Marty Stein was the company representative that came to the house and it was a pleasure to work with him. Very knowledgeable and friendly. Answered all questions and gave us a very reasonable price. We will call him in the future for other projects.

We just had the installation of 13 windows done and are very happy with the way they turned out. Alan and Luis did a fantastic job and we’re extremely professional during the process, they even left the work area cleaner than when they started. Looking forward to doing more projects with this company in the future.

Update after install!

We had the pleasure of having Silas and Ice to do the install of our new Leafguard gutter system. They were top notch professionals answering all of our questions and making sure thing were just as we expected. The did a great job cleaning up when the job was complete and our home looks better than ever. As luck would have it we had a rainy day the day after the install and our days of leaky gutters are over. They worked beautifully!

If anyone is on the fence on the investment take my word for it, you will never regret this!

Chris Stebbins was by far the best rep we have dealt with EVER. Super knowledgeable and friendly, made this decision the easiest we have ever had to make. Hands down the only solution for us! Thanks again Chris and thank you Leafguard for keeping the house and family safe and protected!

Installation went really well and our installers were very helpful in answering all our questions.

I have nothing but great things to say about Silas and Rick who were here today for eight hours. They worked incredibly hard the entire time. They were congenial and polite and explained everything they were doing. My house looks absolutely lovely now with the terratone gutters and clay downspouts. I am looking forward to not having gutter issues anymore. Job well done! These two men are definitely an asset to the Leafguard business. And the business itself is impressive as well. I really liked the prompt and courteous communication from start to finish.
