Christian’s service was an excellent value for our money! Our crawl space had not been tended to in 34 years and his crew made it as good as new! I highly recommend Rainier Insulation Services!

Horrible drivers, holding up traffic for miles camping in the left lane doing 5 under with nobody in front of them. Slow trucks had to pass on the right.

We had an outstanding experience with Rainier Installation. Highly experienced, extremely knowledgeable, and committed to doing the job right. They handled our insulation installation with precision and care, and the quality of the work shows.What impressed us most was the communication. They explained everything clearly and in a way anyone can understand, making the entire process smooth and stress‑free. They are polite, respectful, and genuinely take pride in their craft.We appreciate their professionalism so much and will use Rainier Installation every single time we need insulation work or related services. Absolutely top‑tier.

Christian came on time for the initial inspection of the crawl space. Very polite and professional. Took multiple key photos to show me even more detail than the trash, and hanging insulation left by other professions over the years. The estimate came in lower than a different company who was planning to do Less work. The employees were also very nice, professional, and always on time. While replacing the insulation and laying the plastic barrier down, workers found an issue with one of the heating ducts. They fixed that too! Likely will reduce our heating/cooling bill now that air can flow freely. Highly recommended!

Rainier insulation has been my go to insulation contractor for several years now. As a home builder I need contractors who can do a great job as well as keep a tight schedule. Rainier Insulation has always delivered on both.

From the moment Cristian came out to do a walkthrough of my attic and crawlspace, he was on time, professional, and extremely knowledgeable. He took the time to show me photos and thoroughly explain his findings and recommendations. I originally called Rainier to inspect the crawlspace due to rodent activity, but I’m so glad he also checked the attic while he was there. He discovered a bird nest, low insulation and vent flaws that I wouldn’t have known about otherwise.In my crawlspace they replaced all of my heat ducts and did a thorough crawlspace cleaning, which made a huge difference. His crew was just as impressive. Super professional and truly went above and beyond with their attention to detail, making sure every crawlspace opening was properly sealed. I was also very impressed with the brand-new crawlspace door they custom built for me. It feels solid, secure, and perfectly fitted.Seeing the before and after photos made me incredibly happy, and I’ll definitely be sharing some photos. They completed what felt like a tough, messy job with great care and quality.I’m truly grateful to have hired such a reliable, trustworthy, and transparent company. I’ve worked with lots of contractors in the past and they’re definitely on the top of my list to refer to all family and friends. Thanks to their work, I now have real peace of mind in my home. Highly recommend! I will be using them again for sure.
