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

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

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.

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.

Glass blocks provide privacy, natural light diffusion, insulation, and a decorative aesthetic.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.
