"Insulation Co (Jo Estrada) had insulation installers come to our century old house to remove old attic insulation, do a bit of mold remediation, insulate the bathroom fan exhaust, cover the two previously open gable spaces at either end of our roof, then blow in new cellulose insulation. All this took a day, and all was cleaned up like nothing happened. Polite, efficient, professional, and the price was competitive."

"Lake Atitlan Insulation did an excellent job in my attic. They removed the old insulation, installed a solar attic vent, replaced the bathroom vent duct, and added new blown-in fiberglass insulation. They also installed radiant barrier on all the attic roof rafters. The work was completed professionally and thoroughly. I highly recommend them."

"It went very well from the estimate process. Rory took the time to explain the process. As I had questions, he took the time to talk to me and explain in detail. Deb coordinated the scheduling extremely well. Among the estimates I got they were the most reasonably priced. I started out only doing the attic. They did such a good job, I decided to go ahead and have the crawlspace insulated as well by Madrona Insulation. BTW, shout out to a terrific installation crew!"

"My 1959 home with unique siding presented specific challenges on this job. Some of the plug work done was PERFECT, and much of it was not, resulting in unsightly exterior appearance and challenging sanding and finishing being required by me, the homeowner. This company COULD have done all the plugs perfectly, but chose not to do so. In addition, I had to request a receipt for the work, and I was not provided with a written copy of the verbal warranty stated by the owner of the company."

"As a member of my condo board we had such a difficult time finding a trustworthy and professional roofing company. We sat with multiple companies only to be left feeling more confused and frustrated by each of them, until we had the pleasure of meeting Elijah team at Near Me Roofing Company. They were so professional and prepared for all our questions and concerns, but what really impressed us was that they held to their word, on time tables, budgeting and most important the quality of work. I would Highly recommend this company."

FAQs for spray foam insulation projects in Sultan, WA

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.
