Hello Everyone…I am one of the Sales Representatives for LeafGuard. I want you all to know that we treat every home as our own when we come out to do an inspection for you. Whether you choose our product or not, we want you to be fully aware of everything that is happening with your home. We are in the business of solution selling, not a temporary fix which costs you more money in the long run. You have a debris problem, it’s solved. You have a water management problem, it’s solved. You want to stay off a ladder, it’s solved. Let me or one of the other sales reps come to your home and help you make an educated decision. We look forward to seeing you!

I love how my shower turned out! Fast turn around and completion time along with precise and dedicated measurements and outcomes. Haven’t had any issues, everything was installed exactly how we discussed it so I have no issues to make. 10/10 already recommended to my mother who will soon be a customer of YHIC as well, shoutout to Arlen and huge shoutout to the guy who actually came and installed my new bath and shower.
