I had a fantastic experience with Insulation Pro Inc for my attic insulation project. From start to finish, everything was handled with professionalism and care. Sam, in particular, was outstanding. He was not only incredibly knowledgeable but also took the time to walk me through the entire process, answering all of my questions with patience and clarity. He made sure I understood the benefits of the insulation being installed and what to expect. On the day of the installation, Sam and his team arrived on time and worked efficiently while being respectful of my home. They prepped the area carefully, completed the job quickly, and left everything spotless once they were done. I was especially impressed with their attention to detail and how thorough they were in making sure every corner of the attic was properly insulated. Since the insulation was installed, I’ve already noticed a big improvement in the comfort level of my home, especially with temperature regulation. It’s clear that they used high-quality materials and took pride in their work. If you’re looking for a trustworthy, reliable company for your insulation needs, I highly recommend Insulation Pro Inc—and definitely ask for Sam! He truly made the entire experience stress-free and delivered results that exceeded my expectations.
This team was incredible! After multiple quotes, we ended up choosing this team because of their pricing, transparency, and attention to detail. Eric and Omid did not use any pushy sales tactics or try to give us silly customer discounts. They provided honest assessments and gave rationale answers for the problems in our home. We ended up getting all new insulation in our attic and crawlspace and mold remediation as needed. While assessing the crawlspace and completing that part of the project, they found issues with our sump pump and drain system in the crawl space which needed addressed to fix the moisture issue. The team was so efficient and conscientious in all their time within our home. We felt safe having their team working at our home while we were at work and appreciated all the real time updates Eric provided us with. They were extremely accommodating of our needs and requests, and even respectfully and graciously appreciated the feedback we offered them during one project roadblock. Would recommend this team to everybody needing work done! Thank you so much! 🙏🏼
I recently hired INSULATION PRO and I'm very satisfied with the work they did. They have a great team and I highly recommend them!

Tom was very friendly and straightforward with the inspection, detailed the problems, replacing procedure, and warranties. The decision was made fast with a reasonable cost. 5 stars rate to him. Ronny and his crew are a fantastic hardworking team! They carefully setup their working environments to keep around clean. Then removed all the old insulation, laying up the new ones. When I realized the very small area need to be fixed, upon very tight schedule, Ronny’s crew came back fixed nicely. Yes, Rate Ronny and his crews all 5 stars. The company office has a super service lady Lorrie. She sent the before and after photos, make an inspection schedule, helped the fixed problems… She is friendly, patient, and quickly to resolve the problems! Definitely, Rate her 5 stars. The inspector, Jose, was done a good job and help to resolve our small area problem, Rate him 5 stars too. By my experience, I’m satisfied with this company with good leaders and hard-working teams. I would rate it 5 stars and recommend it to my friends.
At some point over the winter, rats got under our house and shredded everything in their path. I got several bids for the work, not only did Super Attic Solutions offer the best price but they also offered better quality materials for the project, going with them was a no-brainer. Joey who did the appraisal was professional, polite and knew his stuff, joy to work with. They got me scheduled within a week and I got Ricky as my project manager. I’ll say they knocked it out of the park, the crew busted their butts all day and the end result was day and night. The transformation was mind blowing I had no idea how bad the damage was until Ricky and his crew were finished. Our house was built in the 40’s now we have a crawl space and insulation comparable to a new build! Super happy with the results from Ricky’s crew, their professionalism and hard work did not go unnoticed. I highly recommend this company for any insulation-related project. If you get Ricky as the project manager, rest assured the end results are well worth every penny! The company as a whole made this nightmare situation seem manageable and I really appreciate the work! Few Before and after photos below, mind-blown!
This company took care of our attic reinsulation, duct replacement, and rodent infestation all at once. The crew was extremely competent, neat, and on time. A special thank you to Tomer for his exceptional work on the rodent proofing; his thoroughness gave us great peace of mind. The entire process was smooth, and the improvement in our home's air quality and temperature is remarkable. A fantastic job from beginning to end!

