At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"The salesman was late. The person taking measurements missed a window rushing before his vacation. Which in turn delayed our project 2 weeks. The installers damaged our new porch and installed 5 defective windows. We have had 0 updates on how our windows and home will he repaired but we have received numerous. Text, emails, and posted mail begging for 5 stars including a gift card as a thanks. It has now been over 5 months and we still have windows that need to be replaced and Window Nation has fraudulently told the finance department the job is complete so we now need to pay for a job that is not completed. Avoid this company if possible."

Welcome to Apex Waterproofing, your one stop shop for whole home remodeling, residential and commercial basement waterproofing and foundation structural concerns. We are a fully licensed, bonded, and insured 3rd Generation General Contractor providing quality services to the Northern Virginia and Maryland areas since 1943.

"I used Apex to fix a situation where water would leak into my basement through the electrical panel during a long, heavy downpour. It was a particularly unique and difficult problem to solve which involved excavating under part of a flagstone patio, determining the source(s) of the leak and sealing. Their final solution was very thorough and attacked the problem from multiple directions. I was impressed with their dedication to doing the job right. The clean-up was also thorough (the patio looked better after they left than before they started!) The crew was great! They worked hard and knew what they were doing. Since it was such a tricky problem, Lou, the manager, was on-site for most of the day. They also have an excellent electrician on the team which was a definite plus for this project. I used Apex a couple of years ago to renovate the basement and was very pleased with the result of that project as well. They’ve been in the business for many years and are deservedly proud of their reputation for quality work. I wouldn’t hesitate to use them again."

"I hired Renaissance to re-tuckpoint my home in 2016. After only a few years, the mortar is failing miserably. in some places the mortar is 90% gone and the bricks are eroding. The work falls under a 10-yr warranty, but after I contacted them and David Hutton came to take a look, he has been very cagey with details and info on how the repair will proceed. He has ignored my repeated requests for details on how they will test the remaining mortar for compromise and when I requested a drawing showing the boundaries of the mortar that needs repair, he has only told me that they'll provide before and after pics. I have no faith whatsoever that this job will be properly repaired after all of this. Save yourself many headaches and lots of money and don't hire this company."

Glass Block questions, answered by experts

Installation costs range from $400 to $1,500, depending on wall size, design complexity, and labor.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

Glass blocks are much thicker than glass panes in traditional windows and serve as better insulators. The overall glass block window is sealed against drafts that allow warm or cool air to escape, saving on energy costs. Since this type of window is sealed airtight into your home, you don’t have to worry about air leaks and drafts as often as traditional windows that open and close. When installing glass block windows, look for options that are Energy Star rated, proving their energy efficiency.
