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.

They did leave some metal outside which was annoying since we have a dog.

They came out promptly and helped me out when one of the windows shattered out of my business and I literally could not go home until it was fixed. I spent a lot of time guarding the hole in the building where the window once was until Guelph Glass showed up and saved the day! They have done not only big jobs for me, but also tiny ones as well. Once I had them put a piece of glass into a locket for me and they did it cheerfully, even though I'm sure it was a pain in the butt, and frankly, not even worth their time to do. AND they even gave me a FREE box of glass once when I asked them for some of their extra unusable pieces for an art project I was working on. So I HIGHLY recommend Guelph Glass for your biggest projects and also your smallest. They're fast, friendly and fabulous!
