"Insulation NW did a great job on my attic insulation install. Both the estimator and the installation crew were knowledgeable, polite and they cleaned up after they finished. The price was most excellent as they included the PSE rebate in their quote."

"Great job! The project of getting spray foam insulation installed under our house went exceptionally well, from start to finish. We got an estimate the same day we called, the install was done well, at a good price, was completed on time. We are very happy with the staff and the work. Thank you, PNW Insulation!"

"I called Lake Atitlan Insulation for an inspection of my crawl space because I wanted to move forward with an encapsulation. Juan Daniel was very professional and took the time to explain the entire process clearly from the beginning. After the inspection, I received the estimate on the spot, which gave me the confidence to move forward. They installed a new 10-mil white vapor barrier, insulation between the floor joists, foam board insulation along the concrete walls, sealed the crawl space vents, and installed a dehumidifier to control moisture. Juan Daniel also explained why sealing the vents is so important in an encapsulation system. I highly recommend Lake Atitlan Insulation. They are very professional and did an excellent job."

"⸻ Review for Insulation Pro I highly recommend Insulation Pro. After receiving multiple bids for mold remediation — each identifying a different problem and proposing a different solution — I was left uncertain about the real issue and cautious of high-pressure sales tactics. Insulation Pro quickly stood apart. They accurately identified the true problem, explained their findings clearly, and never once applied pressure or attempted to upsell unnecessary services. Every one of my many questions was answered with patience, clarity, and genuine understanding, which gave me complete confidence in their professionalism. Their cost was appropriate, reasonable, and well justified given the quality of their work and the results delivered. In today’s world, where trust in service providers can be difficult to earn, Insulation Pro exemplifies integrity, transparency, and expertise. They addressed the issue efficiently, went above and beyond my expectations, and delivered results I could t"

"I hired Acorn Attics to insulate my house and I couldn’t be more happy with their work. Phil and his crew were on time, friendly and incredibly hard workers. He worked with me on scheduling and made sure to keep our project moving even when we had a setback with another repair. I highly recommend them. They will get the job done. Thank you Acorn Attics and Crawl Spaces!!"

"The job was done timely. They went out of their way to make sure everything from replacing the insulation to a thorough rat abatement was done right and explained everything to me. They even installed some bird spikes for me."

"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!"

"The workers were on time. Very efficient. They did a blower door test and found the air leaks and insulated these areas. Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

FAQs for batt, rolled or reflective insulation install or upgrade projects in Belfair, WA

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
