Southfield basement waterproofing FAQ
Updated October 19, 2026
Are you a waterproofing contractor?
No. We're a referral service. We take your request and hand it to one independent contractor who works in Southfield. They give the estimate and do the work under their own license and warranty.
What does the referral cost me?
Nothing. The contractor pays us for the introduction. You pay only the contractor, and only if you hire them.
How many companies will call me?
One. We don't sell your request to a list of bidders.
Do you have a Southfield office?
No office. We're an online referral service that works with contractors serving Southfield and nearby Oakland County cities.
My basement only leaks in heavy spring rain. Is that a waterproofing problem?
Usually yes: seasonal leaks mean the water table or saturated clay rises above the floor level a few times a year. The fix can be as small as grading and downspouts or as large as interior drain tile; a contractor can tell which.
Water comes up through the floor drain, not the walls. Who fixes that?
That's sewer surcharge or a sump tied to the sanitary line, common in older Southfield homes. A plumber or waterproofing contractor can install a backwater valve, disconnect footing drains from the sanitary sewer, or re-route the sump discharge outside. Mention floor-drain backups in your request so the right trade comes out.
How long does interior drain tile take?
Most 100-to-150-foot perimeter jobs take two to four days, including concrete cure time before the new floor can be walked on.
Is a permit required?
For sump and sewer-connected work in Southfield, yes, a plumbing permit through the city's online BS&A system. The contractor should pull it.
What should I ask the contractor?
Their state license number (verify on LARA), proof of insurance, a written transferable warranty, linear footage and pump model on the estimate, and who handles the permit.
What if I don't like the estimate?
Decline it. There's no obligation to the contractor or to us, and you're free to get other bids.