PNW Roof & Crawlspace Insulation removed our very old cedar shake roof & installed new high quality metal roof; took off and re-installed our gutters when finished replacing the roof; cleaned out, removed and re-insulated, re-screened, & installed vapor barrier in our crawlspace; cleaned out our attic, & removed & replaced our attic insulation, re-screening all the vents, and removed old fascia and replaced it with new, repainted fascia when the roof installation was completed. They took away all the old materials/garbage, and did a thorough sweep of the premises with a magnet roller after removing all trash materials. When we called for an estimate, PNW answered right away, and their estimator was at our house very quickly.Everyone at PNW couldn't be more friendly, courteous and capable! All the work was done quickly, safely, and on time. Everybody always has a smile on their face, and a hard working, can-do attitude. Their prices are very competitive, and communication was always nothing less than excellent. Their printed estimate and handout given at the time of estimation explains clearly and in detail the work to be done, and the specific type and brands of materials that will be used. All safety procedures, final cleanup procedures, and prices are also listed in detail. We work in the construction trade, and we are impressed. Thanks PN for the wonderful job!!
Alfredo, Ana, and the PNW Roofing crew have been timely, responsive, and super helpful to work with. We had a leak in our roof, Alfredo came out the next day, assessed the issue, provided multiple potential solutions at varying price points and levels of disruptiveness, and was overall very knowledgeable. We were able to have our issue fixed within the week. We have also done roof cleaning and moss treatment on our roof - it looks sparkly and new! We would happily book any roofing needs with this crew again.
I recently used PNW Roofing for a full replacement in Edmonds, WA, and overall, I am very satisfied with the results. The team was impressive, completing the entire process—from tearing off the old roof to installing the new 30-year GAF system—in just 2.5 days. Working with Ana and Alfredo was a pleasure; both were patient, professional, and friendly throughout the project. My main advice to others is to be diligent during the quoting phase. The initial estimate felt a bit inflated, though they were willing to negotiate and eventually price-match. Also, keep a close eye on the "extra" costs in the contract. Additional work, such as replacing plywood or fascia boards, can be expensive. For instance, unpainted fascia boards cost $120 each, with painting adding another $100+. However, given the high quality of their work, their quick response times, and the fact that many competitors are currently overcharging for profit, I would recommend PNW Roofing.

Specialty Insulation NW did a great job on my project. From my initial contact with Corey, to the installation team, everyone was a pleasure to work with. I almost didn't call these guys because I thought they did only foam. They do all kinds of Insulation. They used mineral wool and fiberglass on my project. Francisco and the other installers were all friendly and patiently answered any questions. I had spoken to other companies for quotes, but no one impressed me like Specialty Insulation NW. They were not my cheapest bid, but i am so glad I used them. They know their product well, can answer all your questions, respond promptly to questions, and have some of the best customer service I have experienced in the construction field.
Thank you Specialty Insulation NW, LLC for helping insulate this shed that we’re turning into an outdoor kitchen. The crew was punctual, clean and did great work! Corey and the Pam were easy to work with and communicated well throughout the process. I think the spray foam is a great way to go when insulating a structure and this is the company I would recommend to do it!
We had to get our crawl space cleaned and replace the old insulation with new. It took two days. I didn't know it would scare my one dog so much on the first day. On the second day I explained my situation to one of the installers Ramiro. He bent over backwards to help reduce the noise by keeping the compressor on the side of the house where my dogs weren't staying, outside. That was a big help and they really did their very best to keep the noise down while doing a great job.

