Why Choose Us

Why Lakewood, WA Property Owners Choose SGP Waterproofing for Basement Waterproofing

Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.

Licensed & Insured Crews

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

2

Same-Day Local Dispatch

Our Lakewood, WA crews are staffed locally, so a wet basement call doesn't sit in a national queue for a week.

3

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

The Full Scope of Our Lakewood, WA Basement Waterproofing Work

Every Lakewood, WA 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

Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.

Basement

Window Well Drainage

Poor window well drainage is one of the most overlooked Lakewood, WA basement leak sources, and it's often the cheapest fix on the list.

FAQ

What Lakewood, WA 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?▼

We keep the cut as narrow as possible and clean up debris before leaving the site.

How long does basement waterproofing take?▼

Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.

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?▼

Coverage depends on your policy and the cause of the water intrusion — we can document conditions for a claim, but approval is up to your insurer.

Do you offer a warranty on basement waterproofing work?▼

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