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

We had an outstanding experience with Renewal by Andersen. Truly a league apart from the…read morecompetition. It was a pleasure to work with Sales Rep (Karan) who answered all of our questions and had lots of time for us. Then, there were the installers (Alec and Tim) who were extremely professional, skilled and polite. Outstanding. Finally, Project Manager Jim was also extremely knowledgeable and stayed with with us through the whole process. All in all, these 4 people really made our experience with Renewal by Andersen an outstanding one. Highly recommend

have received your offer and the contract and have reviewed them…read more After very careful deliberation, I feel that I am not comfortable with dealing and doing business with you Though price is a consideration, there are many other factors which led me me to take this considered decision There were so many red flags - some among them, twisting facts, attempts at disinformation, false accusations, high pressure selling, contradictions in the contacts, lack of protection for my deposit, lack of trust and belief in me as the customer This may not just you but maybe this is the corporate philosophy and culture, and business model of the company Site visits, sales call and marketing and advertising all are just tools of the sales proceeds, and a means to secure business, and NOT a favour to the customer that it has to be cited as a reason for the costs and pressure It is rather unfortunate, as I really wanted to do business with you thinking that I would be dealing with reliable professional, ethical company, which is customer centric, understanding and respectful of its customers I also received TOTALLY opposing reports and recommendations bout some windows from the two representatives. Does not provide any level of comfortin theprofessionalism and assessment! you MAY have good products but that is only a small Part of a business relationship. I hope this could be the trigger to review and revise your business model and ethics I wish you all the best to you and the company and hope that its customers get their money worth and respect that they deserve, as THEY are reason for your very existence of the company

I got a quote from Windowfix.ca to repair the mechanism on four of my windows. They quoted me $815…read more which I thought was a bit steep, but nevertheless better than replacing the windows. When the technician got here he revised the quote because I had reported the four cranks were broken, whereas on some windows it was the lever mechanism. So the quote went to $1288. Reluctantly I agreed although some of the work actually looked simpler. When I reviewed the work, I found that one of the brackets was loose, and asked could he replace that bracket too. The brackets had been quoted at $25 bucks each. The technician went to the truck and returned to tell me he didn't have the bracket. I said no problem, come back when you have it. He told me "Well that's another visit so it will be $195. dollars to return. Now I was about to pay $1288. for two hours work and about fifty bucks worth of hardware, and now I had to pay another two hundred bucks for another service call because he doesn't have the right parts on the truck. A bit outrageous, all in all. I felt kind of gouged. I won't use this service again.

If you want to have your windows upgraded, but not replaced if there's things to be fixed around the window, they can do that and it's it's awesome because I cannot afford to buy all brand new windows so it was more or less cosmetic for a lot of the stuff I needed done. Great job guys. 10/10 for them.

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.
