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 and door contracting 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.

The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.

Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.

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.

It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
