The salesman, Massimo came to my house and examined my roof , with a drone, it was icy). Showed me the pictures and discuss the roofs condition. We then discuss options available. Having worked in construction over 4 decades and having shingled many roofs I felt comfortable with what he was telling me. On our second meeting he presented two options and pricing. I liked the price, a contract was signed and everything was was explained in great deal. A little while after that I was notified that the crew could start. The roof was completed in one day by some very hard working guys and clean up was excellent. I highly recommend Massimo and Guardian Home Imprivements.

Fantastic job by Josh and the siding contractor crew from the Chicago area who I would rate 11 on a scale of one to ten. But Guardian did a wonderful job on a complex cedar shake siding project. Couldn’t be happier with the outcome and how I was treated. Guardian helped me solve a roofing problem by diagnosing the issue and coming up with a great plan -fantastic work by Josh and team putting in vented soffits and roof vents, which has rectified the issues. Again, another great job in January 2026, Highly recommend, Guardian.

Joe met with me for an in home consultation recently and was fantastic! He took ample time to address all of my concerns and went out of his way to make a reasonable plan and provide additional resources. Rosio was great as well. She did a follow up call to address any questions and provided more support and resources. There were no pushy sales tactics and I could tell they really have my best interest in mind! I have not started any work with them yet, but was incredibly happy with the exceptional customer service, genuine care, and professionalism of my initial consult and follow ups. I am totally impressed and look forward to working together. Thanks Joe and Rosio!
