Pella sliding patio doors with heavy-duty rollers, tempered safety glass, and full weatherstripping. 6, 8, or 9-foot widths.
Every sliding door project KPro takes on starts with a free 24-hour drone inspection. We document everything before we touch a single shingle, fastener, or membrane — and you get those photos and the written assessment whether you proceed or not.
Our St. Louis customers have been telling us the same thing for 6 years strong: the difference is in the details. Three magnet sweeps for nails. Final drone inspection before sign-off. Two rounds of rain test for any roofing work. Owner on-site for every insurance adjuster meeting.
