"The company was quick and professional. My only issue is that the discussion, questions and agreements I had with the estimator did not align with the work the insulation teams did."

"I highly recommend Jason and Craig there at Mold Blasters. They did and absolute phenomenal job on reinforcing the wall in my crawl space that had begun to bow. They also encapsulated the crawl space which makes me feel so good and reassured that no mold will now form. I cannot say enough about this company. Jason is very honest and follows thru with what he says. You don't get that often these days. I would give more than 5 stars if I could. Good honest work. Thanks again Jason and Craigð  ¥"

"Talkedto Steve at the home and garden show and set up an appointment for an estimate.
When he came out, he told me right up front that they were pretty backed up due
to the bad winter. I was fine with that and set a date that was good for both
of us to have the work done. They called the day before to remind me of the
appointment and showed up on time and did the work in one day. They did a great
job, cleaned up after themselves and you couldn?t even tell that they had
popped off the siding to drill the holes for the insulation.
