Waterproofing, Plumbing & Excavation Experts in Farmington Hills

Farmington Hills isn't lake country. It's about 84,000 people on the clay of the Rouge River headwaters, where the main branch of the river starts as two county drains. Most of the subdivisions went up between the late 1950s and the 1990s, so we see everything from block-walled ranches to poured-wall colonials and tri-levels, and the water problems follow the decade the house was built.

Farmington Hills basements sit on the Rouge headwaters

The main branch of the Rouge River starts in Farmington Hills, where the Minnow Pond Drain and the Seeley Drain come together. Other tributaries gather nearby, and by the time the river reaches Dearborn, the Rouge has become the most built-up watershed in Michigan. If you live here, you live on the ground that feeds it.

That ground is mostly clay, rolling in places and flat in others. It holds water against a foundation for days after a storm, swells when it’s wet, and shrinks and cracks in a dry August. Unlike the lake townships to the north, the problem here usually isn’t a high water table. It’s water that can’t drain away from the wall.

The age of the house tells us most of what we need

Quaker settlers came in 1824 and the area was called Quakertown for a while, but the city as most people know it is a postwar suburb. It incorporated in 1973, and most of the subdivisions we work in date from the mid-1950s on.

Late 1950s to early 1970s

Neighborhoods like Briar Hill, north of 13 Mile and west of Farmington Road, and Old Homestead filled in during these years with ranches, colonials and tri-levels. Most have concrete block basements. Block leaks at the joints and holds water in its hollow cores, and the clay drain tile from that era is usually partly plugged by now. These are the houses where interior drain tile and a sump do the most good.

Tri-levels deserve their own mention. The lower family room is half underground, often on a slab with no drainage under it, and it’s the room that floods.

Late 1970s through the 1990s

Farmington Square, north of 9 Mile between Haggerty and Halsted, went up between 1978 and 1987. Halsted Estates near Grand River is mostly 1980s and ’90s. Houses from these years are mostly poured concrete. The walls are solid, and leaks tend to be one shrinkage crack, a tie-rod hole or the spot where the water line comes through. One crack, one injection, done. We’ll tell you if that’s all you need.

Sewer backups are a separate problem

When a floor drain backs up during a downpour, that’s sewage, not groundwater, and it calls for a different fix. Farmington Hills is served by the county’s Evergreen-Farmington sanitary system, which has had enough overflow trouble that the county built a corrective action plan and a large overflow storage project around it. In the worst storms, public lines fill and push back toward the lowest drains on the street.

Two things protect you. A camera inspection of your own line comes first, because a cracked or root-filled lateral from the 1960s can cause backups on its own. Then a backwater valve, which lets sewage leave the house but won’t let it come back in.

What we’d check first

Before any of that, look outside. Clay lots settle around a house over decades, and in a lot of older subdivisions here the ground now pitches toward the foundation. Downspouts that empty a foot from the wall feed water exactly where you don’t want it. Fixing those costs very little and sometimes ends the leak. Run the extensions out at least six to ten feet, and make sure the patio or walk next to the house hasn’t sunk and started tipping water back toward the wall.

We’re about 40 minutes from our Shelby Township shop and open 8 to 8 every day. The estimate is free.

Briar Hill went up in the late 1950s and early '60s, so most of those basements are concrete block. They tend to leak along the mortar joints, at stair-step cracks near the corners, and at the floor line where water drains out of the block cores. If the original drain tile is clay, it's probably partly plugged. Interior drain tile and a sump usually fixes it for good.
Tri-levels put that lower room only partly below ground, often on a slab with no drain tile, and it sits right at the height where water collects against the house after rain. The basement section is deeper but usually has drainage. Check the grading and downspouts on the wet side first. If water still gets in, a drain along that wall tied into the sump usually solves it.
It's heavy. Much of the city sits on clay that holds water against a foundation instead of letting it drain away, and it swells when wet and shrinks in dry summers. That movement opens cracks and pulls the grading out of shape over the years. It's why we lean toward drainage here rather than sealers. Water in clay doesn't leave on its own, so you have to give it a path.
It might be. Farmington Hills is served by the county's Evergreen-Farmington sanitary system, and in very heavy rain the public lines can fill faster than they drain, so sewage comes out at the lowest drains in the neighborhood. A backwater valve on your line stops that reverse flow. We'd also run a camera down your own lateral, because a cracked or root-filled pipe causes the same symptom.
It's about 40 to 45 minutes from Shelby Township, usually straight across on I-696. We're open 8am to 8pm every day, Saturdays and Sundays included, for regular appointments and free estimates. Emergency calls for flooding or sewer backups are answered around the clock, so a Sunday night storm still gets a person on the phone.
Often nothing. Poured walls from that era are solid, and many never leak. When they do, it's usually one shrinkage crack running down from a window corner, a tie-rod hole, or where the water line comes through. Each of those is a small injection job done from inside. If your basement has been dry for thirty years and one spot started weeping, that's what we'd expect to find.
Rarely isn't never, and the outages here tend to arrive with the summer thunderstorms that fill a sump pit fastest. Pumps also fail on their own, usually a stuck float or a burned-out motor, often with nobody home. A battery backup on its own switch plus a high-water alarm is a small cost next to redoing a finished basement.
Yes. The 25-year warranty on our waterproofing systems covers materials and labor and passes to whoever buys the house. You'll get the paperwork plus a written note on what we put in and where it runs. In a city where so many houses are fifty-plus years old, buyers' inspectors go straight to the basement, and that folder helps.
Yes, through Enhancify. The estimate is free. In Farmington Hills the scope usually comes down to wall length, whether the basement is finished, whether a tri-level's lower room is involved, and whether the sewer line needs a valve or repair at the same time.
