Joe of MJ Squeaky Clean did an amazing job. He was prompt, very professional, hard-working and a complete pleasure to work with. He did both the outside and inside for a very reasonable price and the windows are sparkling clean.
- Kathy C.
Installer was very pleasant and neat in the work he was doing. Put the window in and cleaned up the mess. Took about 11/2 hours.
- Darryl J.
Things went well before it was time to build. Then there was a problem with who Ed Miller sub-contracted the work to build the foundation (Wayne Block). To be fair, there were unforeseen problems with my soil, which in turn, changed how the foundation would be built. The problem started when...
- Eric S.
I am very impressed! Initially, a kid walking through the neighborhood with a clipboard caught me doing yard work and asked about my windows. I had been meaning to replace all my remaining ones anyway, so gave the go ahead for him to mark me for a call. Soon, I had a rep at my house...
- Jean H.
Replaced three windows in the front of our home. From the beginning Window World employees were more than professional. They gave us an estimated date the windows would be in and installed them within a weeks time. Gave us a time frame. They were punctual and courteous and left...

My old window cleaner didn't return my calls. LIke Angie said "It's hard to find service providers." I'll take that one up on the old window cleaners Angies list entries, but back to Rick. Smooth, no hassle, down to business work. I found we had some interesting things to talk aboutand...
- Anthony C.
I have been using his services from 2006 and he is the best. He doesn?t believe in replacing the window. He just removes it and restores the same and the window looks absolutely fine. He does a specialized work and the work is astonishing. He does an excellent job and slowly, with care. ...
- Peter G.
Overall, the work turned out good. I had one window installed. The installers were on time. They were pretty efficient. They really did a good job. They cleaned up well. I would use them again in the future.

Graves Brothers Home Improvement
Graves Brothers Home Improvement
Graves Brothers Home Improvement has been locally-owned and operated in Upstate N.Y. since 1977. As one of the fastest growing businesses in the region, they offer their residential and commercial clients Roofing, Siding, Windows, and other Home Improvement services. Graves is a nationally-recognized contractor that has been repeatedly named a Top 100 company in the region as well as one of the top 500 home improvement companies in the United States, annual Angie’s List certification holder, countless product certifications, and more. Graves Brothers services Upstate and Western New York and the Finger Lakes Region from their facilities in Rochester, Buffalo, and Syracuse.
"The positive: Graves Brothers will provide a quote for PARTIAL Siding projects where most companies won't talk to you unless you need a FULL Siding project. The installation team was quick and did a nice job. The Cons: Deceptive Sales. Your Typical Residential Home Services contactor. I had a complete east side siding replacement quoted. There is a 24" "Jog wall" between the exterior garage wall and the living quarters wall. Their quote included photos that show this wall in one of the views. A second photo shows the entire length of the wall outlined that includes this jog wall, but they did not replace the siding on this wall. A conversation BEFORE the project work started questioned if I intended on having the wall replaced and it was agreed that it should have been part of the proposal. The installers DID NOT replace the siding on this wall. I asked for a simple $500 credit and was willing to settle for a $350 credit which was more than fair. The Salesman insisted that seeing the wall was not assigned a "wall number" therefore it was not included in their proposal. Graves Brothers displayed ZERO interest in coming to a mutual agreement on the discrepancy. Update 7/19/2024: After continued conversations, the Sales Rep finally conceded that after speaking with his installers, that the work WAS included in the initial estimate and should have been completed. I gave Graves Brothers the option of discounting the price or returning to finish the work. They chose to finish the work which is scheduled this week. IMO, Speaking to his installation team should have been done PRIOR to him taking a flat stance with me that they were right and I was wrong. Give Graves Brothers Home Improvements a 3-Star rating for (finally) doing what was right. The installation was done well and the installers were professional, courteous and cleaned up well. Just make sure you document all conversations and get them in writing up front."

Highfield Joinery
Highfield Joinery
Highfield Joinery is a one man operation focusing in high-level historical knowledge and legacy materials, including linseed paint and putty, lime mortar, and high levels of salvage, dutchman repairs, patching, and "re-livening" wood considered unsalvageable. This can save thousands, especially for old doors and window sashes, attics, siding, and porches, while preserving the architectural integrity and therefore curb value others may not be aware of. Because of the age and uniqueness of each task, I use many hand tools which allow the flexibility and detail required, but also encourage the same results and even tool marks as the originals, and can be an absolute value over time as they may last just as long. I has become common to spend a year’s salary on a repair, only to find it failing or aged in just a short while. Our ethos is the opposite: to fix it so properly and accurately that it never needs to be looked at again in your lifetime. As the Originals Were.
"I have hired Eric for multiple furniture repairs/restorations(chairs, server/sideboard, dining table) and he has done an amazing job every time. Iâ ve been hesitant because a lot of antique furniture is just irreplaceable but everything he touches turns out beautiful. If you need someone to repair or restore your furniture, Eric is a 10/10 recommendation!"

FAQs for glass block window service projects in Williamsville, 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
