Why Holly, MI Property Owners Choose SGP Waterproofing for Basement Waterproofing

We've seen enough Holly, MI basements to know that a wet spot in one corner rarely tells the whole story. Before we recommend drain tile or a sump upgrade, we trace the water back to where it's actually entering, not just where you noticed it.

Licensed & Insured Crews

Every technician carries full state licensing and liability coverage before they ever step into your basement.

2

Same-Day Local Dispatch

Most inspection requests get a same-day or next-day appointment, not a two-week wait.

3

Flat-Rate Pricing, No Surprises

No hourly billing and no change orders once your basement floor is already open.

4

Moisture-Mapping Equipment

We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.

What We Do

What Our Basement Waterproofing Service Actually Covers

Every Holly, MI Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

Basement

Interior Drain Tile

We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

The cove joint where the floor meets the foundation wall is one of the most common Holly, MI leak points, and we seal it as part of every interior system.

Basement

Vapor Barrier Wall Membrane

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.

FAQ

What Holly, MI Customers Ask Us Most About Basement Waterproofing

How much does interior drain tile installation cost?

Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.

Will you cut into my basement floor?

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

How long does basement waterproofing take?

Most residential interior drain tile and sump installations finish in one to three days depending on basement size.

Do I need a sump pump if I'm just sealing a crack?

Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.

Is basement waterproofing covered by insurance?

We provide photos and moisture readings that many Holly, MI homeowners have used to support a claim.

Do you offer a warranty on basement waterproofing work?

Warranty terms are often transferable if you sell the property later.
