"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 the wonderful experience of having Capital Construction reside our home with Hardie Board in March. The old wood siding had not been kept up and we knew we would need to address it soon, however, we were intimidated by the scale and unknown of the project. The Capital Construction team was informative, not pushy and shared the same passion for our vision for our home. Our project manager, Jay, was personable, communicative with us, and was transparent about possible things that could emerge with the lack of upkeep, so we felt informed in making decisions throughout the process. Eddie and his crew were beyond friendly and impressed us daily with their work ethic. I left for work the morning they started and returned to have find them already having removed all of the old siding in one day. We were informed the project could take 2-3 weeks and they managed to complete it in 6 work days, which blew us away. Eddie also worked with us in developing a custom hay door as part of our vision. We continue to see people slow down and look at the home even months later and we often get compliments from our neighbors. The best feedback came from our next door neighbor who grew up in the home when he walked over and mentioned "I never imagined it could be so beautiful". The pictures speak for themselves. Thank you Capital Construction for helping make the home of our dreams."

"I hired Cody for so many projects! He painted my roof, the outside of my house, detailed work inside. He re-glazed my windows, sanded and painted my ceilings, repainted my radiators, and more. His work is perfect and detailed oriented. He also staged my house painting over the course of the summer in order to make it easy for me to pay for it. Cody is also extremely polite and pleasant to be around. I highly recommend him."

Window Door Contractors FAQs, answered by experts

Solar screens are low-maintenance but benefit from occasional cleaning with mild soap and water. Avoid using harsh chemicals or pressure washing, as these can damage the mesh. Inspect screens annually for tears or loose frames to maintain performance. In dusty or coastal areas, more frequent cleaning may be necessary to prevent buildup.

Window screens can take anywhere between 10 minutes and an hour to replace, depending on the complexity of the replacement and the accessibility of the window. Replacing the screen inside an existing frame normally takes longer than replacing an entire screen, frame and all, if you purchase a prefabricated screen already mounted on the frame.

The steps to replace a retractable screen can vary, but these are the general steps: First, remove the screen cover to expose the screen mechanism and remove the clip that holds the screen in place. Next, depress the end of the screen mechanism so it releases from the door frame. Take your new screen and fit one end into the frame. You may need to rotate the mechanism to engage the spring before inserting the other end into the frame. Finally, pull the screen down the length of the door’s opening and lock it in place with the clip.

Among the various entry points into your residence, it's crucial to recognize that your basement windows are arguably the most susceptible. Basements usually have windows facing the side and back yards, often concealed from driveway floodlights, porch lighting, and doorbell cameras. Their vulnerability underscores the importance of reinforcing basement window security to safeguard your home from break-ins.

Yes, if you have ventilated skylights, you can install insect screens on them. Insect screens for skylights cost $10 to $50 each, depending on their size and quality. Most pros highly recommend insect screens for ventilated skylights because they keep pests outside of your home while allowing fresh air inside.
