rates were comparable to others we received. We were stalled for a while due to Covid, but once our permit was approved, Dave kicked off work for us the next week. He was very communicative, sharing updates, hiccups (fortunately not too many - usually product delays), and recommendations. I can't say enough good things about his crew. They always arrived on time and worked diligently. They also indulged the many questions my husband and I had! We've already recommended Dave to another friend and would happily use him again for future relevant work."

"Learn from our experience, save yourself the headache and do NOT use this company. We made the mistake of using Deluxe Pool Services to replace our pool liner. The company took incorrect measurements for the liner resulting in a liner that was too large for our pool with huge wrinkles on the walls and floor. Further, the company cut out holes for the return jets before any water was added to the pool, resulting in a stretched liner that leaked around the jets. Within 1 hour of the installation we were losing water and the company refused to come back when called."

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.
