We cancelled a contract that we had with another company

We loved your sales approach. Zach was so awesome, no pressure at all. He felt like family as soon as he walked in the door and because of him we cancelled a contract that we had with another company and went with you guys instead.

The work was completed by a crew of three in 5 hours

All work was done professionally and quickly

The installation team was phenomenal

Very professional. Great communication overall in answering questions. I knew which staff handled what so I wasn't handed from person to person. My tenant said the installation team was phenomenal, which gave me tremendous relief.

The skill level was beyond anything I could've imagined.

I was most satisfied with the quality of workmanship, especially where they wrapped the surrounding wood in aluminum. The skill level was beyond anything I could've imagined. The work that Mr.Kim could do was over the top, excellent. Everybody just did their job, they were not needing direction, they were all very...
