"Our crawl space now has an R19 insulation value, the musty smell is completely gone and it is a usable space which we are using as storage which is awesome! We had a 20' x 10' storage space that is no longer needed, the crawl space was more than enough room to put all that stuff into. I bought a mechanics dolly so getting around the crawl space is easy, it is a clean, dry well insulated space now! The crew that did the work was professional, courteous, on time and did a great job! Their estimator/project manager Jason was a pleasure to deal with from the the time he came out to look at the job to when it was finished. He has integrity and is responsive, he is trustworthy which is very important to me, I am in the mechanical contracting business and deal with sub-contractors on a daily basis so everything I have written not only comes from a personal experience as a homeowner but as a professional. You will not be disappointed in any way using this company!"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"Excellent, family-run business. I called on Monday afternoon about adding insulation and the job was *completed* within 48 hours. The estimator (company co-owner) recommended reasonable solutions and did not try to "sell" me on things I didn't need. The installers were very courteous, showed up early, cleaned up well, and even put my stuff they had to move right back where they found it. I wish I called them years ago. Very pleased with this job and company."
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.
