Garage Floor & Concrete Cleaning That Lifts Years of Oil and Grime in Northern Virginia
Garage floors take the worst abuse on your property — oil, road salt, tire rubber, and spills that never get rinsed. Our hot-water degrease and surface clean brings concrete back to a floor you are not embarrassed to open the door on.
The Short Answer
Most Northern Virginia garage floor cleanings run $150–$350 for a two-car garage, driven by oil staining and buildup. Hot-water degreasing lifts what rental machines leave behind, road salt and tire marks come up with the slab wash, and we squeegee-dry so the garage is usable the same day. Free walkthrough, written line-item quote within 24–48 hours.
The smartest combo is garage plus driveway — one setup, both concrete surfaces, one bundled price. And if an epoxy or sealer project is on your list, cleaning first is not optional: coatings bond to clean, pH-neutral concrete or they fail.
What's Included
Every Job, Done the Right Way
Our garage & concrete cleaning service covers everything the job actually needs — matched to your surfaces, never one-size-fits-all.
- Hot-water degrease — the full slab, not just the stains.
- Oil-spot extraction — targeted passes on soaked-in stains.
- Road-salt flush — winter chlorides rinsed before they spall the surface.
- Tire-mark removal — rubber transfer lifted from parking lanes.
- Walls splash-guarded — contents and finished walls protected.
- Contents workaround — we shift and swap bays when you can't empty fully.
- Squeegee dry — park again within hours, not days.
- Coating-prep option — pH-neutral finish ready for epoxy when requested.
Timeline: most garages finish in 2–3 hours and are parkable the same day. Best season: spring, flushing winter road salt before summer heat sets it.
Garage, Shop & Basement Concrete
Garage slabs get the full treatment: hot-water degreasing across the whole floor, extraction passes on soaked oil stains, and a chloride flush that clears the winter's road salt before it spalls the surface. Shop floors, sheds, and walk-out basement slabs are quoted the same way wherever drainage allows.
What drives your price: bay count, stain severity (fresh spills lift easily; years-old soaked stains take extraction and may leave a light shadow — we tell you which yours is up front), contents handling, and whether you're prepping for an epoxy coating, which demands a squeaky-clean pH-neutral slab. Most garages finish in 2–3 hours.

Local Knowledge
What Northern Virginia Garage Floors Actually Deal With
- Road salt brine soaks in all winterEvery snowy commute drips chloride brine onto the slab, where it wicks into the concrete and spalls the surface over the following summers.
- Oil stains set deeper every monthFresh drips lift almost completely; the same stain a year later has soaked past what any surface cleaning fully reverses.
- Humidity feeds musty filmsNoVA summers grow a grimy film on cool slab corners and behind storage — part of why garages smell the way they do.
- Clay dust settles everywhereYard work and open doors coat the slab in the region's red dust, which grinds into the surface under tires.
- Coatings fail from bad prepEpoxy and sealer failures almost always trace back to grease or pH left in the slab — professional cleaning is the foundation of any coating.
- Spring is the reset windowA post-winter flush clears salt at the moment it matters most — before summer heat drives it deeper.

Questions
Garage & Concrete Cleaning — Common Questions
How much does garage floor cleaning cost in Northern Virginia?
A typical two-car garage runs $150–$350 depending on staining. Adding the driveway while equipment is on site is the most cost-effective combo — quotes are written and line-item. Three-car garages and oversized bays scale up modestly — the setup cost is already paid once equipment is inside.
Can old oil stains really come out of concrete?
Most improve dramatically with hot water and professional degreasers; stains that soaked for years may leave a light shadow. We tell you which yours is at the walkthrough — before you spend a dollar. The honest forecast matters because expectations set the outcome: a 90% improvement on a decade-old stain is a win we’d rather promise accurately.
Do I need to empty my garage first?
Ideal but not required — we routinely shift contents to one bay, clean, and swap. Fully empty garages get the fastest, cheapest, most complete result. We stage contents on protective sheeting, so boxes and shelving come through the shuffle clean.
Should I clean concrete before epoxy coating?
Absolutely — coatings fail from bad prep, not bad paint. Our cleaning leaves the slab degreased and pH-neutral, exactly what coating manufacturers require for adhesion. If a coating contractor is already scheduled, we coordinate timing so the slab cures dry inside their prep window.
Does road salt actually damage garage floors?
Yes — salt brine tracked in all winter wicks into concrete and spalls the surface over time. An annual spring cleaning flushes chlorides out before they do structural damage. The spring flush also lifts the fine grit that grinds the surface under tires all summer.
How long until I can park in the garage again?
Same day — we squeegee-dry the slab and most floors are drive-ready within a few hours. Floor drains get flushed where present, which is often where the musty smell actually lives.
Do you also clean basement or shop concrete?
Yes, where drainage allows — shop floors, sheds, and walk-out basement slabs are quoted the same way as garages. Shop and basement slabs quote after a quick drainage check — most walk-outs qualify without any special setup.
