Extremely happy with my new windows and how quickly they were done. Great job, great price.

Lisa Plant

Recently PerfectFit Installation replaced four basement windows. The job was professionally done, on time and on budget. Professional, knowledgeable staff that know far more than windows and made recommendations of other important work that needed to be done to keep my home secure from the elements. Thank you for the outstanding service!

We recently had some windows replaced and had fascia and soffit work done, and I couldn’t be happier with the results. The quality of the work was excellent and the attention to detail really stood out. You can tell they take pride in doing the job right. On top of that, they were great to deal with — friendly, professional, and easy to communicate with throughout the whole process. I wouldn’t hesitate to recommend them to anyone looking for window or exterior work.

Perfect fit did a couple windows and a patio door on separate occasions and when they're done everything is perfectly put back and cleaned up. Excellent job on the trim work. A company that definately cares about your space.

Abe Harder

We recently had all of the main floor windows and patio door installed by perfectfit and they look and operate perfectly. The installers were professional, organized and courteous. The inside and outside of the house were just as clean as before the work was started. I would recommend perfectfit to anyone who needs their windows or doors replaced.