Attic Doctor helped with mold removal in my attic, and the whole experience was excellent. Jay and his team were great to work with from start to finish. Jay was very responsive and clearly explained the issue and the steps they would take, and the pricing was much more reasonable compared to other companies I contacted. His team worked efficiently, and did a thorough job. They were professional and respectful throughout the process. I also really appreciated that Jay provided detailed before-and-after photos, which made it easy to see the original condition and exactly what was cleaned and removed. I’m very satisfied with the results and would definitely recommend Attic Doctor.
Attic Doctor did an insulation job (and air sealing) at my home and I couldn't be happier with the results. They were communicative throughout the entire process, keeping me informed and answering all my questions clearly. What really impressed me was their integrity. During installation, they discovered several exhaust vent ducts that weren't up to code. Instead of charging extra to fix it, they corrected it for free since they hadn't caught it during the estimate. This kind of honesty is hard to find. The work itself was very thorough and well-done. The crew was professional, respectful of property, and left everything clean. Riley and Jay checked in often during the job to ensure things were being executed correctly. They clearly take pride in their work. If you need attic insulation in the area, I highly recommend Attic Doctor! They combine great quality work with honest business practices. I would definitely use them again.
After doing our due diligence we chose Attic Dr to remove/clean debris from the attic and crawl space, remediate some areas that had mold, remove all old insulation and install new R-38 attic insulation. Both attic and crawl space had all openings sealed and rodent traps were set in place. From start to finish we were very pleased with their process. Pictures of the entire attic and crawl space before, during and after the work was done were reassuring. I would not hesitate to recommend this company. They were professional, responded to any questions we had in a timely manner and left the area around our residence neat and tidy.

I had the best experience with this company. From start to finish, they made everything easy and stress free. The crew showed up on time, explained what they were going to do, and really knew their stuff. They sprayed foam in my crawlspace and the results were noticeable right away, the floors feel warmer, I don’t feel the drafts anymore, and the space looks super clean. I’d give them 10 stars if it was possible.
We had a great experience using USA Insulation of North Puget Sound! Every step of the process was professional and easy. We worked with Max (owner/coordinator), Jason (estimator), and Jaime (installer). They all listened to our needs and completed the job quickly - and it looks great! Highly recommend working with this team!
Absolutely a great experience from Max bidding it to his crew installing the products. I won’t forget their phone number as I’m sure my friends and family will need there services. Prompt on time. Clean up was spotless just all around Professional Company.

Got Cascadia Spray Foam Insulation to take care of my in-laws place up in Seattle. The house was older and had some serious drafts, especially in the winter. The crew came out, did a full walk-through, and explained exactly what they were gonna do. Super professional and easy to work with. The difference after the spray foam was like night and day. The house stays warm now without the heat running non-stop. My in-laws are beyond happy and I’m glad we called these guys. Definitely recommend.
Finding this company made my cousin's day. He needed a reputable spray foam insulation company for his business in Seattle and I was able to recommend this company.
Thank you for having all your information and services clearly outlined and updated, it really helps when searching for service providers

Ernesto and his team helped us clear out an attic to allow us to do our remediation work and had the customers new insulation installed the day we finished our work. They were fast and thorough, we love working with them!
Cesar replied to my phone call quickly, sent over a proposal within a few minutes and had a crew out doing the work just 2 days later. EXCELLENT SERVICE !
Friendly nice people. Pacific Partners is up the stairs marked BDI. Or go around the building counter clockwise to the warehouse at the East end of the building.

While unloading a large amount of heavy asphalt shingles at the Algona Transfer Station two insulation Contractor employees freely and without being asked volunteered their assistance. It took them all of five minutes to each grab an end of the tarp I had laid out under the shingles and dump what would have taken me a full hour to unload. I wanted to publicly thank these two young gentlemen who not only saved me an hour of back breaking work but also for restoring my faith in humanity. Well done and whoever you are I wish you the very best.
Excellent customer service, very knowledgeable and did an exceptional installation. Highly recommend Magellan Insulation! --Brandon 2/5/15

Insulation and gutter job on fire rebuild was done well by polite and conscientious workers. I recommend this company
I have been using Master Insulation for over 7 years. There prices are always the best and service is better then most. Would highly recommend.
Terrible drivers, literally cut off a bunch of people despite knowing the lane they were in was turn only. I'll never do business with a company who acts like nobody else's time matters more than theirs.
