Simply put - we believe that improving your home should be enjoyable. That is why we spent years designing our consultations, installations, and customer care experiences to minimize stress and provide every client with a fair and honest home improvement experience. Founded in 2005, Windows on Washington has become one of the area’s most respected home improvement companies because we make our clients' homes more beautiful, comfortable, and energy efficient. We are proud Angie’s Super Service Award winners, which we’ve now earned for seven consecutive years. We have an A+ rating with the Better Business Bureau and have never had one filed complaint. In addition, we have hundreds of positive customer reviews on Angie’s List, Customer Lobby, Home Advisor, Guild Quality, Houzz, and Yelp.

"So this is going to be my first review online and I’ve decided to provide it because of both the size of the projects involved and the quality of service that I received. My family and I recently purchased a 45-year old fixer-upper in Northern Virginia, and the home needed major updates throughout. Two things that needed immediate attention were the original wood windows and the 30+ year old asphalt roof. After a referral from a co-worker, I reached out to Windows on Washington and spoke with Greg for help on the windows. He was very knowledgeable and answered all of our questions, without any pressure to commit on the spot. The windows they use are very well-reviewed (Okna) and offered all of the features we were looking for. His quote for the 40+ windows and one new door was incredibly reasonable and less than other quotes I received. Based on the stellar feedback I’d already received about the company, I agreed to enlist them for the project. Their crew arrived on-time and spent two days doing an exceptional job installing everything. I watched them do the installations and everything was top notch. The windows dramatically improved the look and energy efficiency of the house, and the entire team could not have been more professional. I would HIGHLY recommend this company to anyone if you need replacement windows. During the discussion with Greg about windows, I mentioned the need for a new roof, specifically a new metal roof. He indicated that their company could also handle that project since the president of the company (Eric Novotny) was very knowledgeable about those. I spoke with Eric a couple of days later and discovered that he is part of an expert industry panel for the Metal Roofing Alliance. We went over all the options for installing a metal roof and he came out to our house to talk at length about what we could do. He provided a quote for the project a couple of days later which was very reasonable based on the research I had done and I signed up for that as well. Interestingly, the roof project was completed first (before the windows) and his team spent three days completing everything. The crews worked 12+ hour days to get things done and the work was all top notch. It was beautiful when it was finished and our family couldn’t be happier. As a follow up, two weeks after the roof was completed, I had a chimney cleaning / repair company come out to do some minor work. They ended up severely scratching all of the panels around the chimney in the process and I needed Eric’s team to fix it. He sent two guys out and they spent 12+ hours carefully removing what they had just installed and replacing everything exactly the way it was. I expected the cost for the repair to be significant, but I was very surprised that not only was the cost reasonable, but some of the same crew that did the initial installation were available to come out and do the repairs. It was a very confidence-inspiring extra step and further reassures me that we went with the right company. Overall, I can’t endorse this company and the people I interacted with enough. I didn’t have a single bad experience and I feel like the money we spent was an investment we will enjoy for decades to come. I also know that if something comes up down the road, Eric and his team will be there to help us out. Bill S."

At The Home Doctor, we go beyond exterior improvements – we protect the health of your home. As a locally owned and operated business, our mission is simple: to provide you, our valued homeowner, with superior products and personalized service. Big Savings: Limited Time Only – 50% OFF Installation TERMS AND CONDITIONS: Offer valid on complete replacement projects of 10+ windows, entire roofs, or all sides of siding. Gutter, door, and attic insulation projects qualify with a minimum job cost of $7,500. Discount applies to 50% off installation costs only, which typically account for 20-30% of the total job cost, resulting in a 10-15% overall project discount. Valid for new contracts only, cannot be combined with other offers. Valid on initial visit only, and has no cash value. Residential projects only; exclusions apply. Deferred payments only valid with this promotion. The Home Doctor reserves the right to modify or cancel this promotion at any time.

"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."

"Our review is based on the purchase (part 1) for replacing siding for both side of our home. Jacob L. was very professional, on time, and honest. He knows what he is selling. We learned a lot about our home during his presentation. Before we bought our home we paid for a professional home inspection. We thought our house inspector was very good but he did miss something---the siding on the sides of our home was installed extremely bad. Jacob pointed out so much that we just didn't know and should have be caught during our home inpection. Thanks Jacob!!"

"Had windows and doors installed by this company. The window installation went great. The bad news is that they do not seem competent at installing door hardware. My door has not latched properly since they made some unwanted modifications to the hardware (it worked perfectly before they started modifying it).have had them out three separate times to fix the issue they caused with the door latch and lock. Every “fix” they do seems to make the problem worse. I would steer clear of this company for door installations."

"We hired Unicorp to change front door because of superb review on Angi, but disappointed. 1. It's a small company using subcontractors to do its work; Contrary to its claim, those subcontractors DO NOT work exclusively for Unicorp. 2. After subcontractors got paid, you will not see them again for the job. The service team seems only one person (JR). It is hard to make an appt, since he has to supervise a lot of subcontractors' work, and only do service when he is supervising near you. Specific problems: -Ghost swing after installation (i.e. door swings to close by itself). Had to request adjustment at least twice. -Fainted finish after a few years while still in warranty, but we were advised to paint ourselves. -Very thin layer of finish, and very easy to get scratch to show white underline color; -Have PROBLEM to LOCK the door. After it was "fixed", problem showed again. -Subcontractor used wood with black stains, suspect mold, to install the door; Brand new door had minor defect."

Glass block window services FAQs

If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

The average cost to install glass block windows is about $710, ranging from $460 to $1,000, depending on the size and design of the window, installation type, and location. Different styles of glass blocks also impact the cost:

  • Clear glass blocks: $10–$30 per block

  • Colored glass blocks: $25–$40 per block

  • Acrylic glass blocks: $15–$25 per block

  • Wavy glass blocks: $10–$30 per block

  • Alpha glass blocks: $15–$25 per block

  • Ice glass blocks: $20–$35 per block

  • Diamond glass blocks: $20–$75 per block

  • Frosted glass blocks: $30–$35 per block
