"6 month wait due to supply issues, and had to call back after install due to sloppy caulking. They did come resolve the issue promptly, and quality of the door installed is excellent."

Our number one priority is to serve our customers by anticipating their needs and exceeding their expectations. We do what it takes, every day, to make Hanson's Window and Construction, Inc., the best place for our family to serve yours.

"Install seemed to go OK, crew was great - only reason I?m giving two stars. Communication with this company was horrendous. Scheduling my initial measurements was hilarious, because their staff doesn?t understand that I work on call and my schedule can change - I would give them at least 24 hours notice in the event I needed to reschedule (which is 26 hours more notice than they gave me). The grumpy old lady that handles the scheduling gave me attitude over it - the idea that I could POSSIBLY need to reschedule - like it was the biggest inconvenience of her day, and almost lost my business right then. Stupidly, I brushed off her attitude and incompetence, and decided to proceed since I had a signed contract anyway. They were supposed to show up between 8am-12pm - waited till 10am (after I took the day off work and lost several hundred dollars) to tell me the crew couldn?t make it, and rescheduled me TWO WEEKS OUT. At this point, we?re heading into frigid temps and snow, and my broke"

Glass Block Windows questions, answered by experts

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.

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Glass block windows cost about $710 to install, ranging from $460 to $980. The cost factors of installing this type of specialty window include the opening size, design, layout, height, glass block type, installation type, and location. There are many block styles to choose from, including colored, clear, wavy, diamond, and frosted.

Consider the following price ranges of installing glass blocks based on size:

  • 25-by-25 inches: $60–$300

  • 31-by-31 inches: $65–$350

  • 36-by-36 inches: $85–$475

  • 48-by-48 inches: $155–$840

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.
