Marvin was very helpful and guided us through our attic moisture problem. We highly recommend him for any insulation work.

I hired Lake Atitlan Insulation on the recommendation of a friend to insulate a large family room that had been completely destroyed. I really appreciated that Marvin came in person to see the site and estimate the scope and cost. During the initial installation, an issue arose after the crew left. Seeing that I wasn't satisfied, they sent a crew back to fix it the next day. I am very pleased with the results and happy I made this investment in my home. Marvin was fantastic to work with, and the crew leader, Delfino, was extremely courteous, professional, and thorough in our home.

These guys were great!! Marvin and his crew were excellent. I would recommend them to any one. They replaced all my ducting, installed new insulation and put a moisture barrier in the crawl space.

We had Lake Atitlan Insulation remove our old insulation and replace it with R-38. I enjoyed working with Nanni from the initial meeting to the final step of installing the insulation. Very knowledgeable lady and truly exceptional customer service. A highly recommended insulation contractor.

Lake atitlan insulation did a professional job insulating our rental in maple valley. Their crew was prompt, communicative, and detailed about their work, even letting me know about things beyond their scope of work. I would do them again in a heartbeat.

A friend recommended this family company for insulation and I was left very satisfied I highly recommend them they made the process delightful.

The lake atitlan, insulation team just finished replacing our old blown in insulation in our attics with white R-38 rolled batt insulation. Overall, we were very happy with their work and attention to detail. Everything was spotless when they left. They were also a few thousand dollars less expensive than a bid we got from a larger local chain. The old insulation was blocking the soffit vents (under the gutters) allowing moisture and black mold to develop on the underside of the roof sheeting. First, they built a plastic tunnel from the front door up to the upper attic access door in the top of a closet near the bedrooms. This prevented any debris from the job filtering into the house as well as protecting the carpet. Next, they removed all the old insulation with the assistance of a giant vacuum. The black mold on the underside of our roof sheeting was treated and the new insulation installed. It now looks like a field of freshly fallen snow up there and no blocked vents.
