"TJ installed three exterior doors in the house I recently moved to. We were suspicious of a lot of rot under the doors, especially the large front door, and wanted to make sure new doors were not just installed, but the entire framing repaired and replaced before new doors went in. TJ measured everything before his estimate (which was highly detailed and accurate) and came back to confirm measurements before ordering materials. He completed the work in the exact timeline he had given us, and was great at communicating over text and phone calls. He found and repaired the rot under the front door, and then repaired and installed two normal sized exterior doors, including our basement door which was a mess to begin with. TJ also had to deal with some not-so-great flooring installation from the previous owners, and he made it work. The floor looks great, you could never tell there was a 3ft by 5ft section removed and repaired just a day before. With TJ's help, we were able to custom order the exact door style we wanted, and he helped us with some design and materials choices. The house has been given an incredible facelift, and I feel so much better knowing the doors are safe and sturdy. TJ was extremely courteous and thoughtful in his work. He left the work area and property looking immaculate each day he worked with us. He was also very conscientious with our dog, which I appreciated. I have received massive compliments on all the doors, and will be working with TJ again for our deck this summer. We signed the contract with confidence and excitement because TJ's results are very professional and will certainly last a lifetime."

"Bob inspected the window frames and provided a few solutions I hadn’t considered. Same for interior doors no longer hanging properly. Although I typically prefer paying by the job instead of by the hour, Bob was quite focused on his work and use of time. I will be asking him to return in the spring to complete a few additional repairs and install a storm door."

Window Door Contractors FAQs, answered by experts

Many windows carry warranties from the manufacturer or installer that may cover the cost of repairs for a fixed amount of time. When installing or replacing windows, ask about any applicable warranties, what kinds of damage and repair they may cover, and what the procedure is for making a warranty claim.

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

Most standard windows can accommodate solar screens, but specialty shapes or non-standard frames may require custom solutions. It’s important to consult with a professional to ensure compatibility and proper fit for unique window designs. Arched, bay, and fabricated windows often need fabricated screens, which can increase costs and lead time.

If you’d rather repair your screen door mesh than replace it, you can patch it. Purchase a mesh patch for screen doors with small holes or tears, especially if the mesh is pretty new. Hardware stores and websites sell mesh patches that are easy to apply with an adhesive or a warm hair dryer. Keep in mind that repairs won’t look as aesthetically pleasing in most cases as a full replacement. 

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.
