Cleaner crawl spaces in Sunnyvale
Many Sunnyvale ranch homes sit on raised foundations, over crawl spaces with their original insulation and a vapor barrier that's long past its best, if there is one at all. It's the part of the house nobody sees, so problems there can go unnoticed for years.
Our crews work under homes all over Sunnyvale, including Cherry Chase, Birdland, Raynor and Lakewood Village: cleaning, sanitizing, new vapor barriers and under-floor insulation.

What we see in Sunnyvale homes
- The houses
Sunnyvale grew fast in the 1950s and 1960s, so most of its homes are ranch houses and tract homes from that era, including several Eichler neighborhoods, with older bungalows around the Heritage District.
- The weather
Sunnyvale lives up to its name: long, warm, dry summers heat attics for months, and that heat works its way into the bedrooms below.
- The wildlife
Fruit trees left from the valley's orchard days, ivy and mature landscaping give roof rats food and shelter in Sunnyvale backyards.

“Joey and his crew arrived on time. They were very professional and considerate to our needs. We needed our old insulation swapped out and have our attic and crawl space rodent proofed. They did an amazing job at doing so. He was considerate enough to take pictures of all work completed and presented me everything.”
“After 19 years, my crawl space was a disgusting mess due to being inhabited by rodents. Jay came to my home to make an inspection and recommendations. He showed me photos of the problem and explained exactly what was needed to be done. Two weeks later as planned, Wais came out with the crew right on time. When the job was completed, I was again shown with photos exactly what was done and was beyond satisfied with…”
“Ahmad and his crew did a great job to complete the work. They were very efficient. They removed old insulation, sanitized and put new insulation in the attic and cleaned out the crawl space. Also mended some torn nets. It was also easy to get an estimation and schedule the work.”
