We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years.

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.

"Everything from picking out the windows and door, to scheduling, to installation—it was so easy and flawless! The crew who did the installation were incredible! They showed up on time, were extremely friendly and professional, and worked very efficiently. They kept the house super clean while they worked, and cleaned up thoroughly when done. The windows themselves are high quality. We can already tell that sound and air is not coming in around them like before."

"We've had Mark and his crew replace all of our windows over the past two years. We were so pleased with the first group that we had them replace the rest this year. I researched windows made in the USA and these are even better yet - made in PA. The windows are far superior than others we looked at. They did a fantastic job from the estimate, to the measurements to the install. Everyone was very friendly and courteous. But most of all they were extremely clean and conscientious about tracking dirt onto our new flooring and carpets. They laid drop clothes in every room and took shoes off to do it.

Install America
We are a full-service installation company in the home improvement industry, and have been for over 65 years! The services we specialize in replacing: Roofing, Siding, Decks, Patios, Windows, Doors, Bathtubs/Showers, Cabinets and more. We even provide a free no-obligation estimate that will be good for 12 months, so that you have all of the information you need to know about your project.
"I'd like to share my disappointment and frustration with the recent bathroom remodeling project that Install America completed for me. The project was signed on October 29, 2022, started on January 12, 2023 and was supposed to be completed within 1-2 weeks. However, the project did not finish until March 27, 2023, taking over 2.5 months instead of the promised timeline. This significant delay caused me a great deal of inconvenience as it disrupted all my life plans. Additionally, living on the construction site for 2.5 months was unhealthy and stressful, which exhausted my nerves. Furthermore, I was disappointed with the lack of from the assigned project manager. The project manager never called back to provide updates on the project's progress, which left me in the dark about the timeline for completion. To make matters worse, after agreeing on the cost of the project, the salesperson added an additional $10K, referring to the fact that something was forgotten. This is unprofessional and unfair. Quality and quantity of work performed does not match the cost of the project, and I feel that I am being overcharged for services that were not adequately provided and while I have attempted to address my concerns with management, I have been met with resistance and have not received an itemized bill that justifies the charges. In response to these inconveniences, Install America graciously installed two additional niches (that were already in the contract), which is not adequate compensation for the stress and inconvenience caused. The $500 compensation was also insufficient. Overall, I am extremely dissatisfied with the service provided by Install America. I do not recommend Install America to anyone. Stay away from them.

FAQs for glass block window service projects in Johnstown, PA
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
