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 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 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.
Window replacement can become costly, especially if you’re replacing your whole home. There are a few steps you can take to help save money on the bottom cost while still giving your windows a facelift.
Replace multiple windows at once to bundle your purchase
Inquire about discounts, coupons, or special offers
Consider window repair as soon as you see damage to help prevent the need for replacement
Maintain your windows often by inspecting your windows for drafts, leaks, and cracks
There are certain window repairs that are cost-effective to DIY and relatively simple for homeowners to tackle themselves. Tasks like replacing a screen, replacing a lock, or sealing a window are typically under $30 and take minimal time to do yourself. However, if you need to replace your window or repair a broken double pane, it’s best to call in a professional window replacement installer to lend a hand. Replacing the majority or all of the windows in your home is a time consuming job and best left to a professional.
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.
The time it takes to replace a window is a total of four to 15 weeks. This time includes your initial consultation, appointments for measuring, as well as ordering and manufacturing your windows. For a smaller job, you can expect the total timeline to be on the shorter end, but for a whole house window replacement, it might take longer (or be split into multiple install appointments). Once your windows are created and ready to be installed, your window installer will take 30 to 60 minutes per window to install.
