"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

Many doors can be cut to size, but it depends on the door material. Solid wood doors are relatively easy to trim to a specific size, while hollow core and metal doors are trickier and can usually only be shaved down a little before you risk damaging them. If your door needs a lot of adjustment, it's best to order a custom size or have a pro do the resizing to make sure it holds up over time.

Some of the most common problems with door closers include leaking hydraulic fluid and loose or missing screws. They also can cause damage to door frames and hinges over time if not properly installed or maintained. This might look like warped doors, misaligned hinges, or even shattered glass doors from improper closure. To avoid having to pay the cost to replace a door frame, you should monitor your door closer and ensure it’s working properly over time

You can fix a door frame without replacing the whole door by repairing the impacted areas with wood filler, patching, or replacing components. You’ll need to uninstall your door to repair the frame and then reinstall it once you’ve completed the repair. However, if your door frame has severe structural damage, it might be more economical and safe to replace the entire door.

Over time, latch components may wear out or get grimy, leading to this problem. First, check for dirt, dust, or debris in the latch mechanism to ensure smooth operation. Use an aerosol duster and lubricant to clean and loosen. You may also need to tighten the screws in the component, adjust the strike plate, or replace the lock. If none of these steps resolve the problem, consult a professional locksmith.

The cost of folding patio doors is higher than the typical patio door cost because of their size, complex mechanisms, and additional hardware needed to operate them. These doors may stretch as far as 18 feet, require specialized installation from an expert, and have many more moving parts that could malfunction if not installed carefully.
