"Our two-story home was in dire need of exterior painting and weather damage repairs. Elite Enclosures team is skilled and responsible, polite, positive and efficient. Adam Martin strives to communicate with us, so that we have full understanding of the project. The crew are polite, friendly and good humored, but constantly working. The weather damage required a new man-door frame installation and the double garage door needed dry rot removal and mold removal, including siding replacement. The resulting repairs are exceptional and we are impressed. We have hired the same business to replace a dry-rotted fence and build a new gate, all done well!"

"It all went well. We came home from a vacation to find our 24 year old furnace had conked out during a very cold snap in December. Aire Serv sent someone out the next day who gave us all the options available. Salesman was professional and knowledgeable. He provided us with electric heaters to bring our house up from 40 degrees to our comfort zone of 67 degrees in bedroom, kitchen and family room for the weekend until the installers could come. The installers were polite, professional and punctual so that we were up and running the new high efficiency furnace the same day. Business office was helpful in providing the documents and information needed for the energy rebate. Love my new smart thermostat."

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
