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.

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 will be recommending this company going forward. THANK YOU to GABE, IVAN & ROBERTO! You can tell they take pride in the work!

Brendan Slattery★★★★★a year ago

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!

Aaron★★★★★3 years ago

I hired Environmental Insulation and Contracting to remove insulation and re-insulate my crawlspace after the big flood of 2021. Blake was great to deal with during the quote and scheduling process. The crew came out quickly, the re-insulation job looks great, and the price was very competitive. I hope I don't need to re-insulate my crawlspace again anytime in the near future, but I wouldn't hesitate to use them again. They really helped out a lot of us in the north county!

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.

Peter Guillozet★★★★★5 months ago

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.

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.

Insulation and gutter job on fire rebuild was done well by polite and conscientious workers. I recommend this company

Timothy Jacobs★3 years ago

Disappointing gutter installation. Master Insullation installed three gutter sections on my home on Lopez Island. I specified in my request for a bid that my roof would require gutter wedges due to the angle of our roof edges. Master Insullations estimate came back saying yes they would install gutter wedeges. I accepted the bid. The gutters they installed did have wedges, however the angle was much smaller than the angle of my roof edge. The gutters droop down. I requested that they replace the wedges with the correct angle. They replied that their supplier doesn't make wedges with a greater angle, and a larger wedge wasn't in their bid so they would not correct the installation. I researched gutter wedges on the web and found larger ones on Amazon and other suppliers. Several emails and phone calls later the best they would do is come out and swap the wedges, but I'd have to supply the wedges at my expense. I feel like a customer shouldn't have to be an expert on gutter wedge angles and supply to get a quality job.

Frequently Asked Questions — Spray Foam Insulation in Bellingham

These are the questions Bellingham homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 7 verified Bellingham contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Bellingham?▼
Homeowners in mixed climates like Bellingham, WA typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Bellingham?▼
For most homes in Bellingham, WA, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Bellingham, WA?▼
In Bellingham, WA and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Bellingham costs $2,000–$6,000. Most Bellingham homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Bellingham, WA?▼
When searching for a spray foam contractor in Bellingham, WA, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Bellingham contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Bellingham for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
