Within less than one year from having a new front door installed by Dans, it's been nothing but problems . The wood around the striker broke shortly after install, I called them and they talk to you like you've never used a door before , they put all the blame on us for being too aggressive opening and closing the door and the project manager constantly had to leave multiple times for personal problems (which has nothing to do with the customer- we all have problems in life) ) - all this with a lifetime warranty on the door, which they point out when purchasing but they don't honour it. The hardware on the door never stays tight so every month I've have to re tighten all the hardware (which is absurd ) and they said they would try to fix the broken wood by the striker but they never return your call or show up - I'll be replacing this door before it's even 3 years old because I'm sick of the maintenance required to just keep it operational . Worst customer service I've ever had . Save your money and buy elsewhere. Buyer beware I only gave one star because I couldn't give zero stars

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.

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.

The new door has much more glass area than the old door and provides a great view of the trees in the back yard. Pricing was very competitive.
