Waterproofing, Plumbing & Excavation Experts in Shelby Township

Shelby Township is where our shop is and where a lot of us live, so these are the basements we know best. Ranches from the 1970s, colonials from the 1990s, new builds off 26 Mile, all sitting on the same stubborn clay between the Clinton River and the Stony Creek hills.

Shelby Township is home, so here’s what we actually see

We’ve been working out of Shelby since 2004. That means our trucks are on Van Dyke and 23 Mile every day whether there’s a job here or not, and it means a fair amount of our work is for people we run into at the gas station afterward. You fix a basement differently when you know you’ll see the owner again.

Shelby has grown a lot. The township had about 65,000 people in 2000 and close to 80,000 by 2020, spread over roughly 35 square miles. That growth came in waves, and each wave left a different kind of basement behind.

The older south end

Down near Utica and along Auburn Road, a lot of the houses are 1960s and 1970s ranches and tri-levels with concrete block walls. Block leaks in a few predictable ways. Water seeps through the mortar joints, fills the hollow cores, and weeps out at the bottom where the wall meets the floor. In a wet spring you’ll see a dark band about a foot high along one wall and a white chalky residue above it.

For these, an interior drain tile system usually makes more sense than digging outside. We cut the floor along the wall, drill weep holes into the bottom row of block so the cores can drain, lay pipe in stone, and run it to a sump. It’s not glamorous. It works.

The 1990s and 2000s subdivisions

Further north it’s mostly poured-wall colonials, the kind you’ll find in subs like Cherry Creek and Huntington Park. These basements are deeper, they have egress windows, and the walls are solid concrete. They leak at tie-rod holes and at hairline cracks that run up from the floor, and almost all of those can be handled with crack injection from the inside.

The bigger issue in these neighborhoods is the yard. Backfill settles for years. By now a lot of lots have gone from sloping away from the house to sloping toward it, at least in the first few feet, and that is often the entire problem. If a downspout empties into a sunken flower bed by the foundation, start there. Sometimes a crack is just a crack and the dirt is the real culprit.

Where the water goes in Shelby

The Clinton River runs along the south side of the township and the Middle Branch cuts across from Washington Township on its way east. In the northwest corner a slice of Stony Creek Metropark crosses into Shelby, and the land there gets rolling instead of flat. Most of the township, though, is flat clay that doesn’t let water go anywhere fast.

That makes storm intensity matter more than storm totals. In August 2020, a short, intense storm flooded units at the Windmill Pond condos on 22 Mile, and residents there were dealing with it again in 2023. Officials called it a localized storm of unusual intensity. Those are exactly the storms where a sump pump without a backup gets overwhelmed or loses power.

Mostly it changes how fast we get there and how well we know the ground. We've worked in Shelby subdivisions since 2004, so we've seen how the 1970s block-wall ranches near Utica behave next to the 1990s poured walls further north. On a stormy night, being a few miles away instead of across the county is a real difference.
It's usually small things. One house has gutters that dump at the corner, the other has extensions out ten feet. One lot was graded a few inches higher when the sub was built. One has a sump pump that's twenty years old. On the same clay, those details decide who gets wet. We'll point out the cheap fixes first.
It depends on your bylaws and where the water came from. Units at Windmill Pond on 22 Mile were reported flooded in August 2020 and again in 2023, and it took a while to sort out who owned what. We can inspect, document the entry point and give you and the association the same written findings, which usually speeds up that conversation.
Most of the township sits on heavy clay that holds water like a bowl. Toward the northwest, near Stony Creek Metropark, the ground gets hillier and there's more variation, which can help or hurt depending on where your house sits on the slope. Clay isn't a death sentence. It just means the water around your walls doesn't leave quickly, so drainage and a working sump matter more.
Block walls from that era leak through the mortar joints and fill up inside the hollow cores. You'll see white powder on the wall, a damp band near the floor, or a horizontal crack partway up if the clay has been pushing on it. Interior drain tile with weep holes drilled into the bottom of the block handles the water. A bowing wall is a separate conversation.
Yes. Our regular hours are 8am to 8pm every day, weekends included, and we take emergency calls any time of night. For a non-emergency estimate in Shelby we can usually find a slot that week, and since we're local, an evening visit after you get home from work is easy to arrange.
Replacing or repairing a sewer lateral, and some backwater valve installs, need a permit and an inspection. We pull those ourselves and schedule the inspector. If someone offers to dig up your sewer line without a permit, that's a red flag.
Not very. We clean the crack, set small ports along it, seal over the surface, and pump polyurethane or epoxy in from the bottom up. It takes a couple of hours and you'll see a seam of sealer on the wall when we're done. Nothing gets dug up outside.
Yes, financing is available through Enhancify. You can check what you qualify for without it affecting your credit score. Plenty of Shelby families split a bigger job, like drain tile on three walls plus a new sump, into monthly payments. We'll walk you through it when we hand over the estimate if you want.
Not necessarily. If you've never had sewage come up a floor drain, and you have no finished space down there, it's optional. Where it makes sense is a finished basement on a street that has had backups before. We'd rather tell you to skip it than sell you one you'll never need.
