How to research a pressure washing contractor

Start by checking whether the contractor is registered with the South Carolina Secretary of State if they operate as a business entity. You can search business records online to confirm their registration status. Look for reviews on Google, Facebook, and the Better Business Bureau to see what past customers report about their work quality and professionalism.

Ask the contractor directly for references—ideally three to five customers from the past year whose work is similar to yours. Contact those references and ask whether the work was completed on time, whether the contractor cleaned up afterward, and whether they would hire them again. A contractor confident in their work will provide references readily.

Verify that the contractor carries liability insurance. This protects you if their equipment damages your property or if someone is injured during the work. Ask them to provide proof of insurance before they start any job. A contractor without insurance is a significant financial risk.

What to ask about equipment and methods

Pressure washers vary in power, measured in PSI (pounds per square inch). A driveway can handle 3000 to 4000 PSI, but wood siding or a roof requires much lower pressure—often 1500 PSI or less—to avoid damage. Ask what PSI the contractor uses for different surfaces and why. If they say they use the same pressure for everything, that is a red flag.

Ask whether they use hot water or cold water. Hot water cleaning is more effective for removing grease and oil but costs more. Cold water works well for general dirt and mold on most surfaces. The right choice depends on what you are cleaning and why.

Inquire about cleaning solutions. Some contractors use biodegradable, environmentally friendly detergents, while others use stronger chemicals. If you have pets, children, or plants near the area being cleaned, discuss what products they plan to use and whether they will rinse thoroughly afterward.

Getting a written estimate

Never hire a pressure washing contractor based on a phone quote alone. Ask them to visit your property and provide a written estimate. The estimate should list exactly what will be cleaned, the method they will use, the timeline for completion, and the total cost. It should also specify whether the price includes cleanup and disposal of debris.

Compare estimates from at least two contractors. A significantly lower price may indicate they are cutting corners—using excessive pressure, skipping proper rinsing, or using cheaper materials that could damage your property. A significantly higher price does not always mean better quality, but it may reflect more experience or higher insurance costs.

Ask whether the estimate is binding or if additional charges might apply if they discover damage or unexpected conditions during the work. Understand their payment terms—whether they require a deposit, when payment is due, and what happens if you are not satisfied with the work.

Understanding surface-specific concerns

Concrete driveways and patios are durable and can handle higher pressure, typically 3000 to 4000 PSI. However, if the concrete is old or already cracked, lower pressure may be safer. Pressure washing can expose underlying damage, so discuss this possibility before work begins.

Wood decks and siding require careful handling. Pressure that is too high can splinter wood, open grain, and create entry points for water and rot. Most wood surfaces need 1200 to 1500 PSI at most. Ask whether the contractor will use a fan-spray nozzle rather than a concentrated stream, and whether they will apply a sealant after cleaning to protect the wood.

Vinyl siding is also sensitive to high pressure. Excessive force can crack panels or force water behind the siding, causing mold inside walls. Vinyl typically needs 1300 to 1600 PSI. Brick and stone can handle moderate pressure but may be damaged by concentrated streams, especially if mortar is old or deteriorating.

What happens after the work is done

Before the contractor leaves, walk the property together and inspect the work. Look for areas that were missed, uneven cleaning, or damage to surfaces. If you notice problems, address them immediately while the contractor is still there. Get any agreed-upon corrections in writing.

Ask about follow-up care. Some surfaces benefit from sealing after pressure washing to protect against dirt and weather damage. The contractor may offer this as an additional service, or they may recommend you hire a separate contractor for sealing. Understand what maintenance will help your cleaned surfaces last longer.

Keep records of the work done, including photos, the contractor's invoice, and any warranty or may provide they offer. This documentation is useful if problems develop later or if you need to file an insurance claim.

Frequently Asked Questions

How do I know if a pressure washing contractor is insured?

Ask the contractor to provide a certificate of liability insurance before work begins. The certificate should show their business name, the insurance company, the policy number, and coverage limits. You can also contact the insurance company directly to verify the policy is active. Never hire a contractor who cannot provide proof of insurance.

Can pressure washing damage my property?

Yes, if done incorrectly. Excessive pressure can crack concrete, splinter wood, crack vinyl siding, and damage mortar in brick. This is why asking about PSI levels and surface-specific techniques matters. A may have access to contractor will adjust their method based on what they are cleaning.

What should I do if I am not satisfied with the work?

Contact the contractor immediately and describe the problem. Most reputable contractors will return to address issues at no extra cost. If they refuse, document the problem with photos and refer to your written estimate and any warranty they offered. Small claims court is an option if the damage is significant and the contractor will not make it right.

How often should I have my property pressure washed?

This depends on your climate, the surface, and how much dirt accumulates. Most homeowners pressure wash driveways and patios every one to two years. Siding may need cleaning every two to three years. In humid areas with more mold and mildew, more frequent cleaning may be necessary. Ask your contractor for a recommendation based on your specific property.

Is pressure washing better than other cleaning methods?

Pressure washing is effective for many surfaces but not all. Soft-washing—using lower pressure with specialized detergents—is better for delicate surfaces like wood and some types of siding. For heavily soiled concrete, pressure washing is usually the fastest option. The right method depends on what you are cleaning and the condition of the surface.
