Halquist Stone

In 1929 Swedish immigrant John Halquist purchased a 2-acre curbing quarry just outside of Sussex Wisconsin. With help from his son, Albin “Stoney” Halquist, he grew the small quarry into what is now one of the largest stone companies in Wisconsin by the end of World War II.

Halquist soon realized that Lannon Stone, quarried in the area since the 1850s, had a good reputation for producing high quality lime, curbing, paving, foundation and building stone. This reputation allowed the company to enjoy the postwar building boom, and Lannon Stone became the predominately used material for houses and churches in Milwaukee, Chicago and the northern Midwest. Over the years Halquist Stone became the innovators in the industry with the first to use diamond saws, first to locally market stone from around the country and the first producer to recycle its waste into agricultural lime and crushed stone. This laid the foundation for what is now a successful aggregate business.

Today, whether it’s in our showrooms, quarries or our national distribution channels you’ll find the highest quality building and landscaping stone known to mankind. Because natural stone may be the most versatile product available in building and landscaping, we pay special attention to the details of your plan to ensure that the right stone is specified before the order is placed. Whether you are a homeowner, builder or architect, we encourage you to talk to us very early in the project to discuss the preferred stone for the application you have designed. The team of experts at Halquist can assist you with recommendations that add quality and character throughout the entire project.

Jireh Brick & Stone

Hi, I’m Jason Demler – owner of Jireh Brick & Stone, LLC.

The word “Jireh” is part of a Hebrew name for my Lord and Savior, Jesus Christ. Jehovah-Jireh means “the Lord will provide.”

For almost 11 years I worked at a large company in brick, block, stone and landscape sales and highly value my time spent there. I learned a lot about the construction industry and made incredible relationships with some great people.

In June 2013, I left to make a go of things on my own as an independent masonry and landscape materials supplier, and now work with people like you to help your construction project dreams become a reality.

If you want to see some of the companies I work with, check out the Vendors page.
