"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

If you don’t know which door sweep to buy, look into getting a strip or bristle sweep. They’re easy to find at the store, work well for most doors, and the simple installation is DIYable. Before buying one, measure your door width and make sure the one you want is long enough. Most door sweeps are 36 inches long, and you can cut them down to size with a hacksaw.

Lock picking is a relatively subtle method of unauthorized access, making it hard to detect. But there are telltale signs to look for. First, look for scratches or tool marks around the keyhole or the lock's surface. Also, check for loose or misaligned components, like a wonky strike plate, which could indicate tampering. Consulting a locksmith or security professional for an assessment can provide valuable insights, too. Investing in high-quality locks and considering additional security measures, like security cameras, can help deter potential intruders and enhance your overall safety.

The cost to repair a sliding glass door is $225 on average. Your total cost could be as low as $50 for a new door handle, or $635 or more for replacing broken glass in your sliding door. Not only does the type of repair impact the total cost of this project, but the location of the door does, too. For instance, the cost to repair an exterior sliding door costs more than the repairs of an interior sliding door, like a shower door.

Yes, you can install a steel door without replacing the frame, depending on the condition of your existing doorframe. If the current frame is in good condition, a steel door that’s the same size as your current door should fit the frame. However, if the frame is damaged, warped, or not properly aligned, it’s better to replace both the door and the frame. This way your steel door will be more secure and offer better insulation.

It's not uncommon for the thermal seal of double-paned windows to break down, but the repair is best left to professionals. The cost to repair a window's broken seal ranges from $70 to $120.
