Austin Smith, spent the afternoon going over every detail with me and spent most of it working to get me the product I need gor a price in my budget.
I’m a disabled Veteran with fixed income. Austin reworked the numbers and called his company and between the two they worked hard making sure to give me every discount they could, not many will do that for a old disabled vet.
I highly recommend Leafguard for their support and they do have a superior product and please asks for Austin Smith.

Jonathan Arlook View Review

Just contracted for a new Leafguard gutter system. Jake Wilber very thoroughly walked me through the process – explaining their offering, comparing alternatives, showing me the materials they use and how they work, discussing the warranties – really a welcome, detailed review.

While I was ready to do a complete replacement, his explanations and his photographs of my existing gutters helped me choose. Also, delighted the installation could be done roughly within a week, on the day I chose.

Okay, the work was just finished … looks great, raining while they installed and for the next few days, so an immediate test, and they seem to work quite well. They are noisy, but a simple fix using steel wool pads (recommended by one of the installers) fixed that.
