About Certified

Gutters, garage doors and windows all fall within the listed work of Certified, an exterior contractor in Columbia, MD. It has been trading for 42 years. Its staff numbers 15 people.

Roofing is on the listing. Roof work ranges from replacing a few missing shingles or resealing a vent to a full tear-off, and the age of the roof and any visible leaks inside help a roofer judge which one you need. The profile adds window installation to its main category.

Window installation is part of the work Certified does. Interior trim, paint touch-ups and disposal of the old units are details that vary between quotes, so ask what is included once the new windows are in.

Its posted hours are Monday to Friday 8:00 am to 4:00 pm; weekend times are not shown. Living in Clarksville, Fulton and Ellicott City rather than Columbia itself? Include your town and ask.

Share any HOA or historic district rules with Certified before choosing materials or colors. A contractor can only quote accurately once those limits are known, and some approvals take weeks to come through. Clear a path around the work area outside, including vehicles, planters and patio furniture, before the crew arrives.
