"Lake Atitlan insulation was professional, fast, and did high quality work for me. I would recommend them to anyone for their insulation, sealing, and drywall needs."
"The team was very friendly, professional and did an amazing job! My attic is in much better shape now and they left my whole house cleaner then when they arrived"
"The experience I have had with Lake Atitlan is best described as excellent. Every time they have been to my house they have done all I expected and even more. I am engaging them in a long term maintenance project because they were so effective. They are awesome and i will continue to work with them!"
"I had an excellent experience with Lake Atitlan Insulation! The team was professional, punctual, and took the time to explain the entire insulation process. They improved my attic insulation, and I noticed my home felt more comfortable almost immediately. The crew worked efficiently, kept everything clean, and completed the job on schedule. I also appreciated their honest pricing and excellent customer service. If you're looking for a reliable insulation company in the Federal Way area, I highly recommend Lake Atitlan Insulation for their quality workmanship and attention to detail. I would definitely use their services again!"
"Choosing Lake Atitlan Insulation was one of the best decisions we've made for our home. We had been dealing with uneven temperatures and higher-than-expected energy bills, so we decided it was time to upgrade our insulation. The team was incredibly knowledgeable and took the time to inspect our home, explain their recommendations, and provide a fair, transparent estimate. The installation process went smoothly from beginning to end. The crew arrived when they said they would, worked efficiently, and showed great attention to detail. They were courteous, respectful of our home, and cleaned up thoroughly after the job was finished. It was clear they take pride in their work and genuinely care about customer satisfaction. The difference has been noticeable almost immediately. Our home feels more comfortable, the temperature stays consistent throughout the day, and we've already noticed our heating and cooling system isn't running as often. It's reassuring to know we've also improved the overall energy efficiency of our home. I highly recommend Lake Atitlan Insulation to anyone looking for high-quality insulation services. Their professionalism, craftsmanship, and commitment to doing the job right exceeded our expectations. We'll definitely recommend them to friends and neighbors."
"This business was easy to work with & extremely professional. They treated my home with an immense amount of respect & did amazing work. I've attached before & after pics. I highly recommend!"
"The company was professional, and they took care to clean up our property when they were working."
"I had the Lake Atitlan team clean up and reinsulate our crawl space and I couldn't be happier with their work. Their bid was the lowest of the 5 that we got for the project and it was just as comprehensive as the highest bid. They we able to schedule my job the very same week and got it done in less than a full day. The space is now clean, tidy, and super well-insulated, and they dealt with the rodent issues too. The whole experience - from getting a quote to scheduling the work to getting the job done - was excellent and I highly recommend them. Really outstanding."

Stop Losing Heat and Battling PNW Moisture Problems
Is your home cold in the winter, overheated in the summer, or struggling with a musty crawl space smell?
Many Seattle homes—from Ballard to West Seattle—were built with insulation that has aged, settled, or become damaged by years of Pacific Northwest moisture. Poor insulation and damp crawl spaces can lead to uncomfortable rooms, higher utility bills, and reduced indoor air quality.
At Lake Atitlan Insulation, we help protect your home with professional insulation upgrades, crawl space improvements, and energy-saving solutions designed for the Puget Sound climate.
Protect Your Investment
Why Seattle Homes Need an Insulation Upgrade
Many homes built between the 1960s and early 2000s were not designed for today’s energy standards. Over time, insulation can lose effectiveness, absorb moisture, or become damaged by pests. The result? A home that works harder to stay comfortable.
- Rising Energy Costs Poor attic and crawl space insulation can allow heated and cooled air to escape, forcing your HVAC system to run longer and increasing monthly energy costs.
- Moisture & Crawl Space Problems Seattle’s wet climate, wooded areas, and coastal conditions create the perfect environment for crawl space moisture, odors, and insulation damage.
- Rodent Damage Attics and crawl spaces provide warm shelter for pests. We help identify entry points and restore damaged insulation systems.
