What Pressure Washing Services Usually Include

Pressure washing companies in South Carolina typically offer cleaning for driveways and concrete surfaces, which are among the most common requests. Siding cleaning—whether vinyl, brick, or wood—is another standard service, as is deck and patio cleaning. Some contractors also handle roof cleaning, fence washing, and gutter cleaning, though not all offer every service.

The equipment and water pressure used matter significantly. Too much pressure can strip paint, damage wood, or crack certain surfaces. Experienced contractors know which pressure settings work for different materials and adjust their approach accordingly. When you contact a pressure washing company, asking about their experience with your specific surface type—whether it's composite decking, vinyl siding, or sealed concrete—tells you whether they understand the risks.

How to Evaluate a Pressure Washing Company

Before hiring any pressure washing contractor, including Dewar, ask about their insurance and whether they carry liability coverage. This protects you if equipment damage or injury occurs on your property. You can also ask whether they have references from recent jobs similar to yours—a contractor who has cleaned dozens of driveways can speak to what results look like and how long they last.

Get a clear estimate in writing that specifies what surfaces will be cleaned, what pressure settings they plan to use, and whether they'll treat the area with any sealant or protective coating afterward. Some contractors include post-cleaning sealing as part of the service; others charge separately or don't offer it. Knowing this upfront prevents surprises when the invoice arrives.

Pressure Washing in South Carolina's Climate

South Carolina's humid subtropical climate means exterior surfaces accumulate mold, mildew, and algae faster than in drier regions. Driveways and patios often develop dark streaks within a year or two of pressure washing, especially in areas with shade or poor drainage. This is normal and doesn't mean the initial cleaning failed—it means the conditions that created the staining are still present.

Seasonal timing affects pressure washing results. Spring and early summer are popular times because surfaces are visibly dirty after winter, and the weather is mild enough for the work. However, scheduling in fall can be practical too, since you're preparing surfaces for winter and the air is still warm enough for any sealants to cure properly. Ask the contractor whether they recommend a particular season for your specific job.

Cost Factors for Pressure Washing Services

Pressure washing costs vary based on the size of the area, the type of surface, how heavily soiled it is, and your location within South Carolina. A small residential driveway costs less than a large commercial parking lot or a multi-story building exterior. Heavily stained or moldy surfaces may require additional treatments or multiple passes, which increases the price.

Getting quotes from at least two or three contractors in your area gives you a sense of the local market rate. If one quote is significantly lower than others, ask what's included—they may be offering a basic wash without sealant, or they may be newer and building their client base. If one is significantly higher, ask what additional services or guarantees justify the premium price.

Questions to Ask Before Hiring

When you contact Dewar Exterior Services or any pressure washing company, ask whether they're licensed and insured, what surfaces they have experience cleaning, and whether they offer any warranty or may provide on their work. Find out how long results typically last and whether they recommend follow-up treatments or maintenance.

Ask about their cancellation policy in case weather prevents the work, and confirm the timeline—whether they can start within a week or if there's a longer wait. Understanding these details before you commit helps you make a decision that fits your needs and timeline.

Will pressure washing damage my deck or siding?

Pressure washing can damage wood, composite, or vinyl if the pressure is too high or the technique is wrong. A contractor experienced with your specific material knows the safe pressure range. Always ask about their experience before hiring, and get a clear explanation of how they'll protect your surfaces.

How often should I have my driveway pressure washed?

This depends on your climate, shade, and drainage. In South Carolina's humid environment, many homeowners pressure wash every one to two years to keep mold and algae from building up. Some areas need it more often; others less. A contractor can recommend a schedule based on what they see.

What's the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water for tough stains on concrete and hard surfaces. Soft washing uses lower pressure and often includes cleaning solutions, making it safer for delicate surfaces like siding or roofs. Ask which method the contractor recommends for your job.

Should I get my roof pressure washed?

Roof pressure washing is risky—high pressure can damage shingles, and the work requires safety equipment and training. Many contractors recommend soft washing or chemical treatments for roofs instead. Ask whether the contractor has experience with roofs and what method they use before deciding.
