"WOW they did a fantastic job! They got here on time and took their time getting the attic prepped to seal air pockets before they sprayed the insulation in the attic. They also fixed spots in the crawl space before putting down a new plastic vapor barrior. The work that they did made a major difference in the warmth in my home. I am very please and would diffentaly recommend them."

"They were very professional and the quality of work was excellent. They stapled depth indicator strips on the attic rafters to ensure proper fill. When they found gaps around canned lights and brackets, they suggested filling them in with foam. I would definitely hire them again and recommend them to family and friends."

"We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor."

"I’m very satisfied with the insulation work performed under my house. My home is now toasty warm on my feet. Phillip and his worker showed up on time, went about their work and cleaned up the mess created in the process. I am greatful that I found such a competent company."

"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."

"Erick with AG construction came to my rental a week ago. He had the proper equipment to crawl under the house and determine what I needed to fix broken heat pipe, replace vapor barrier and replace insulation from a plumbing leak. I also had signs of rodents. He gave me a bid that was reasonable and was able to have his team on the job within a week. I stopped by as the work was being done and saw old insulation in bags headed for the dump. The area was left clean and his photos of the job look great. This is a very professional company and I would use them again for any crawl space work."

"I started this project months ago to completely reinsulate my attic with none of the experience; let me tell you, not a beginner-friendly DIY project. You gotta be Spider-Man to crawl around in my attic space, which I did numerous times. My friend and I spent 3 hours blowing insulation into the attic one morning, making our way through 12 bags of cellulose. After that I called Wallet-Friendly and I'm so glad I did. Martin reassured me with his confidence and plan that they would do a much better and safer job than I ever could. Plus they live up to their name! Two days later Martin and Gary distributed 58 more bags of cellulose in less than 2 hours. But I didn't order enough and we needed more! The cellulose arrived two days later and so did Wallet-Friendly Insulation to finish the job. Just in time for another heat wave!"

FAQs for spray foam insulation projects in Belfair, 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.
