Great in all ways. Friendly and helpful workers did an amazing job, with our white siding looking fresh and bright again and windows sparkling. Deck and concrete and gutter cleaning top rate. I recommend this company to everyone- accommodating service and beautiful outcome. Top rating!

Excellent! I asked if they could respond in a very tight window of time, between when one set of vacation renters were leaving, and when new renters were coming in that same day. They were able to get my work done in my requested window of time! Amazing service!

Couldn't have gone better. Santiago was the first to reply to my email and he came the next day to give us an estimate. I never even saw anyone else; I hired him on the spot. He started on the day he said he would and it was a wonderful exprerience to work with someone as lovely as Santiago...

They needed to be paid for half the product before the windows were either done, which was kind of a hassle, but other than that it had been pretty good. Other than that there have not been any issues.

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."

FAQs for glass block window service projects in Geneva, 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
