JM Inc. Mission of JM Inc: Client satisfaction; by creating an exceptional project experience every time. JM Inc. started in 1993 with Ken Johnston.

During the early years JM worked mostly with custom stone and brick masonry. As the years progressed and the company grew, the demands also changed. Soon JM expanded into other services (such as the Home Service line now offered) to serve the demands of our clients. With the constant changes JM has stayed true to an important value, client commitment. In anything we do, we make sure our clients are satisfied with their experience.

You might know us for our masonry and concrete work, but did you know we do a whole lot more?

It's true! Our team at JM Inc. also tackles roofing, siding, windows, doors, decks, fencing, home remodeling, water mitigation, and more.

We know how much work goes into taking care of a home, especially here in Northern Minnesota. Our goal is to make the repair and improvement process a little easier, with a team you can count on from start to finish.

Have a project on your list? Give us a call. We'd be happy to talk it through with you.

In Northern Minnesota, winter brings plenty of snow, ice, moisture, and freeze-thaw cycles. Existing cracks and damaged areas can give water a place to get in, and freezing temperatures can make some problems worse.

We put together 5 things homeowners should check this fall to help get their concrete and masonry ready for the season ahead.

Take a walk around your home and check your:

šŸ Concrete patios, sidewalks & driveways
🧱 Brick, block & stonework
šŸ  Foundations
🚪 Steps & entryways
šŸ’§ Drainage around masonry and concrete

And if you find something that doesn't look right, you don't have to diagnose it yourself. Send us a photo or give us a call. We'll help you figure out what you're dealing with and what the next step should be.

It looks like winter is sticking around a bit longer, but that doesn't mean you need to wait to complete your masonry projects!

When people hear ā€œwinter masonry,ā€ the first reaction is usually concern. Cold weather and construction don’t always seem like a good mix, especially when it comes to brick and block work. But here’s the important part: it’s not about the season. It’s about control. At JM Inc., when we p...
