Why Choose Us

Four Reasons Our Basement Waterproofing Clients Don't Call Anyone Else

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

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

3

Flat-Rate Pricing, No Surprises

You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.

4

Moisture-Mapping Equipment

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

What We Do

The Full Scope of Our Union, OR Basement Waterproofing Work

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

Basement

Interior Drain Tile

The core fix for most Union, OR 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 Union, OR 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

Our Four-Step Basement Waterproofing Dispatch Process

01

Call & Symptom Walkthrough

You describe what you're seeing — a wet spot, a musty smell, standing water — and we get a rough read on urgency before dispatching anyone.

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

You'll get warranty paperwork and a walkthrough of how the system works so you know what to expect going forward.
