STRUCTURAL ODOR REMEDIATION · CALIFORNIA

Concrete Odor Proofing℠ Service

Pet urine soaks into concrete slabs.

We seal it at the source.

Garage, basement, or converted slab — pet urine penetrates porous concrete and keeps off-gassing into the room. We dry and seal qualifying slabs with our Odor Encapsulator before new flooring or coating goes down.

CONCRETE ODOR PROOFING

5-YEAR WRITTEN GUARANTEE

BEFORE YOU COAT OR COVER IT

Coating or covering the slab? Seal the odor first.

What odor proofing is

Drying and sealing qualifying treated concrete with our Odor Encapsulator so embedded pet-urine odor is contained — backed by a written 5-year guarantee on qualifying work.

Epoxy or flooring traps it

Paint, epoxy, or new flooring over a contaminated slab doesn't remove the odor — it covers it, and the smell works back out through edges, cracks, and control joints.

Seal the odor first, then coat.

THE REAL PROBLEM

Why the smell comes back from a slab

Concrete looks solid, but it's porous — urine wicks into the capillaries of the slab and soaks into the sub-slab soil below. Surface cleaning only treats the top. The residue left inside the concrete reactivates with humidity and warmth and keeps releasing odor into the room.

If the smell keeps coming back, the source was never sealed — it's still inside the slab.

CROSS-SECTION OF A SLAB

Room air — odor released with humidity & warmth

Slab surface — what surface cleaning reaches

Concrete capillaries — where urine wicks in

Sub-slab soil — residue soaks in below

DIY REALITY CHECK

Why every DIY fix reaches its limit

Concrete hides what has soaked into it. Each of these has its place — a urine-saturated slab isn't one of them.

Bleach & vinegar

SURFACE ONLY

Clean the top of the slab but don't reach urine that has soaked into the pores and the soil beneath.

Enzyme cleaners

WRONG DEPTH

Built for fresh surface accidents; they can't penetrate a saturated slab to the full depth of contamination.

Pressure washing

ADDS WATER

Drives moisture deeper into the slab and sub-soil — indoors, that makes off-gassing worse.

Acid etching

OPENS, DOESN'T SEAL

Profiles the surface but leaves embedded odor behind, and can drive residue deeper.

Paint / epoxy over it

TRAPS IT

Coats the surface without addressing the source; odor returns through seams and cracks.

Neutralize, dry, then seal

We reduce and treat the contamination, dry the slab, and seal it with the Odor Encapsulator — not pour more liquid on it.

THE PROCESS

Here's how we seal a contaminated slab

No surface patches. Your inspection determines which steps your slab actually needs.

1

Inspection

UV black light and moisture meters map the contamination across the slab, cracks, and control joints — with an itemized estimate before any work begins.

2

Identify contamination

We locate affected zones, cracks, and control joints where urine traveled and pooled.

3

Clean & treat

We reduce and neutralize surface contamination on the slab.

4

Dry the slab

We test moisture and dry the slab with professional equipment before any sealing begins.

5

Odor Proofing

We apply the Odor Encapsulator — our odor proofing sealer — to the qualifying treated slab.

THE ODOR ENCAPSULATOR — OUR ODOR PROOFING SEALER

At the end of this process, the odor in the slab is contained or removed — not covered.

Penetrates the prepared concrete

Bonds to and seals the slab surface

Contains residual contamination in place

Helps keep odor from rising into the room

REAL ODORXPERT CONCRETE WORK

WHERE IT SHOWS UP

Where concrete odor shows up

Garages

The most common concrete odor job — pets kept in the garage, or prior-owner contamination soaked into the slab.

Basements

Below-grade slabs hold moisture that reactivates urine odor on damp days.

Converted garages & ADUs

Living space built over an untreated slab brings the odor up into daily use.

Patios & sunrooms

Enclosed slabs that became interior rooms, still carrying old contamination.

ODORPROOF℠

5-YEAR WRITTEN GUARANTEE

ODOR PROOFING

The Odor Proofing Guarantee — 5 Years, Written

Qualifying slabs treated with our Odor Encapsulator are backed by a written 5-year guarantee, subject to the documented treatment scope and written terms.

What odor proofing does and does not do: it addresses pet-urine odor in the specific concrete we treat. It does not make the slab impervious to future pet accidents or to odor from other sources.

The guarantee does not apply to inspections, estimates, oxidizer-only treatments, or allergen services.

Jody was incredibly knowledgeable and prompt. Great communication. Hard working crew. Fixed my problem completely which ended up needing sub floor to get partially jackhammered out and leveled again with concrete as well as drywall replaced in some of the corners. I thought his pricing was incredibly fair. So happy we found him in time for our new flooring to go in. Highly recommend.

My new home had the worst cat urine smell in garage and guest bedroom which we thought was impossible to get rid of. But Jody and his team performed a miracle that we thought was impossible! So happy I used their service!

Jody and his team came to clean up a surprisingly difficult cat urine/spraying issue left behind by a former tenant. We had tried everything: multiple cleanings, odor killers, etc. Nothing worked. It wasn't until OdorXpert came by that we understood the extent of the damage: they pulled the mop boards, some of the sheetrock and flooring, as well as several doors, then repaired, replaced and sealed the areas that the smell was abated. Thanks, guys! What a difference you made.

FAQ

Questions, answered

Can you seal urine odor in a garage slab?

Yes — garage and basement slabs are common jobs. We treat, dry, and seal the qualifying slab with our Odor Encapsulator.

Can I epoxy or tile over it after?

Yes — once the slab is treated, dried, and sealed, your coating or flooring goes over a sealed base.

What if the odor is in the soil under the slab?

The inspection determines how deep it goes; we scope the treatment to the real extent of contamination.

How much does it cost?

It depends on severity, area, and the prep needed. You get a documented, itemized estimate after the inspection — no guessing.

Do I need an inspection first?

Yes — it tells us how far the urine penetrated so the plan matches the real scope, not just what's visible.
