"Home Genius Exteriors is amazing! I have been impressed throughout the whole process with their high level of professionalism and depth of expertise. Every person I have met throughout my project has been a dream! I honestly believe they care as much about my home and doing what is best for me and my family as I do. I highly recommend! Long story about my incredible experience so far below: Our roof and siding were older, losing grit and fading, and we had lost some shingles in a storm. After having another company out that was okay/average, I did some research and read a ton of reviews. Home Genius Exteriors really stood out from the rest, so we decided to setup an appointment. Our Home Remodeling Expert was named John and he was the best! He did a complete and thorough inspection of our home inside and out (including using a drone). He even went up into our attic mid-summer to see what was going on under the roof. He then took us though all of the photos and videos and explained what was happening. He also listened to what we were hoping to improve. He provided multiple options and recommendations and answered all of our questions and concerns. Next thing I knew we were creating models of our actual home and toggling between different colors, styles, materials, etc. John was extremely patient as it took a while for us to get it dialed in just right. He wrote up our project, helped to find some discounts and areas we could save money to stay within our budget without compromising the end result we were now in love with. We decided to get a roof, siding, windows, patio door, and gutter replacement to completely makeover and modernize our home. The next day we were contacted by our Home Genius project coordinators Tiffany and Beth to schedule our roof install and to have a technician out to remeasure and confirm our windows/patio door order. I figured it would be a while to get on the schedule...They blew me away. Measurement appointment tomorrow and roof install the next day! Our measurement technician was named Frank and he arrived on time, took off his shoes without being asked (love that), and his attention to detail was impeccable. He even went as far as to reconfirm our order and to walk us through what to expect with the windows and patio door install. That afternoon Brandon, our Home Genius Project Manager for the roof install, called to introduce himself and provide a detailed timeline for the day of the install and to see if we had any questions. He also informed us when the dumpster and materials would arrive that evening. The next morning Brandon and the roofing installation crew showed up at 7:00 and began prepping our home, including hanging tarps from the roof to protect our landscaping and even moving all of our deck & patio furniture out into the yard for protection. Then the work really started - the crew was incredibly fast and efficient! They had all of the old roof off in less than 3hrs. By lunch they were done laying the new underlayment and starting to put on shingles. They worked non-stop. The roof was finished by 8:00 and what I really appreciate, is they spent almost an hour cleaning up the jobsite and even using magnets to make sure no nails were left behind in the grass or landscaping. Brandon was terrific throughout the project. He provided detailed explanations of what was happening, provided updates on timing and progress, answered all of our questions, and made sure that the installation was perfect. He even came by the next day to do a second final walkthrough to make sure nothing was missed since it was getting dark the night before. Roof looks amazing and we could not be happier! Can not wait for the next stages of our home transformation!"

"CJ Construction reconstructed a bridge that I need to go over a creek so I can get my riding mower to the back of my property. He was friendly, efficient, professional and did this unusual project at a good price. He was very thorough and made the bridge stronger and better than it ever was. I would hire him again for any project he was willing to do. No mess and considerate of property. I would hire Jeff again without even looking for another company."

"Hired to replace 2 window screens on the second story of our home. Val found another one that needed replacing, and he did that one too, for no additional charge. He also fixed our kitchen light so that it stopped blinking when we first turned it on. Friendly, courteous, punctual and professional. Will be hiring again."

Window Door Contractors FAQs, answered by experts

Yes, you can fix windows without replacing them. However, this will depend on the severity of the issue and what your needs are. Minor water damage, broken glass, damaged casing, and worn caulking are usually easy repairs. But if there is excessive damage, the windows are constantly foggy, or the windows are very old, it’s best to consider replacing them. Replacement windows cost between $575 and $1,475 per window, or an average of $850 per window. 

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

No, but removing window screens will achieve a deeper clean. If you aren’t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

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.
