"Taz was great! He responded so quickly when I reached out for a ceiling repair. He was reasonable working within my budget. He was able to get started right away, and completed the project in less than 2 days. He's very personable and easy to talk to. He explained everything he'd need to do so there were no surprises. I'd definitely recommend him to anyone I know looking for home repairs!"

Door Repair FAQs, answered by experts

Worn-out, broken, or damaged rollers are the most likely culprit for sliding doors that can’t seem to stay on the tracks. Replacing the rollers is a straightforward repair that will help keep your door in the track and make opening and closing it easy. Once you’ve replaced the rollers, be sure to clean and inspect them regularly to keep them in good condition.

They use specialized tools and techniques, completing repairs quickly and correctly the first time.

Look for signs of advancing wear and tear. Crumbling wood, rusted hardware, or increasingly misaligned doors indicate that you should begin considering a replacement. Although the replacement price might seem high, replacing the doors as soon as you notice these issues is best. Letting your existing doors continue to deteriorate can result in costly damage to your basement and belongings.

You should generally cut between 1/8-inch and 1 inch when planing a door. If you cut off more than that, you risk damaging the door. Planing too much from the bottom of your door can cause noticeable gaps, so it’s always better to start with as thin of a section as possible and work in thin layers until your door no longer sticks.

You can use wood, metal, or plastic as a door shim, but keep in mind that wood will rot easier than the other two materials. Your local hardware store should have at least one type in stock. Alternatively, you can trim a piece of cardboard to fit underneath your door hinge and work as a temporary, makeshift door shim.
