There was a leak around the chimney, and I needed an emergency repair. I used Midwest Remediation for the job because they were the only guys that could come the same day I called. I was pretty happy with their service, especially with their promptness. I supplied the shingles, and the next day, they came back and placed the appropriate material needed since the furnace was near the ventilation. Although they didn't come back after I wanted some more caulking to be done, I'm still satisfied with the repairs.
