At Evergreen Home Exteriors we are all about our customers. Our philosophy is simple. We give customers the kind of experience we ourselves would want. Everything we have learned about customer service has been from our experience as customers and feedback from our customers over the past decades. We have developed a seamless communication system that allows our customers constant access to their project, no matter what phase of the process they are in. If you are tired of the mediocre service that has become the new normal, then give us a try! We will make you a customer for life!!

"As the GC for my own full home renovation, I was looking for a turn-key company that I could outsource and trust to handle the exterior work for my house (new house wrap, siding, and window/door installation). I was really optimistic about this company because they were a Hardie-certified installer. I hired them to install about 30 top-of-the-line Andersen windows, several exterior doors, and install all new Hardie siding and trim. Unfortunately things went south on day 1 and continued to spiral out of control. In a nutshell, I had three different project managers assigned to me throughout the project, and neither of them came on site once the project started (until the very end, and the last project manager was awesome... kuddos to him!). The first crew that came on board were subcontractors, not Evergreen employees. When they started to install my windows, I knew immediately that they did not know how to properly flash a window sill (they had gaps in the Vycor flashing, didn't wrap the sill properly, etc. etc.). I called this to the PM's attention but nothing was done. The crew installed all windows in one day, not properly flashed. Crew was retrained and came back to "fix" them, but still didn't properly flash them. Meanwhile, they were taping the seams on our house wrap in the rain, when the house wrap was wet, so nothing stuck and had to be redone. Fortunately this crew was let go and I was told they were going to bring their "in-house" crew to finish. The next crew was awesome and they ended up removing all windows and reinstalling them. In total, each window was installed three times! As a result, some of the nail flanges and seals were broken. I called this out to the PM and owner of the company but did not get a response. From this point on, the crew that stayed on did a good job and was pleasant to work with (but I found out they were also subcontractors, not "in-house" employees as I was told up front). The delivery of a few windows and doors were delayed by about three months, which was my responsibility. I told all project managers about this upfront, including the first project manager before the project started. He said it was okay and that we could start the project and hold back a specific percentage amount of the project payment until they arrived so they could return to complete it at a later time. He and I agreed and the project moved forward. When the owner of the company, Jon Jordan, found out about the window/door delays, he was irate. His brother/GM and PM (who were both very polite and professional) called me and tried to negotiate a higher partial payment percentage rate which was absolutely frustrating to me. I explained to them that I had suffered for months through the project with extreme errors and redos, which caused mental angst, and that we had already agreed on a percentage on day one. Nonetheless, I was willing to increase the partial payment a little bit just to wrap things up. The owner followed up that evening by texting me in an aggressive, threatening tone. He said my only options were to allow them to finish the project immediately (which was impossible because we didn't have the remaining windows or doors), or pay them in full immediately and they would return after the doors/windows arrived a few months later. Otherwise he would sue me and put a lien on my home. He and I hadn't even spoken prior to that, and it was shocking to get such an aggressive text from a guy who never even heard my side of the story… I proposed to the owner that we cease the contract immediately, and that I would pay them for all work completed at that point. We agreed on how much work was remaining, and removed that amount from the contract price. We cancelled the contract, he had his remaining materials picked up and that was that. Again, I was hopeful for this company and wanted to have a great experience, but due to the poor project management experience, inexperienced subcontractors who caused damage and significant delays, and a sue-happy, angry owner who lacked professionalism and compassion, I could never re-consider hiring, let alone recommend, this company for any type of contracting 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.
