Mark and his team did a terrific job and I could not be more pleased with the final work! Throughout whole siding installation process I was kept well informed about the progress and what will be next steps in the process. I'm living in Arlington Heights and anyone who is looking for great siding contractor can stop by my house and check their amazing work. I also plan on hiring them again for another siding project. That would be my parent's home. 🙂

I researched over 30 companies, and had 5 come out to my house to give me estimates to install new vinyl siding. I ended up going with Smardbuild, and I am very happy that I did. They showed up on time, and finished the entire job within a week. And the quality of the work is the best part. They are perfectionists! I have never seen attention to detail like this. They even went above and beyond the job requirements. They installed aluminum flashing around my sliding glass door to make it look nicer, and that was not even part of the job. And to top it off, they installed 2 new wall lanterns that I bought at Home Depot.

We used Mark and his Smardbuild team to replace our roof, soffits, fascia, siding, upstairs windows, gutters and front door. All work performed is top notch. We went with Hardie soffits and fascia since we had prior issues with carpenter bees drilling holes in our old, wooden soffits. In my opinion Smardbuild is the best with Hardie products. Everything looks great. It took us a while to finally settle on a color for the siding and Smardbuild was quite patient with our process. After having issues with contractors in the past, it was refreshing to work with such a professional team that actually cares about the quality of their work. Thanks Smardbuild.
