"Rick did a FABULOUS job installing a replacement window over my kitchen sink. He very carefully removed all existing trim, installed the window quickly, and reinstalled the trim. He did a great job sealing and caulking everything. He brought all the right tools, cleaned things up as he went along, and left my kitchen looking better than ever. He was early, very friendly, and I will definitely recommend him to friends/family and will hire him for my next project! Price was very reasonable. Great job!!!"

"Excellent workmanship and communications. Ours was a relatively small job for them ($700). But, in a way, I believe a small job says something important about a business that often does jobs that cost thousands of dollars. The office communications in setting up the job were very responsive. The two craftsmen that worked on the job were communicative in what they were doing, and worked in a very professional manner. After completion of the work there was a little mix-up in processing the invoice; however, that was resolved with integrity by the office and field representative working together. I would contract with Graves Brothers again; in fact have scheduled another project for them to replace two attic windows and install a large fan in one of the attic windows."

"I requested a repair for my storm door. I was contacted very quickly and the repair was done that day. I am very satisfied with the quality of work. I highly recommend."

We replaced every window in our house and it was completed in a timely fashion. We have work in the future that he will receive because we know his price will be fair and the work will be great again for us! Thanks Sabino, you are a hard worker."

"Yes Jamie was very helpful in everything I asked of her. She is strong and was able to use a shovel to dig and plant many plants. She also did a great job cleaning the kitchen and baths. Jamie is very easy to talk to and she follows directions well. I look forward to working with her again."
