As the nation’s largest full-service exterior home remodeler, we are backed by over 1,000+ Angi Super Service awards and more than one million happy customers. Why? Because we treat each job as an audition. An opportunity to prove ourselves to you. And the results speak for themselves. So make your home all it was meant to be with our unrivaled exterior services. Contact us today for a free, no obligation estimate on replacement windows, roofing, siding, doors, or attic insulation.

"4/ 8/22: We contracted with Power Home Remodeling to have all our windows replaced, new siding installed, a new front and basement door installed and shutters installed. The job was scheduled to be done in mid-February. This was supposed to be approximately a 5 day job. As of today, April 8th, it remains uncompleted. Two windows were measured incorrectly, and the replacements could not be installed. We needed to wait for new windows to be manufactured. No big deal for us. We liked the product and were willing to wait. Then at the end of day of installation, we found several new window screens had rips in them. They needed replacement. The majority of the screens were not stretched tight enough on their frames. They were getting pulled and stretched in a light wind. In addition, The brick molding for the basement door wasn’t completed. Two back windows were not boxed out when the siding was installed. The tin work around an arched window needs to be redone because it wasn’t secured well and is loose and floppy. And our front door would not lock without us pulling up on the door knob to engage the bolt. The front door is out of plumb and needs to be completely reset, and the bottom edge of the door is cracked. Our project manager saw these problems in person. He even noticed some of them before we did. We were told all of this would be remedied, including a new door, new screens, etc. And we were ok with that. Even after finding over 50 aluminum nails in our driveway that were not cleaned up (We’re still finding them. Fortunately no flat tires) we were willing to give the company the benefit of the doubt. Mainly because our project manager was doing his best. Our work date was changed a couple times-windows not ready, bad weather. Ok. These things happen. We waited. Then we were told that today would be the day when the work would be completed. This was confirmed twice by phone calls from the home office. This morning my husband moved furniture, took curtains down, put tarps down, paid for our dog to be boarded for the day. At 7:22AM, my husband received a voicemail message from our project manager telling us he didn’t know who in the home office told us they were coming today, but they were still on another job and would not be coming for another 4 days. My husband (with a leg injury) now had to move everything back. We did our research with this company. We own a 1000 sq for home. We are by no means wealthy. But we wanted quality product. We are paying A LOT of money for this work. I waited until now to submit a review because I honestly wanted to be fair and give things a chance to get ironed out. I would have given one star, but our project manager has really tried, and the house does look nice. But nice doesn’t cut it if quality isn’t there too. The second star is for our project manager alone. We are very disappointed and questioning our decision to have this work done. Maybe in the future I can update this review to something more positive, but based on our experience to date, we cannot recommend Power Home Remodeling and regret our decision to contract them for this work. 4/11/22 Update: Today was supposed to be the day everything was corrected. I received a voice mail 2 days ago stating the crew would be here between 8-10AM today. At 11:00AM we contacted them. And they are not coming today. Nobody notified us. Not sure how long we would have waited before someone did. Once again,we moved furniture,put tarps down, paid for our dog to be boarded. I’d give no stars if I could. Never again. Poor installation, damaged material, poor cleanup, terrible customer service. This isn’t how you treat clients who are paying you 50+ grand."

FAQs for glass block window service projects in Thornwood, NY

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
