"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."

"Needed window sill removed and new one installed. The quote was great and the work wondeful. Looks like the original window sill. Everything was left clean and tidy. Very professional. And I am waiting for a quote for another job because of this great experience. Would highly recommend Clukey Construction."

"Mr. Phalan took care of a tricky repair to an old style solid wood exterior door on a 2nd floor deck. The door was quite heavy and had several glass panels in it, too. Bob quickly rebuilt the busted hinge and had the old door working “better than new”, in about 30 minutes. Quick and clean job!"

"I waited a while because they are backed up due to Covid but they were definitely worth the wait. They were precise, quick and extremely detailed. They put two windows in for me (where windows didn't exist before) and covered up a window. They insulated and everything. No painting but that was cool. I was very impressed. Definitely would recommend them and hire them again...and again....and again"

Window Door Contractors FAQs, answered by experts

Tears, holes, or difficulty in opening and closing suggest a need for repair.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.

No, it’s not safe to leave a doggy door open. It might be more convenient, especially at night when you just want to lay in bed. However, when you leave it open, it increases the chance of other critters getting in without your knowledge. Also, it leaves your pup unsupervised for hours at a time.

Rescreening a door costs an average of $7 to $150. It’s a relatively easy process that only requires 30 minutes to an hour’s work.
