Darryl and his team did an amazing job for us. They were thorough, highly communicative and very professional. They worked around our schedule and needs. Timelines were quick and we received regular updates. It was a seamless process. When they were finished you couldn’t even tell they had been here with how well they installed the windows and finished the area around them. We have more to do later this year and I can’t imagine going anywhere else.

Just wanted to thank you and your team once again for the great job on our windows. It was a pleasure to meet and work with all of you and we will definitely recommend you to our friends and family. All of you were great to work with. You explained everything so well right from the start, with the difference between inserts and completely new windows to how to remove them for cleaning. Everyone was professional and easy to get along with. They thought of the customers comfort when installing the new windows by closing the doors to keep the cold out.

Again, a great job and thanks again

Darryl and his team redid all of the siding, window capping, and eavestroughs on our (very old) house. When Darryl first came by to evaluate and provide a quote, he was incredibly knowledgeable, professional and did not try to sell us on anything. His team were so friendly, kind, and professional. Despite it being a big and challenging job (also being done in the winter), they kept the job site clean and tidy everyday, and were very considerate of our neighbours. The final product is above and beyond what we expected! Neighbours and strangers have stopped in front of our house to compliment how amazing it looks. We have not hesitated to recommend Darryl and his team to everyone who asks about our house.

Darryl and his crew went above and beyond. From the initial quote to the final piece installed. I had 6 windows and board and batten siding installed, the job they did met all my needs and even fulfilled any special requests I had. Darryl kept me up to date with the timeline, I was not disappointed. They cleaned up after the job, you would not even know they were here. The price he quoted was comparable to other quotes I received, I would recommend permanent siding and windows, you will not be disappointed !!

Back in the Spring of 2025 we contacted 4 vendors to have our home re-sided and I'm glad we went with Permanent. No sales rush, no excuses, no delays and quality work.
