What Homeowners Say
After we leave
We found mold in our crawl space during a home inspection and didn’t know where to start. Sadeq’s team explained exactly what they’d do, how long it would take, and what it would cost. The clearance test came back clean. We closed on our house two weeks later.
- Sarah T., Kent | Mold Remediation
I called three companies about attic insulation. Two wouldn’t give me a price until they “came out to assess.” Green Attic sent me to their calculator and I had a number in thirty seconds. The final quote was $200 off from the estimate. That’s it.
- James R., Mountlake Terrace | Attic Insulation
Rats had been in our attic for months. Green Attic sealed every entry point, removed all the contaminated insulation, sanitized the space, and installed new blown-in. The whole project took two days. Our energy bill dropped $60 the next month.
