Most contractors are happy to earn a customer once. Thompson Trenchless & Hydro Jetting earned one for two decades. Over roughly 20 years, one Wyandotte-area property owner has called Thompson back again and again — for his own home, for the apartment buildings he owns, and for his daughter’s house. The work has spanned basement water protection, crawl-space drainage, and sewer repair, and it has all come from the same trusted team.
A finished or storage basement is one of the most water-vulnerable parts of any Michigan home. Two things threaten it: municipal sewer backups pushing water up through the floor drain, and groundwater seeping in during heavy rain and snowmelt. The homeowner needed protection against both.
As a property owner, the customer also had two apartment buildings whose crawl spaces were taking on water. Standing water under a rental building isn’t just a nuisance — it damages structure, invites mold, and creates tenant complaints and liability. Both buildings needed a real drainage solution, not a temporary fix.
On top of his own properties, his daughter’s home developed a sewer problem needing professional repair. When it’s family, you don’t gamble on an unknown contractor — you call the company you already trust.
For the basement, the team installed a backwater valve together with a sump pump system. The backwater valve is a one-way gate that stops city sewage from flowing back into the home during a backup, while the sump pump actively removes groundwater before it can pool. Together they cover both failure modes — sewer-side and groundwater-side — in a single, coordinated system.
For the two apartment buildings, the crew installed a sump pump and drain tile system in each building’s crawl space. Drain tile (a perforated pipe in gravel, the same principle as a French drain) collects water before it reaches the crawl space and channels it to the sump, where it’s pumped away from the foundation. It’s the difference between a chronically damp building and a dry, protected one — and on a rental property, it protects both the structure and the owner’s bottom line.
At the daughter’s home, the team handled a sewer service repair. Where possible, Thompson favors trenchless methods and always leads with camera inspection so the diagnosis matches the actual problem — no guessing, no unnecessary digging.
Every job starts with figuring out what’s actually wrong. Camera inspection and a straight explanation of the options come before any recommendation — which is exactly why customers describe the team as “knowledgeable” and trust their judgment across very different jobs.
A basement, a rental crawl space, and a family sewer line all call for different solutions. Instead of one-size-fits-all, each property got the system it actually needed — backwater valve and sump pump here, drain tile there, sewer repair at the third.
Thompson has built its name on quality, tidy, code-compliant work. That standard held whether the job was a private basement or two occupied apartment buildings.
The team treats each visit as part of an ongoing relationship. That’s why, when the next problem came up — a different property, a different service — the customer already knew who to call.
The basement gained protection against both sewer backups and groundwater, and both apartment crawl spaces went from taking on water to staying dry — protecting the structures and the owner’s rental income.
The sewer service repair at the daughter’s home restored dependable flow, handled by a team the family already trusted.
The clearest result isn’t any single job — it’s that the same customer has chosen Thompson Trenchless “multiple times in the last 20 years,” across three properties and several service types, and still recommends them to anyone who asks.
From a single-family basement to a multi-unit apartment complex to a family member's home, one licensed team handled it all. That continuity means less explaining, faster diagnosis, and a company that already knows your properties.
Backwater valves, sump pumps, and drain tile aren't emergency call-outs — they're prevention. Thompson's willingness to fix the root cause (and keep costs "reasonable," in the customer's words) is what turns a one-time repair into a 20-year relationship.
and all Wayne and Monroe County communities.
A backwater valve is a one-way valve installed on your sewer line that lets waste flow out but blocks municipal sewage from flowing back into your home during a city sewer backup. It’s one of the most effective ways to protect a basement — learn more about our sewer backup solutions.
If your crawl space takes on water after heavy rain or snowmelt, yes. Drain tile collects groundwater before it pools and routes it to a sump pump that removes it from under the structure — preventing mold, wood rot, and foundation damage. See our French drain and drain tile service.
We start with a camera inspection to pinpoint the problem, then use trenchless sewer repair where the pipe condition allows — rehabilitating the line through small access points instead of a full excavation, preserving your landscaping and driveway.
Yes. We serve single-family homes as well as commercial and multi-unit properties like apartment buildings, adapting the solution to each property’s needs.
Yes — we provide 24/7 emergency response throughout Wayne and Monroe Counties, typically arriving within 2–4 hours for sewer backups and urgent failures.
