From our visit to the factory, then to the installation and cleanup afterward were all very positive experiences The young men installing were polite, friendly and professional. And the pricing of the windows was fantastic. Thank you all at WFO for an outstanding experience!!!! Laurel and Chris K

Based on the reviews he read here on Yelp he decided to go with Alt Builders and their owner Dan. He contacted Dan and was who responded very promptly on a Sunday afternoon. Dan came out the next day to size up the job. He was prompt and very knowledgeable about what Jeff was looking to have done. The patio door was ordered and came in approximately 3 weeks later. Dan and his crew were able to come out to do the job within a couple of days and completed the job in a day and a half just like he promised. They cleaned up and the installation went smoothly. The price was very reasonable and Jeff is definitely going to hire Alt Builders in the future to get some doors installed. He highly recommends Dan for any work or repairs you might need.

We had this company replace a few windows and one sliding glass door. The person who came to do the…read moreestimate was polite and made it easy. Didn't seem to try to oversell us. The lady at the showroom was helpful and to the point. Workers were good. They didn't have enough people on the job to get the sliding glass door upstairs, but they called in extra help and got there right away and got the job done. Everything went well. They did leave some metal outside which was annoying since we have a dog.

The Good: - The…read morepre-sale process was smooth. Jake had an excellent presentation - They were the lowest bidder - The roof looks good and I have not had any issues with it. - Their "A" team came out to correct some issues (the flashing looked like it had been installed by a 4th grader) The Bad: - I was told that a PM would be onsite the entire time. In reality he was on site for maybe 10% of the project - My project was sub-contracted out to a another team and I was NOT informed of this. This became a major problem when I started having issues and could not talk to anyone (the subcontractors did not speak english). Note that Buffalo Fresh Roof is NOT the company you are signing with. The contract is actually with Bors Pros Construction - Within an hour on the first day, the protective tarps had come down and there was debris raining down on my deck and flower beds. When the PM showed up at the end of the day, he said that this could not be helped. Of course, that is garbage - they wouldn't put the tarps up if they didn't have a purpose. Also, this is not what I was told in pre-sales. As a side note, I saw the same sub-contractors working on a project down the street for another company a few weeks later. There were no problems with the tarps on that project. - The roofers decided to try to do a u-turn in my lawn and got stuck (I still have the ruts). They then gave me attitude when I refused to try to pull them out using my truck. - I have damage to my gutters, deck, flower beds and lawn. - I am still finding nails around the perimeter of the house To be fair, the PM did knock off the additional cost incurred in replacing some of the plywood. It wasn't worth what I am going to have to spend in the spring to fix my yard, flowerbeds and lawn - I just wanted them gone.
