"After reading the excellent reviews of Goodfellows Windows, I reached out to the company for a quote. Gary, the owner, came to my house and quoted an amazingly affordable figure. We decided to replace every window in the house including a large bay window. We also replaced a sliding glass door off of our family room, a outside door leading to our deck, and a front door unit consisting of a door and a glass window with internal shades. Because of Covid 19, our order took longer than projected. This was not the fault of Goodfellows. Our sliding door, deck door, and front door were put in first. The workers, Phil and Orlando took meticulous care to make sure everything fit perfectly. The windows finally arrived in early July and were installed over a three day period. There was a total of 28 windows. Some installation required extra work, but this was accomplished by the highly skilled team of Phil and Orlando. Gary was onsite during the entire procedure. I cannot overemphasize my satisfaction with the job performed. They even removed all my blinds and reinstalled them after the windows were put in. Get quotes from every company you want, but I guarantee that you will choose to hire Goodfellows Windows for your project. They are the BEST."

"Rafael was great - he fixed our front door knob and lock, replaced another door handle, and our towel bar. He worked us into his busy schedule and came by on a day that was best for me. Rafael picked up parts he needed at Home Depot after assessing what we needed, and efficiently completed all three jobs."

"Elvin is great. He fixed my wood double front doors and applied paint that I had picked out, as well as new handles/lock. He took his time, was very polite, and made sure everything was in order before in left. My front doors look amazing. Will be hiring him again for more work around the house. Also, his pricing was very reasonable and on point for the amount of repair and painting work he did."

Doors FAQs, answered by experts

The most common rough opening for a sliding glass door is 60 inches to 72 inches by 80 inches. A rough opening is the unframed space where your door will go.

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

If your specific sliding glass door model is out of stock or no longer being built, it may still be best to contact the original manufacturer or installer. They can suggest a comparable replacement that is similar in size, avoiding more expensive repairs to retrofit a new door to an older opening. 

Installing a dog door into an existing door is a quicker, easier project than installing one in a wall. Installing a pet door into a wall requires cutting through your home’s drywall, ensuring no pipes or wires are cut, and sealing the new opening so as not to compromise the safety and stability of your home’s walls, all of which may be a bigger project than many homeowners are looking to undertake.

When hanging a door frame, it’s recommended that you use screws, not nails. Screws are more secure, easier to tighten, and easier to remove if you need to adjust the frame. On average, the cost to replace a door frame is about $400, but you can save on labor costs if you’re confident in your ability to DIY the project.
