"Brian replaced 2 of my windows that had broken seals. He replaced the missing shower doors that the previous owner had removed. I had already purchased the doors at Home Depot but the person helping me gave me the wrong size. Brian loaded up the wrong doors and went with me to get ones that would fit. Technically, they should have been specialty doors because my shower isnâ t square like it should be. Youâ d never know it because Brianâ s work is impeccable. Brian is honest and conscientious. He goes above and beyond and is reasonably priced. He cleaned up after himself, which many contractors donâ t do. He does great work. If youâ re looking for someone that will do his very best for you then chose Brian with Beckwith Glass. I wish that I could give him more than5â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸ â­ ï¸"

"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!"

"The project went great; I'm very happy with the final product. It lines up exactly with what I was looking for at the start of the project and looks better than I could have planned because of some great design suggestions from Wagner Home Renovation along the way. We ended up creating two separate closets from the previous closet incorporating some previously unused space in the condo as well. Both closets are accessed through very nice double doors. The laundry closet and general/clothes closet both look great. Wagner Home Renovation used high quality repurposed wood from a previous project and black iron rods to give the general/clothes closet great character. All of the work was very well done, and blends into the existing paint and trim-work so well, you can't even tell any work has been done. As an example, they added a wooden keystone at the enlarged entranceway near the new closets that was a very nice touch and feels like it was always there. They were able to save me money throughout the project by offering to use repurposed wood from previous projects that was often better quality than what would normally be used. Wagner Home Renovation does high-quality work and has a genuine interest in how well the end result turns out. They have a great attention for detail, offer great design ideas and options, and are responsive, honest, budget-conscious, flexible, reliable and easy to work with. I highly recommend them."

"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!"

Window Door Contractors FAQs, answered by experts

The most affordable way to screen in a porch is to add a base track system to an existing wooden frame. The whole process should cost around $2,000 for supplies, depending on the size of your porch. It’s much pricier to build a screened-in porch or sunroom from scratch—and you’ll probably need to hire a contractor for a project like that.

Yes, a variety of screen materials cut out glare from the sun. Solar screen material can block up to 90% of the glare and heat from the sun, saving on cooling costs. It also offers privacy yet unlimited outward visibility. The cost depends on the size of the screen roll, but solar screens cost between $25 and $90 per roll.

You can trim an overhead garage door screen to fit your garage door opening. This is a particularly helpful hack if you have an irregularly sized garage door opening but are still interested in installing a garage door screen to keep pests and debris out. Trim the garage door screen carefully to avoid unsightly edges or an uneven fit.

The screen material you choose depends on your needs. Here are some differences to consider:

  • Fiberglass is the least expensive but needs replacing more often.

  • Aluminum suits almost any job and doesn’t stretch as easily as fiberglass. 

  • Pet-resistant screens are more expensive than fiberglass or aluminum, but they’re also wind and weather-resistant. 

  • Metal screens, like stainless steel, are the most expensive material for rescreening your porch or sunroom. However, they last for years and are golf ball-resistant.  

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.
