Get Started

“Leland sided our house about 3 years ago, and we liked them so much that we had them back to replace our roof this past Summer. Tony & his staff are quick, efficient, and thorough. They show up when they say they will, and complete projects within the time frame given at the time of contracting.”
- Janet-Marie R.

“I don't even know where to begin. We (foolishly) hired another siding company and wasted a full year of a half sided house that rotted more and more as the time went by. Once we were able to finally hire another company, we chose Leland and it was the BEST decision we have made! They could not have been more professional! They came in, fixed all of the rotted wood and mess left behind from the other company, and left us with an amazing finished product in ONE WEEK. I cannot recommend them enough. ”
- Leanne M.

“Leland just completed siding and doors on my house. Tony and his crew did an excellent job. From sales to final clean up they went above and beyond. Their attention to detail in workmanship was refreshing. This was a large project for us but I soon realized that I didn't need to micromanage it. Tony's team will deliver what they promise. I have to admit they left my yard cleaner that they found it!”
- Dave B.
