"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."

"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."

NOVA Exteriors, Inc. is a 12 time Angie's List Super Service Award Winner in several categories. We specialize in exterior remodeling and have over 50 years combined experience in the Metropolitan Area. We take pride in our work and we would appreciate the opportunity to showcase our services.

"NOVA Exteriors did a wonderful job replacing 3 exterior doors at our home. They checked every box one could ask for. Rob our sales rep was patient and understanding of our needs - even coming back a second time as we had a hard time deciding on what we wanted. Their team worked quickly and did a great job installing some beautiful new doors. We noticed after the installation that there were some imperfections on the hardware installed and they have agreed to replace them & their customer service was top notch. They responded quickly to some minor concerns and went above and beyond to fix the problem. While doors are never cheap, their price was right in line with other Provia vendors and 1/2 the price of Pella vendors. I'd highly recommend them."

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
