★ 5★ 4★ 3★ 2★ 1Everyone we worked with was absolutely phenomenal, I’m so grateful we went with George J Keller & Sons! Truly every staff member we worked with helped answer our questions and the crew who helped with our siding was professional, honest, transparent, friendly and knowledgeable. Big shout out to Chris who was extremely helpful during our initial consultations, and Justin and Mike who helped oversee our siding renovation from day one until completion. We got multiple estimates for this job, but I’m beyond happy we chose George J Keller and Sons because they truly made one of our biggest homeowner projects seamless and they executed without any hiccups or issues. Very grateful for everyone on the team and thanks to the workers who worked tirelessly to get our job done. We’re beyond thrilled and would highly recommend. Look forward to working with you all again in the future when we need a new roof :)
February 14 · Kelly CramerWe initially reached out to George Keller and Sons in late August 2024 for basically a whole exterior remodel (windows, siding, roof, etc.). We ended up having to press pause on the windows/siding aspect of the quote and ultimately used them to replace our roof and gutters.On roofing day, the crew showed up on time. Lenny (one of the site managers) and I did a quick walk-around of the exterior of the house and he was clear in explaining how the day was going to go. Our house was built in 1996 and to our knowledge, the roof was original. Rather than just slap a new layer of shingles on the roof and be on their way, they explained the best practice was to strip everything down completely so they could evaluate the condition of the sheathing underneath, replace any bad plywood and lay down new ice shield and underlayment. They cut in a ridge vent and added new bathroom vents to help prevent future moisture buildup in our attic. The crew protected everything at ground level and worked quickly and efficiently. My husband was working in the area that day so he popped by to check the progress and one of the guys on the crew took a few minutes to speak with him about the condition of the old roof, placement of the new vents, etc..The gutter crew came in a few days later. We increased the gutter size to 6 inches and added leaf guards. They did a great job with removing the old gutters as well. We asked that they be saved as we had another project to use them for and had plenty of salvageable material to work with.They were accommodating with our schedule from the initial consult appointment with Brendan Tully to scheduling the roof and gutters. Cory & Jen were great, working with us on scheduling and letting us know what to expect on roof and gutter day. While they offered to get us on the schedule sooner, we asked to be scheduled in early November 2024 because it worked better for us.Overall, we’re very pleased with the work done and hope that we’ll be able to work with them in the future for window/siding replacement. Fortunately for us, there were no surprises when they stripped the old roof off, so the final price was as quoted.Photos (Brown roof before; black roof after)
January 10 · Amanda BlackfordSo happy with our new roof! Caesar ran the project and was extremely helpful, walked us through the process and kept us updated. He even returned to make sure we were happy with the results. Very professional from start to finish; a pleasure to deal with - I highly recommend George Keller & Sons
May 02 · Susan ArndtCesar and his crew did an outstanding job. The entire process with G. Keller and Sons was very well organized. About a week before the work started, I received emails about what to expect. Team showed up when scheduled and completed the job in the time frame estimated. The house was well protected from any construction debris and when the clean up was done things were in better shape then before work was done. The roof itself is a vast improvement from the original and really improves the image of the house. I am very pleased with the work that was done and I am very glad I chose George J. Keller and Sons for my project.
July 08 · Tim McCumberThese guys were excellent. Dan Kozlowsky from Keller and his crew took the time to bring my 1980's roof up to modern standards. Shingles, soffit vents, ridge vents, new skylight, eave trim, fascia trim, gutters, downspouts are all new. Soffits and trim were all custom ordered colors that matched the painted house colors. Follow-up and cleanup were terrific.
