"I am extremely happy with AJ's service, start to finish. We initially reached out for an estimate at the beginning of 2015. A representative came to our house to explain all the different products as well as pricing and timing. I had reached out to 2 other companies before hand but was not comfortable their high pressure selling. AJ was very patient with us regarding our timing and budget. I received an estimate on the spot and was able to take my time to review and get back to them. We scheduled the work for May and was able to have 7 Windows removed and replaced in only a few hours. We are very impressed with the quick respond time, professionalism and quality of work including cleanup. We plan on using AJ to replace the remaining Windows as well as a sliding glass door in early 2016.

"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

This points to a climate difference between the inside of your home and the outdoors. While common during peak cold days, frequent icing inside your storm door points to excess moisture being trapped between your entry door and storm door. In most cases, this can be fixed by updating worn weatherstripping or addressing gaps that are allowing warm, humid air from your home to get into the space between the doors.

An interior French door should last you anywhere between 30 and 50 years, while an exterior French door unit will last around 15 to 30 years on average. Exactly how long your French doors last depends on the quality of the materials you choose, with vinyl doors lasting far less time than fiberglass, metal, and clad-wood doors. Upgrading to shatterproof glass can also improve the lifespan of exterior French doors.

The job is relatively simple, but it does require some skill. When planing a door, you run the risk of splintering it if you don't do it correctly. You’ll need to remove the door from the hinges in order to properly plane it, and removing and rehanging a door can be a two-person job. While planing a door is a straightforward repair, you’ll want to ensure it’s done right to avoid damaging your door.

If you recently tightened screws to fix a loose doorknob, the issue is likely that you over tightened them. Doing so binds the turning mechanism, which will prevent your doorknob from bouncing back when you turn and release it. To fix this problem, loosen the mounting screws just a little so that the knob bounces back as expected but doesn’t wiggle. If this doesn’t fix the issue, try loosening the knob, centering it in the boring hole, and then tightening it.

Common problems include misaligned tracks, damaged rollers, and broken handles or locks.
