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.

Professional preperation and hard workers. The finished cleanout/insulation job looks great! My house feels cozy like a Home is supposed to feel.

Lake Atitlan Insulation did an excellent job in my attic. They removed the old insulation, installed a solar attic vent, replaced the bathroom vent duct, and added new blown-in fiberglass insulation. They also installed radiant barrier on all the attic roof rafters. The work was completed professionally and thoroughly.

Moisture around our foundation was causing problems. Their exterior waterproofing solution and interior drainage fixed everything. No more standing water.

Walter and his Lake Atitlan Insulation crew were amazing. I would hire their services again in a heartbeat. A couple months ago, I discovered that my home had a severely under-insulated attic and an uninsulated crawlspace. That explained the $400+ monthly heating bill I got last winter. I had several companies come to give me quotes to resolve my insulation problems. Lake Atitlan not only delivered competitive prices but also were unmatched in their professionalism! As a bonus, they are qualified by PSE for rebates, which helped with the bill and spoke to their reputation for quality and transparency. I attached the before/after photos that Walter provided to me. Everyone in the crew is very trustworthy, friendly, and hardworking. They paid great attention to detail and made sure everywhere they went was covered in plastic to make sure debris and contaminants were not spread throughout the home. I really appreciated that. In the last two months, I've been collecting energy usage data to see how much the new insulation impacted things. Given the same average monthly outdoor temperatures as those of the previous year and the same usage behaviors, I'm seeing a reduction of 10-22% in the amount of gas used to heat my home (it seems that the colder the outside temperature, the bigger the reduction). If you're looking for energy savings, look no further than Lake Atitlan Insulation!
