Why Choose Us

Why Freehold, NJ 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.

1

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

Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.

What We Do

What Our Basement Waterproofing Service Actually Covers

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Basement

Interior Drain Tile

The core fix for most Freehold, NJ basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.

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

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

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

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.

How It Works

From Call to Resolution: How Basement Waterproofing Works in Freehold, NJ

01

Call & Symptom Walkthrough

A quick phone conversation lets us bring the right equipment on the first visit instead of a second trip.

02

On-Site Moisture Inspection

We also check exterior grading and downspouts, since a lot of basement leaks start outside, not inside.

03

Written, Itemized Quote

You'll see drain tile footage, sump specs, and labor broken out separately, not one vague lump-sum number.

04

Installation & Warranty Walkthrough

Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.
