Ben was able to rebuild the windows that were rotting, fix the balances on 10+ windows and make sure every window in the house opens and closes properly. We are preparing to sell our home and I didn't know how I was going to fix my window problem, but he made it so easy. I was then able to get all the windows sanded, caulked and painted and now my stress about selling my home has been been greatly reduced. I highly recommend this business.

Our initial experience, a full home window replacement, was excellence from product quality, installation, value and customer service. Once again, this has been our experience. A call to their Chantilly office, Sheryl had Joe scheduled for a consult the next day. Our vision: a sliding glass door to replace a pair of windows, allowing backyard access. Elimination of the adjacent window paned entry door and egress, enlarging our family room living space. From our vision, Joe proposed an alternative, balancing remaining windows and transom with a custom size ProVia sliding glass door. His revisions made significant enhancement to the room's footprint and allowed us to move forward with replacement our front entry door. Here again, with my general vision, Joe brought his professional guidance and we had selections made in minutes. Our new ProVia entry door... I've never made a change to our home that has had as many compliments or requests for referral. From here, we need to thank Sheryl for her patience and professionalism accommodating scheduling adjustments, of which there were several. Ricky and his assistant managed a one day installation of both doors accommodating preparations for an exterior siding replacement and finishing with flawless interior appointments. As observant DIYers... witnessing Ricky's install was a master class in carpentry. Attention to detail was above and beyond. Lastly... my delay in posting this review has tested our ProVia doors with Virginia's '26 formidable deep freeze. They performed beautifully. We're very very satisfied customers. We wish Tom the best as he enjoys retirement and thank him for the service he extended to us to unquestionably be repeat customers. Entrusting the business with Joe and NOVA's team continues your exceptional business and solid reputation.

With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are.

The biggest issue was the rot at our dormers, leading to insects getting inside. Our gutters were also not draining rain well and needed to explore larger/better gutters as the rain in some parts came down hard close to our foundation. This was a costly project that we knew would have to take priority. I messaged Dream through Yelp, and though I was hesitant since there weren't many reviews here, I took a chance since Google showed quite a few excellent reviews. To my surprise, someone responded and called me immediately and was able to send someone out the same day for an estimate. Sean, who worked with us on our estimate, was on-time, friendly, and low pressure. He provided an estimate to repair all of the original wood trim and recommended to encase it in aluminum. The contract was very well outlined and we felt it was a fair price. The most important part for me was that it did not feel like there were any games to play, as I was expecting/fearful of this from researching window related jobs. The work team first dropped off supplies -- everything was organized so cleanly on our driveway. The next day, they showed up before 7:30am and continued to do so the rest of the week. I have never seen a team to dedicated and punctual. They showed up early DAILY and left late DAILY, were polite, and even came on the weekend to wrap things up and clean up. Everything was done with great detail and they even helped us put up our new house number plate without hesitation. I could tell from that they care about their clients and their happiness. The gutter team finished their work within a few hours... so under a day of work! Also, Sean showed up personally a couple of times to talk through our contract and estimate when we needed clarification; we appreciated the efforts he made, without any second thoughts, to visit and explain everything face to face. Because of their proven, trustworthy work, consistent follow up, and honest pricing, we will definitely use them for windows as well. They never let us down and delivered everything on time which is rare for large projects. We really look forward to working with them for all future exterior needs -- they've won us as customers for life!
