Went Above & Beyond
I am writing this letter to give my highest recommendation for Ener-Tight Windows and Doors.

We needed to replace every window in our 25-year-old house, as we still had all of the original windows. Almost all of the seals were broken and a lot of the wood on the exterior had rotted. We had received quotes from other companies before deciding on this company and realized that we could get more for our money with Ener-Tight. We are extremely happy that we went with this company.

Ener-Tight was highly recommended to us by friends in our neighbourhood who had work done by them approximately ten years ago. They told us that the work was done in a very professional manner and the company has continued to look after them very well over the years.

I was very impressed with every aspect of the process of acquiring new windows, from the time I first met the owner, Mr. Greg Moreland, until the work was completed. Mr. Moreland is an experienced and honest businessman who genuinely wants his customers to have the products that best meet their needs and are best suited to their home.

The workmen were very hard-working, professional, respectful and friendly and went above and beyond my expectations. They are experts in their field and did an outstanding job. They even did a few quick fix-it jobs in our house (without charging me for them) that had nothing to do with the windows!

In summary, I would highly recommend Ener-Tight Windows and Doors. They are professional and trustworthy and do an excellent job.
