"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

No, most door experts recommend against using WD-40 on sliding glass doors. This specific product can attract dirt and debris, which can build up over time and make it even harder for your door to open and close. Instead, use a silicone-based lubricant or a dry lubricant like wax or Teflon.

A few signs that you need a new door frame include: The door no longer fits properly in its frame and sticks or scrapes. You notice cracks, holes, or rotting. You feel a draft coming from around the door when it’s closed. You find yourself frequently needing to make repairs.

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. 

Installation costs range from $300 to $1,500, depending on door type, material, and labor. Repairs typically cost $100 to $500, depending on damage severity.

Adding a doggie door can allow a burglar access to knobs and locks on your door. If your pet door doesn’t come with an alarm, you can add a weight sensor alarm that will trip if anything heavier than your pet enters through it. Adding a motion sensor light to the room your pet door is in can also help deter burglars.
