Get matched with top security door installation pros in Annandale, VA

"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"There’s nothing like having the best of the best. I’ve used the other big security names before like Vivint and Brinks. They are OK. But after getting acclimated with ADT, it is clear why they are the best. Pricing is fair, equipment is reliable, and every one genuinely seems happy at their job. This goes a long way to a paying customer. Just our perspective for anyone else that is considering all of the big providers in the alarm system landscape. ADT is well well worth it."

"Went very well. Installed quickly and efficently from the smoke/carbon deyectors to assisting with the nest app. Very professional."

"They are very responsive, timely and fixed my problems. They work with us on an annual basis."

"Excellent and professional service. I would highly recommend Absolute Electric."

"The Century Siding team wrapped our wood rakeboards (three storeys above ground on both sides of the house) in aluminum. They did an absolutely fantastic job - very efficient, timely, and courteous. The quality of the work was excellent and they took the time to discuss what they did in some detail, so full marks for their communication. Overall, this is a firm whom we will be returning to for other work. They were recommended to us by a trusted contractor."

"Our builder grade 1990s wood windows, door, transom and site-lite windows had all suffered from age and neglected painting. They were all long overdue for replacement and then we discovered Zen Windows of Washington, DC. They are consummate professionals. Their high quality, energy efficient products backed by a transferable lifetime warranty, strong technical knowledge, excellent value (price/quality relationship), pressure free consultative sales approach, and absolutely incredible install team left us 100% satisfied from beginning to end. The leader of the install team promised us that they would do the install as if it was his own home and actually did! I am very detail oriented and given the complexity of the job, their work was truly unbelievable. It’s perfect! Don’t waste your time with Andersen, Pella, Thompson Creek or others. Look no further than Zen Windows of Washington DC and work together with them to find the best solution for you. You will be very happy you did."

"We were looking to increase our attic insulation and met The Home Doctor Company at the Capital Remodel and Garden Show in February 2025 as well as some other companies. We consulted with several companies and decided to go with The Hone Doctor for our attic insulation. The company rep, Chris Lear, was very good explaining what they would do and why our attic needed R-38 insulation. I knew we needed more but did not realize our attic was only R-13. I have worked with numerous contractors before on projects and felt this was a really good company plus they have great reviews. The installation of the attic insulation went very well. They do install siding as well but decided to put this project off for now. Would highly recommend this company."

"They were great—came out same day, reasonable price, and they were very nice and easy to work with. Will def use again for any electrical needs."

"We hired Unicorp to replace all our windows, doors, and siding—and the result has been an amazing transformation of the entire house. Not only was the work done to perfection, but the people we dealt with at every stage made the whole experience a pleasure. From the start, our sales rep Alex was informative and responsive, answering all our questions over several weeks—so that by the time we signed the contract, we were totally comfortable with the project design, and knew what to expect when work began. Paul was in charge of the window and door installation. He and his crew finished all the work in just two days, and kept the work areas clean as well. Everyone was friendly and courteous, and Paul himself was an unforgettable character. Window replacement can be an overwhelming job, since it involves every room in the house, but Paul made it fun with entertaining conversation. And he was an artist with the trim capping, making sure to match the style of our colonial house so that the windows would have definition instead of appearing flat. The windows and doors themselves are top-of-the-line quality. They instantly modernized the house, and because of the improved energy efficiency, our AC is able to maintain the house temperature so much better in the blazing hot summer. JR was in charge of the siding job and other finishing touches. His crew, Nam and Augustine, were incredibly talented and hardworking (even after driving four hours to our house each morning)! They completed the siding on our addition in just one day. The end result is stunning, and the insulated vinyl siding has made the addition much quieter and more comfortable. JR came up with creative solutions, like figuring out how to design the columns and header so that they’d fit in the tight spaces around our door. And he was always easy to reach by phone or text. There were a few issues with the materials delivered for the shutters and the door surround, which caused some delays toward the very end of the project. But JR was committed to making everything perfect, and he came back himself to do the final installation and painting. This was the largest renovation project we’ve ever undertaken, and Unicorp made it such a positive experience. We couldn’t be happier with our “new” house, and we look forward to calling them again, when it’s time for us to get a new roof!"
