Spray Foam Insulation in Bellingham, WA

These guys are legit! They showed up on time as scheduled, worked very quickly but the work still looked high quality. The bid did not change one penny. My crawlspace was very skinny in some spots and they finished it perfectly to every corner. They were efficient, professional, clean, fast and competitive. I would definitely recommend Insulation Co for your job.

The crawl space to my property had not been addressed in more than 20 years. While having my crawl space inspected, the inspector stated he noticed rat feces and the vapor barrier not fully intact. I reached out to this insulation company and not sure what to expect. The team arrived as scheduled and immediately began to work. Four employees worked in my crawlspace nonstop. They were all business from start to finish and very much organized. Complete professionals in completing the task. Hi would definitely hire this company again to complete Like work. Oh, the price for completing the work was fair.

We recently hired Jo and his team to complete insulation work in our attic, and the experience was exceptional. They quickly identified several issues: including rodents, mold, and roof leaks and guided us through the entire remediation process. Jo also helped us find reliable subcontractors, ensuring the work was completed thoroughly and on time. They treated the mold, added cellulose insulation to the attic, submitted the PSE rebate and delivered high-quality results at the most competitive price among all the bids we received. Jo and his team were professional, responsive, and a pleasure to work with. Thank you for everything, the attic looks great now.

Lembcke blew in attic insulation and insulated a side room. They were the best priced and did a great job. My wife even noticed how thorough of a job they did on the side room. Thanks Lembcke!

I hired Proficient Insulation to apply spray foam to the ceiling of a shipping container to stop condensation raining inside. Excellent communication and quick to answer questions. Mario arrived on time and was very professional. He worked efficiently and left everything clean and neat with no overspray. The container had 3 roll-up doors that roll up close to the ceiling. Mario was able to apply insulation in the tight space above them without getting it too thick where it would interfere with the doors opening. I'm very pleased with the result and happy with the price too.

I own GF Construction, in Bellingham. Mario and crew are excellent. I had a small, older home with around 12" of crawl space. Mario and crew hand dug, and hauled out the soil to get to 18" crawl. They set 6 mil vapor barrier, and perfectly insulated the floor. They also vacuumed the old insulation in the attic and blew new to proper R value. They do great work at very competitive pricing. I highly recommend Mario and Proficient Insulation for all of your insulation and crawlspace needs.

From start to finish, Mario and his crew nailed it. First, cost was absolutely fair. Second, Mario was super knowledgeable regarding our needs and permit requirements and was able to solve all of the special needs our building had, like a spray foam ceiling. Third, they are fast! We would hire Mario and Proficient Insulation again in a heartbeat and definitely will for any future projects. This was probably the most painless of the many steps involved in our project.

Fast, reasonably priced, and high quality work. Cory was very informative throughout the process and I appreciated their flexibility with scheduling. Highly recommended!

Look no further if you’re trying to find the highest quality insulation company in Whatcom county. We had a rodent issue and the old insulation under our home had been installed with wire stays, which we learned aren’t very reliable. Over time, between the old rusting stays and rodent activity, the insulation had fallen out all over our crawl space. I’d started trying to rehang the insulation myself, but soon realized it was too soiled and damaged. Plus, our 1920’s home has a shallow, non-standard crawl space, so it was just not a one-person affair. I decided to call some companies for estimates. We started with foundation “specialists”, because our crawl space is non-standard due to the house age and construction. Several companies made it clear they weren’t interested in this small of a job, our house being under 900 square foot. One large company’s estimator (with advertising that says they have specialists and engineers for any problem) told me he’d get back to me with an array of options, but instead ghosted us. We started calling insulation companies. The first larger company we had out, said they’d do the work once the space was certified, which wasn’t going to happen given foundation repair outfits wouldn't respond. Another larger local insulation company told us we should just close the space up as best we could, rodent soiled with useless insulation hanging, and forget about it. Fortunately, I’d made an appointment with the Insulation Company for an estimate. Christian came out, looked the space over and told me they could clean out and re-insulate our crawl space. I was astounded and relieved that someone could finally help us with our situation. Christian was kind, exceedingly professional and followed through with a written estimate in short order. He specifically told me it was his goal to provide solutions for his customers and not just walk away from a difficult problem. The price for the work was competitive and affordable. We couldn’t schedule them soon enough. Not only could the Insulation Company help us, but they sent out an incredible crew, Dani and James, their insulation specialists. Dani and James were exceedingly professional, clean and competent. They communicated about the scope of work, then started with quickly and efficiently clearing the old insulation and vapor barrier, thoroughly cleaning up after themselves as they went. The new materials were installed with care and concern for our older non-standard 1920’s home. Even when they discovered the joist spans were odd sizes in areas, they adapted materials to work in the space. There’s just no one else we’ll call going forward for insulation or pest issues. We’re grateful for their professionalism, hard work, affordability, and most of all for putting our crawl space to rights. Thank you all so very much!

We used the Insulation Company to put in new insulation in our attics and crawl space. They also did some additional crawl space repairs. Cory and his team are amazing!!! Throughout the entire process communication was excellent and the work done was perfect. Everyone went above and beyond. I highly recommend the Insulation Company!

FOR TRUCK DELIVERY. Very nice workers, fast and helpful. The dock is set up for a blindsided but not crazy hard. Get out and look and you will be fine. The workers even offered to guide me back.

Coast Insulation insulated my garage roof on Orcas Island using a combination of closed cell spray foam and fiberglass batts. When I asked them to touch up a few areas of the foam, they did so willingly and at no additional cost. They did excellent work and I would happily hire them again. I‘ll definitely recommend them to others.

Absolutely great service start to finish , Amy keeps you informed on schedule, bids are clear and clean from builder and home owner perspective, with good insite on basic bid and extra ideas for sound control custom to your project. Crew shows up on time and gets the job done in timely manner , cleans up and leaves site looking like it was if not better than when they got there.

had such a great experience with this company from start to finish. Katie, the woman in the office, was so friendly, clear, and easy to work with. She explained everything upfront, communicated so well, and honestly made me feel comfortable booking with them in the first place. Then Bryan J came out to look at my attic, and he was just as amazing. He was professional, honest, and genuinely cared about what was best for my home — not just trying to sell me something. It truly felt like working with a company that looks out for you and treats you with respect. As a homeowner, feeling safe and taken care of means a lot, and this team absolutely delivered. The whole process was seamless, and I can honestly say this is the best company I’ve ever worked with. Highly recommend!

Devyn provided much-needed expertise to help us complete our new house. He is knowledgeable, prompt, courteous, and I would not hesitate to use Environmental Insulation and Contracting, LLC for all insulation needs.

During the inspection of our home, we encountered an issue with the insulation around our HVAC system. We called Environmental Insulation and Contracting LLC. Brian came out to review the issue. He answered my questions and concerns and then scheduled a date and time to address the issue. The issue was addressed with a quick turn around and we are 100% satisfied with the work that was completed. I would highly recommend Environmental Insulation and Contracting LLC! THANKS Brian!
