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

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

Living in Northern Ontario, we searched for the best option during our extensive house remodel to…read moreget the best windows out there with consideration of durability and energy efficiency. We have some big/huge windows, and considered wood, vinyl, and fiberglass. We dove deep into the NRCAN ratings of window suppliers, and Fibertec checked off all the boxes (being a Canadian Company was a bonus). The windows all installed well and the house is warm and cozy with no condensation on the inside of these triple paned windows. Overall, these windows were an amazing choice and have held up well. Fibreglass (with glass in the name) expands and contracts at a similar rate to the glass panes themselves, so we do not regret our choice! At about the 13-to 14-year mark, we experienced some failures of the seals within approximately 60% of the windows. The first sign is frost between the panes (in the corners) on the coldest winter days (say -20C or lower). In another year, the low-E coating begins to break down, becoming patchy and noticeable. The initial 15-year warranty paid off, as Fibertech has a solid process in place for honouring their warranty and shipping new panes for replacement. The replacement panes are all built with super spacer technology, which is designed to prevent the problem of failing seals. We have new warranties on the new panes and are only 2 years in with no problems noted.

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.
