Need Windows or Doors Replacement?

What Our Clients Say

I am in love with the new replacement windows installed!! I had to replace the old since they were worn out and less cost-efficient but I’m so glad I did. I didn’t know what to do at the start but luckily the very nice staff of Merivale Windows helped guide me into choosing the perfect fit. Everything was done flawlessly, on time, and without any issues! I will definitely order from them in the future if the need arises.

Randy Jacobs

A couple of weeks ago I ordered a patio and entry door replacement and, let me tell you, I was not disappointed by the results. I’ve done some refurbishing before but never has a renovation worked out so smoothly. The doors match the style of my home perfectly and the installation was done impeccably. Needless to say, I am very satisfied with the end product.

Trevor Rhodes

I (and my wallet) am extremely satisfied with my decision to buy whole house windows. I was thinking of a way to cut down on heating bills, and these just so happened to come into my life. I am extremely content with the energy efficiency improvements they provide. I would most certainly recommend Merivale Windows to everyone.
