"Devon is, simply put, an incredible contractor. Having dealt with many others in the past, I was pleasantly surprised by Devon's unwavering efforts to keep me apprised of every step of the siding/trim job. He went above and beyond my expectations, even taking the time to update me with pictures and videos to show the project's progress. Devon is a rare gem in this industry; he is extremely responsive, diligent, timely and talented — and not to mention, a very kind and friendly person. Any questions I had were answered right away and he always made sure to run next steps by me before proceeding. I cannot recommend DMM enough. He will blow you away with the beautiful quality of his work, attention to detail, and the dedication he puts into his craft. It's not just another gig to him — he truly cares about making your vision come to life. One of the best decisions I made for my new house. Thank you DMM!"

"We had a top to bottom, excellent experience with the local team from Universal. My wife and I had an in-home consultation, a measurement and the install completed in a little over a months time. As stated in a prior review, the cost is reflected in the quality of the workmanship. Our family could not be happier with our experience. Big thanks to Kyle, Ron, Mike and Dennis for the top-notch service. I can wholeheartedly recommend Universal Windows Direct to any homeowner in need of a new door, installed quickly and by a friendly, knowledgeable and friendly staff. Thank you again!"

"Dustin C. @ DaBella Boise helped us choose the right windows for our application and personally monitored progress from order to completion. The finished product looks great, but the best part is instantly seeing and feeling the difference between modern tech vs. 40y old aluminum framed windows. No more drafts or condensation! Thanks DaBella!"

"They did an excellent job. Put a threshold drain in front of a sliding door to my patio. They had to remove pavers, install a 4 inch pipe across the lawn and replace the pavers and sod. Hard workers did a really good job."

Window Door Contractors FAQs, answered by experts

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.

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.

While the benefits of garage door screens usually outweigh the downsides, there are some cons to installing one. First off, they can be quite expensive, especially if you’re having a professional install a retracting screen or a custom size screen. Second, they let fresh air and natural light in, but they also don’t provide the same privacy from people in the neighborhood that a solid door does. As you might guess, screens also won’t insulate your garage, so they’re often not usable in colder weather.

It’s possible to make minor screen repairs yourself using a waterproof adhesive for small tears or a screen patch kit for larger tears and holes. However, it’s usually a better option to call in a professional window technician. It’s very easy to use too much waterproof glue, resulting in a messy appearance that might demand a full replacement anyway. A screen repair technician will not only be able to carry out clean repairs and patches that aren’t obvious, but they can also let you know if replacing your screen is a more cost-effective option.

While the telltale signs can vary for different types of screen doors, it may be time to learn how to install a screen door if you're noticing rotting, warping, or splintering accompanying the sagging. If you’re unsure whether to replace a sagging screen door, consult a local screen door pro for an inspection and final decision.
