Driveway and concrete cleaning

Start here

Is this the right service?

Routine cleaning suits sound flatwork with surface soil, tire marks, and organic growth. Deep oil migration, rust reactions, fertilizer burns, efflorescence, spalling, and failed sealer are different problems and may remain visible.

New, weak, decorative, colored, stamped, polished, or previously sealed concrete deserves a test and often a specialist method. Cleaning will not level a slab, repair cracks, or restore cement paste already removed.

Scope the method

Methods worth discussing

• Dry debris removal followed by stain-specific pretreatment
• A correctly sized surface cleaner for even passes on sound flatwork
• Controlled wand work at edges, joints, steps, and tight areas without cutting lines
• Hot water or degreaser for compatible oily soils, with an appropriate wastewater plan
• Post-treatment only when its purpose, compatibility, dwell time, and final rinse are clear

What a considered job looks like

From inspection to handover

1. Inspect and classify

   Map slab age, finish, cracks, repairs, sealer, drainage, stains, adjacent materials, and low points. Test uncertain surfaces.

2. Remove dry material

   Sweep or collect leaves, grit, loose aggregate, and litter so they are not pushed into drains or landscaping.

3. Treat specific stains

   Apply only the product and dwell time suited to oil, rust, minerals, organics, or tire residue; do not assume water pressure is the treatment.

4. Clean evenly

   Use consistent overlap, pace, distance, and edge technique. Manage runoff continuously rather than at the end.

5. Rinse, recover, and review

   Clear residues from joints and edges, leave water a safe destination, and inspect again as the slab dries.

Set expectations

What different marks may require

Risks to resolve before work starts

• Excess pressure or a zero-degree tip can expose aggregate, remove weak paste, and leave permanent lines
• Uneven passes can produce stripes visible only after drying
• Chemistry can discolor concrete, damage adjacent metal or stone, and affect lawns
• Runoff can carry sediment, oil, detergent, or treatment residue toward storm drains and neighboring property
• Freshly cleaned concrete is slippery and pooled water can refreeze in cold conditions

Compare the same job

What a useful written quote includes

• Measured area and each included surface, step, curb, wall, and edge
• Concrete age, finish, color, sealer or coating, repairs, cracks, and known weak spots
• A stain map separating oil, rust, minerals, organics, paint, tire marks, and unknown deposits
• Pretreatments, agitation, heat, post-treatment, test areas, and number of passes included
• Water source, drainage route, recovery requirements, adjacent protection, and cold-weather plan
• Expected result for each major stain plus the price of optional repeat treatment or sealing

Common exclusions to make explicit

• Guaranteed removal of deep oil, rust, battery, fertilizer, or mineral staining
• Crack repair, grinding, resurfacing, joint replacement, leveling, sealing, and coating removal unless itemized
• Moving heavy vehicles, storage, fixed planters, or equipment
• Wastewater capture, transport, testing, or disposal unless the quote assigns it

Before appointment day

How to prepare

• Move vehicles before arrival and prevent traffic until the agreed reopening time
• Remove small furnishings and sweep up personal items, pet waste, and loose debris
• Mark irrigation heads, low-voltage lights, loose joints, damaged edges, and known repairs
• Keep doors and windows closed and identify areas where water must not enter
• Confirm who will protect garage contents, walls, landscaping, drains, and neighboring surfaces

Do not inspect only while wet

Completion and aftercare

Walk the job before sign-off

• Inspect for evenness, circular marks, wand lines, edge cuts, loosened joints, and missed corners after partial drying
• Compare each named stain with its realistic agreed outcome
• Confirm sediment and debris were collected rather than left in beds, gutters, or drains
• Check garage doors, walls, steps, metal, landscaping, and adjacent finishes for splash or treatment residue
• Confirm the surface is safe for pedestrians and the reopening time is understood

After the crew leaves

• Let the slab dry evenly before assessing color; wet concrete hides shadows and striping
• Avoid vehicles, furniture, coatings, or sealer until the provider or product specification permits
• Address oil leaks, irrigation overspray, blocked drainage, and metal runoff that cause repeat stains
• Expect joints and deep pores to dry more slowly than the slab face

Choose deliberately

Questions for each provider

1. What are the slab finish, sealer condition, and weak areas, and where will you test?
2. Which stains receive separate treatment and what improvement is realistic?
3. Is the price based on measured area, and are edges, steps, curbs, post-treatment, and cleanup included?
4. How will you prevent lines or exposed aggregate?
5. Where will wash water, oil residue, sediment, and chemicals go?
6. When can people, vehicles, sealer, or coatings return to the surface?

Warning signs

• A firm price given without asking about the surface, condition, access, water, or photographs
• A promise that maximum pressure will remove every mark, with no test area or damage discussion
• No clear plan for protecting people, plants, adjacent property, drains, and sensitive fixtures
• A quote that does not identify the surfaces included, likely result, exclusions, and who handles cleanup
• Cleaning begins on new, decorative, sealed, or visibly weak concrete without identifying the finish or testing
• Oil-bearing or chemically treated water is simply directed to the nearest storm drain
