Siding Contractors in Pontiac

“Great experience working with Grennan Construction. Like most older homes, when you want to update something, it can be like peeling an onion. Grennan Const. gave our home the exterior update we wanted, while also fixing the problems we knew we would discover under the surface. Their siding crew was friendly, efficient, and professional. And, Brandon, I believe Grennan's main framer/carpenter and overall problem solver, rebuilt several areas for us. He was easy to work with and I'm very confident in the work he and the crew did on our home. And finally, communication with Dan who managed the job and Fred who I initiated the job with was excellent. Everything went smoothly. The estimate grew as problems were found, but it was expected, and we wanted them addressed. I recommend Grennan Construction.“

“We had some cracked siding reached out to them and very professional from the start. Trevor showed up with quote with options and did absolute professional job. It was very hot couple days but they still kept their promises and finished the work. Thanks Trever and appreciate it. Great front office as well.“

“Upon initial phone call to Roof One we spoke w/ Raine who was courteous & informative. Mark was prompt & he provided a professional & thorough roof assessment. Tracy (office mgr) followed up post roof install completion re: customer concerns & questions. She was caring & friendly. The roofing crew who did a complete roof tear off & new installation were coordinated, hard working & timely. They did a great job! Would highly recommend Roof One to anyone looking to have a roof assessment & install.“
