Petrolia, ON

I love my windows and they have made such a difference with wind already. The contractor went above and beyond and the salesman was the best one I have ever dealt with. He gave us the bottom line without being pushy. Well done! We will definitely be giving our recommendation to landmark windows.

Leonard Visinki

Renfrew, ON

I ordered my windows and door and expected them to be installed around Sept or Oct. Instead they were delayed until Jan but then the installer got a break and installed them in the middle of Dec. When they arrived they were not exactly what I ordered. The casings were all pine instead of the white vinyl. One of the windows was supposed to be hinged opposite to the others but that didn’t happen. The installers were exceptional but the salesman seemed to have problem getting the order right. The company has done nothing to compensate this mistake and therefore I would have to think about whether I would use or recommend Landmark in the future.

Mary Fountain

Barrie, ON

Great work on the installation of a few window and my doors. Guys were very considerate and did not rush to complete the job. They also took the time to clean up properly. Will definitely have Landmark replace the remaining windows in my home.

Jessica Lemoire

From the moment that the sales rep entered our home we felt at ease with Landmark. He took the time to explain everything in details to us, and was very patient with our children! The installers were very courteous, cleaned up after themselves, and above all did a magnificent job installing our windows and doors. We will definitely be recommending Landmark to our family and friends and we will be repeat customers when it comes to replacing some more windows in our home. Thank you Landmark!

Madison Doyle

Peterborough, ON

The experience with the salesman was great, although we only ever saw him or heard from him once.. after the insane amount of money we spent on the windows and doors I expect at the very least a courtesy call. My initial installation was not a good experience, the installers were very very messy and left me with the biggest mess I have ever had to clean, and did a poor job on a few things. The problem was resolved quickly and someone came to our house within a few days to fix the issues, which we appreciated very much. I was promised that with my new windows I could expect 40% less on all hydro bills, which I have not.. in fact I have used more to heat my house according to my gas and meter readings.. but we will see in time if this continues so I’m not worried about that part just yet. Overall, landmark is knowledgeable and trustworthy. Pricey, but we have always preferred to pay for the better product. I would recommend them, but I would let who I refer what to look out for.
