Like other pressure washing contractors in the state, they use high-pressure water systems to clean surfaces that standard methods cannot reach effectively.

Before hiring any pressure washing contractor, you should understand what the service involves, what it costs, and what questions to ask. This guide walks through how to evaluate A-Z Pressure Washing & Services alongside other local options, what to expect from the work, and how to protect your property during the process.

What pressure washing contractors actually do

Pressure washing uses a motorized pump to force water at high pressure—typically 1,500 to 4,000 pounds per square inch—onto outdoor surfaces. The force dislodges dirt, mold, algae, and weathered paint. Contractors may also use cleaning solutions designed for specific surfaces: deck cleaners, mold removers, or degreasers for driveways. Some contractors apply sealants after washing to protect wood or concrete from future staining.

The work is faster than hand-scrubbing but requires skill to avoid damage. Soft surfaces like wood siding or asphalt shingles can be gouged or stripped by excessive pressure. Concrete and brick are more forgiving. A contractor should adjust pressure based on the material being cleaned and know which surfaces need lower pressure or chemical treatment instead of force alone.

Common surfaces pressure washing handles

Driveways and concrete patios are the most common jobs. Pressure washing removes oil stains, algae, and dirt that accumulate over years. Decks—whether wood or composite—benefit from cleaning to remove mold and algae that make them slippery and cause rot. Wood decks need lower pressure and sometimes chemical treatment to avoid splintering.

Siding, whether vinyl, brick, or fiber cement, can be pressure washed to restore appearance, though vinyl requires careful pressure control. Roof cleaning is also offered by some contractors, though it is more specialized and carries higher risk. Fences, pool decks, and parking lots are other common applications. Before hiring, confirm that the contractor has experience with your specific surface type.

Questions to ask before hiring

Request references from recent jobs—ideally from properties similar to yours. Ask whether the contractor carries liability insurance and workers' compensation if employees will be on your property. A contractor without insurance shifts risk to you if someone is injured or property is damaged.

Ask what pressure settings they use for your surface type and whether they apply sealant afterward. Clarify whether the estimate includes moving outdoor furniture, protecting plants, or shutting off exterior outlets. Ask about their water source: some contractors use recycled water or have environmental practices that matter if you care about water conservation. Get the estimate in writing, specifying which surfaces will be cleaned and what the total cost is.

Pricing and what affects the cost

Pressure washing costs vary widely based on property size, how dirty the surfaces are, and what materials need cleaning. A small driveway might cost less than a large deck or full-house siding cleaning. Heavily soiled surfaces or those requiring chemical treatment cost more than light cleaning. Some contractors charge by the square foot; others quote per job.

Comparing three to five quotes from different contractors is normal practice and helps you understand the local market. The lowest price is not always the best value—a contractor using inadequate pressure or skipping preparation steps may leave you with poor results or damage. Mid-range pricing from an insured, experienced contractor is usually the safer choice.

Protecting your property during the work

Before the contractor arrives, move outdoor furniture, potted plants, and decorations away from the work area. Close windows and doors. If you have delicate plants near the cleaning area, ask the contractor how they will protect them—some use tarps or adjust their spray pattern. Shut off exterior electrical outlets or cover them if they are in the spray zone.

Stay home during the work if possible, or at least check in partway through. Watch for signs of damage—excessive water pressure stripping paint, or spray reaching windows or siding seams. If something looks wrong, stop the work and discuss it with the contractor before they continue.

After the cleaning is done

Once pressure washing is complete, inspect the work in daylight. Surfaces should look noticeably cleaner, with dirt and algae removed. If sealant was applied, ask the contractor how long it takes to cure and whether you should avoid the area for a period. Some sealants need 24 to 48 hours before rain or foot traffic.

If you notice damage—gouges in wood, stripped paint, or water intrusion into siding seams—document it with photos and contact the contractor immediately. Reputable contractors stand behind their work and will address problems. Keep the contractor's contact information and any warranty or may provide they provided in writing.

Frequently Asked Questions

Is pressure washing safe for all outdoor surfaces?

No. High pressure can damage wood siding, asphalt shingles, and some composite materials. Concrete and brick are more durable. A skilled contractor adjusts pressure based on the surface and may use chemical cleaning instead of force for delicate materials. Always confirm the contractor has experience with your specific surface before hiring.

How often should I have my driveway or deck pressure washed?

It depends on your climate and how much shade the surface gets. In humid areas like South Carolina, mold and algae return faster—many homeowners wash driveways and decks annually or every other year. Shaded areas need more frequent cleaning than sunny spots. Your contractor can recommend a schedule based on your property's conditions.

What is the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water to force dirt away. Soft washing uses lower pressure combined with chemical cleaners, taking longer but causing less risk of damage. Soft washing is better for delicate surfaces like wood or vinyl siding. Ask your contractor which method they recommend for your surfaces.

Do I need to be home while the work is happening?

You do not have to be, but it is a good idea to check in partway through. Being present lets you catch problems early and answer questions about where to direct the spray or what to protect. At minimum, make sure the contractor knows how to access water and where to park equipment.

Will pressure washing remove all mold and algae permanently?

Pressure washing removes visible mold and algae, but spores remain in the environment and can return, especially in shaded or damp areas. Applying a sealant or mold-inhibiting treatment after washing slows regrowth. In very humid climates, you may need cleaning again within a year or two, depending on the surface and location.
