The team at NW Weatherization was great from start to finish. They came out and pre planned exactly what we needed and even assisted navigating the state rebates. Great customer service

Nicholas Russi★★★★★a month ago

From start to finish, working with Northwest was really easy and enjoyable. Ryan was great about explaining what was needed in an easy to understand way. Also very knowledgeable about rebates available from the various energy companies. The crew that came was very efficient, cleaned up after themselves and made a great first impression. All around good experience for us.

Elizabeth Kirkpatrick★★★★★a month ago

Had insulation added to my attic and put it the floor. Arrived as scheduled, were quick and efficient. Had some slight confusion over one detail, but it was easily clarified with one phone call so things could still move forward smoothly. And when done, they helps with completing the forms for the energy rebates which was really, really appreciated.

I had an excellent experience with All West Coast Insulation. The Job was a new crawlspace removal and instrallation of insulation bats, water pipe and heat insulation wraps and vapor barrier. The crew was prompt, professional, and kept the work site very clean throughout the project. The workers arrived on time each day, and the bid was fair and reasonable. Noe, the owner, was always available to answer my questions and listened carefully to my concerns about the new crawlspace renovation. The team, with Rubin leading the work, made sure everything went smoothly from start to finish. I truly appreciate their attention to detail and the respectful way they communicated with me. I would gladly recommend them to anyone in need of quality insulation, crawlspace work, or drywall services. If you want, I can also make a slightly shorter version so it shows in full without users having to click “read more” on Yelp or Google. That can help more people see your recommendation right away.

What an awesome job that All West Coast Insulation did in our crawl space. New insulation under house floor, tightening up heating duct work where needed and sealing and wrapping the ducts and water pipes. The crew was excellent and took great care to control dust and cleaned up after their job. Noe Ramos, owner, was easy to work with and very responsive to questions and pricing was very fair. If you need a company you can trust to do the work right, All West Coast Insulation is the place for 5 Star performance. Bill & Sue Tigard

All West Coast just left after applying spray foam to our garages vaulted ceiling and walls (hang out space renovation) and they did AMAZING!!! Noe (owner) is incredibly easy to work with; the bidding, scheduling, etc was fair and timely and the products he uses are top notch (I was worried about the fumes and lingering odor). His is crew showed up on time and ready to work (with Noe being here at the start and looking everything over at the end, as well as calling to check in throughout the day. Impressive!). They were friendly and efficient. They took the extra time to pristinely wrap the exposed trusses, windows and cover the floor. When they were finished, the garage was cleaner than when they started! The entire garage was dust free and not a speck of overspray on anything! And NO stink :)) I am absolutely thrilled with their work and am looking forward to getting our home done next! I would give more stars if possible. They went above and beyond, surpassing my expectations… and that is not easy :))

We used Josh Lowes Dr. Energy Saver to renovate our crawlspace; which included removing an existing vapor barrier and insulation, trenched in new drainpipe and sump pump, re-insulated parts of the duct system, and installed a fresh vapor barrier. Brandon, Rico, and Chandler did an incredible job installing the new drainage system and vapor barrier. These guys were very efficient and communicated their progress and look ahead throughout the entire process, offering solutions to help achieve the goals of the install. The attention to detail is very much appreciated, their work looks great and everything appears to be working as intended. Hooper and Nate performed the removal and roughed in the new system; this was not an easy job and commend them on their contribution to the project, and clearing out the ugly part of our space. Monte was a great resource throughout the process and was always very responsive, a great first interaction with the company. You can tell he has wealth of knowledge and experience, and cares about his craft. Due to complications, the work took longer than anticipated; but, every employee that contributed to the cause was polite and treated our home with respect. Based on my experience, if anyone were to be looking to have work done in their crawlspace, I would recommend Josh Lowes. It’s refreshing to have an experience with an organization that is committed to providing a quality product and meeting the needs, and satisfaction, of their customers.

From start to finish a great experience. John provided great insight into products and possible timelines. The scheduling team were able to get our project moved up due to a cancellation. Tyler and his team are great. They called to let us know they were heading out way and an approximate arrival time- which was spot on. They explained the process and made sure we knew our timeline for access to the property. They cleaned everything up and we now have a very comfortable living space.

Lou Horn★★★★★5 months ago

It was a fantastic experience! Harry and Tyler’s team explained and did everything so professional to me and my wife. We are super happy with making this choice going forward. I highly recommend Josh Lowe’s Dr Energy saver.

Hugo and the team were great. They installed insulation in my walls and did a #4 smooth finish throughout my house. The price was fantastic, the scheduling was a little wonky, but the finished product was a 10 out of 10. I am super happy with them and will sue them again.

Shane Parks★★★★★3 years ago

Hugo and his crew are absolutely top notch. We have an old 1914 craftsman that we had them do the blow-in insulation and skim coat the entire interior, including the ceilings. Honestly I couldn't be happier with the results! The level of detail and care these guys had at every point in the process was outstanding. The price was more than fair and Hugo always answers his phone as well as helps with decision making along the way. The guys are always very respectful of your house and even did a great job of cleaning up. I seriously wouldn't hesitate to refer Martin's to anyone that needs sheetrock or insulation! Thank you so much for all your hard work guys!

Jeffrey Willard★★★★★2 years ago

Hugo Martin gave me a good quote in a timely manner! He and his guys were great, fast and knew what they were doing! Finished on time, on budget and I was very satisfied with their work! They also did a quick patch job for my neighbor and she was very happy with how it turned out!

Frequently Asked Questions — Spray Foam Insulation in Hillsboro

These are the questions Hillsboro 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 5 verified Hillsboro contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Hillsboro?▼
Homeowners in mixed climates like Hillsboro, OR 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 Hillsboro?▼
For most homes in Hillsboro, OR, 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 Hillsboro, OR?▼
In Hillsboro, OR 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 Hillsboro costs $2,000–$6,000. Most Hillsboro 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 Hillsboro, OR?▼
When searching for a spray foam contractor in Hillsboro, OR, 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 Hillsboro 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 Hillsboro 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.
