"Bryan Rodriguez, the owner of Nord Fence, undertook the installation of a covered patio at my property. I am writing to confirm that Bryan and his team failed to execute this job by industry standards and best practices. The company improperly attached a covered terrace to my existing roof. After several expert roofing assessments, it has been determined that their work did not comply with established roofing codes and regulations. Consequently, my entire roof now requires replacement due to the structural integrity being jeopardized by condensation and water damage resulting from the negligent installation. Furthermore, the actions of this company have compromised the integrity of my metal roof, which may expose them to potential liability for damages incurred. Despite multiple attempts to resolve this matter amicably, Bryan has been unaccountable and has not followed through on any communications. I am deeply concerned about the financial implications of these repair costs and disheartened that a company would engage in such practices that exploit consumers. Given the circumstances, I am considering further legal action to address these grievances and seek appropriate remedies."

FAQs for swimming pool heaters installation and replacement projects in Bellevue, WA

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.
