A Drive to do Things Right

"I love my job and the good feeling I get when I solve a problem for someone else."
- A Dillman Brothers Employee

Somebody wrote this quote on a whiteboard in our main conference room. We liked it so much that we chose to leave it there as inspiration.

This statement actually sums up the reason we went into business in the first place back in 1972.

Our company was started by a father and his four sons. Currently, our third generation is working alongside our team of nearly 40 "adopted family" or extended family members. Without a doubt, Dillman Brothers has been a family tradition from the beginning.

We take great care in selecting the companies that manufacture our building products. We choose to protect you with the brands that have the industry's best certifications and guarantees.

You can rest assured knowing that we'll do exactly what we say we are going to do. And, we'll do it on time!

With Dillman Brothers, you'll be partnering with the first company in Central Illinois to become preferred James Hardie siding installers.
