Order two entry doors and an 8' sliding patio door back in September 2020 with a very large upfront deposit and it is now May 2021 and we are still waiting for the doors and the installation.
Since the purchase to Nordik the service has fallen downhill. I'd suggest looking elsewhere because I'm forced to now chase for my refund or my doors

OK but not great and some frustrations. Warranty is great but work and communication were careless at times. Service had to come back several times mainly since the glass itself had markings or defects and to fix sloppy caulking. At least those people were friendly and were able to fix over time problem areas. At install time no tarps or covers were used and sharp pieces of metal from cutting edging were all over my property. I'm glad I found them before my kids did, there were over 20 sharp metal triangle shaped pieces. Also plastic cut off tips from caulking were all over my property as well

After the installation of over 7000$ for three new doors in January 2020, I realized that a gap was left between the frame and the fascia . I contacted QSI to have the problem resolved and the woman told me they were shut down for COVID-19 but as soon as they start working again I will be a priority. After opening I contacted the service department leaving numerous messages. It has taken them 3 weeks to get back to me and now they are unable to work around my schedule to fix the problem they created 6 months ago. Also the woman told me they are too busy because they are merging three companies

Will never use again and not recommend anyone to this so called professional window place
We had our consultation he was over an hour late.
Measured all the windows twice when they finally did show almost 2 months later they didn't have one window. It wasn't out on contract after measuring twice.

Well you know the saying " you get what you pay for". Well with QSI that should be their motto. The windows and doors are more pricier than other places but well worth it. Tripple pane windows oak trim, they look great. We bought a bow window in the front that's 10 feet wide. When it was installed I had people stop and say your window looks amazing, and I had to agree. Great place would, and do always, recommend them.
