Power Washing Services That Restore Surfaces

Not when done correctly. The risk of damage comes from using too much pressure on the wrong surface — a common problem with DIY or inexperienced operators. Our crews calibrate PSI, select the appropriate nozzle tip, and maintain proper standoff distance for each material. Concrete and brick can handle 2,500–3,000 PSI. Pavers get 1,200–1,800 PSI. Wood surfaces stay under 1,500 PSI with a wide fan tip. We never power wash vinyl siding, painted wood, or roofing — those get soft washed instead.

For most residential properties in Southeastern Massachusetts, we recommend annual power washing for driveways, walkways, and patios — typically in spring to clear winter salt, sand, and the organic growth that thrives in our humid climate. Shaded areas prone to moss and algae may benefit from twice-yearly cleaning. Commercial properties with heavy foot traffic often need quarterly or bi-annual service. If you're planning an exterior painting project, power washing should happen 1–2 weeks before painting begins.

Pricing depends on the total square footage, surface type, stain severity, and accessibility. A typical residential driveway runs $150–$300. A full property wash (driveway, walkways, patio, and building exterior) ranges from $400–$800 depending on size. Commercial projects are quoted individually based on scope. We provide free, no-obligation estimates after a brief property walkthrough — you'll know the exact cost before we start.

Yes, power washing can remove loose, flaking, and peeling paint — which is exactly why it's a standard step in our exterior painting prep process. However, it won't strip firmly adhered paint from a surface, nor should it. The goal of pre-paint power washing is to remove everything that's failing so the new paint bonds to a solid substrate. If you need full paint stripping, that requires additional methods like scraping and sanding, which our painting crews handle as part of a complete exterior repaint.

Spring (April through June) is the most popular season for power washing in our area. Winter leaves behind road salt, sand, and debris on driveways and walkways, while the humid spring air kicks algae and mildew growth into high gear. A spring power wash clears all of that and gets your property looking sharp for summer. Fall is a smart second option — cleaning before winter prevents organic material from freezing into surfaces and causing staining or deterioration over the cold months.

Yes, pavers and natural stone are ideal candidates for power washing. We reduce the PSI to 1,200–1,800 and use a wide fan tip to clean evenly without dislodging joint sand or chipping stone edges. After washing, we can re-sand polymeric joints if needed so your patio looks and functions like new. Many homeowners are amazed at the color difference once years of embedded dirt, moss, and algae are removed.

We take plant protection seriously on every residential job. Before starting, we cover adjacent flower beds and shrubs with tarps and pre-soak landscaping with clean water so roots absorb moisture before any detergent runoff reaches them. Our cleaning solutions are biodegradable and break down quickly. After washing, we rinse all surrounding areas with clean water. In 65+ years of exterior work, protecting our customers' landscaping has always been part of the job.

No, you don't need to be home as long as we have access to the areas being cleaned and an outdoor water spigot. We'll coordinate any specific instructions beforehand — like keeping pets inside or noting areas to avoid. After the job, we photograph the results and send them to you along with any maintenance recommendations. If you prefer to be present for the final walkthrough, we're happy to schedule accordingly.

We can absolutely clean your siding during the same visit, but siding gets soft washed — not power washed. High pressure can crack vinyl, force water behind clapboards, and damage painted surfaces. We bring both rigs to every residential job so we can power wash your hardscapes and soft wash your siding, trim, and gutters in a single appointment. Bundling services saves you money compared to scheduling them separately.

Yes, parking structures and lots are one of our most common commercial power washing services. We use industrial-grade surface cleaners and hot water when needed to remove oil stains, tire marks, and built-up grime from concrete floors and walls. For occupied garages, we work section by section so tenants always have access to parking. We also handle proper wastewater containment and disposal in compliance with local environmental regulations.

Yes, we offer quarterly, bi-annual, and annual maintenance contracts for commercial properties. Recurring contracts keep your building exterior, sidewalks, loading docks, and parking areas consistently clean — which matters for customer perception and tenant satisfaction. Contract clients receive priority scheduling and discounted per-visit pricing. We will assess your property and recommend a cleaning frequency based on foot traffic, exposure, and surface types.

Absolutely. We understand that power washing during business hours can disrupt your customers and operations. We offer flexible scheduling to minimize impact on your business. For restaurants, retail storefronts, and medical offices, we coordinate timing around your operating schedule so your business runs without interruption. Just let us know your preferred window and we will build the schedule around it.

Yes. Nelson Painting carries full commercial general liability insurance and workers' compensation coverage. We provide certificates of insurance (COI) to property managers, building owners, and general contractors upon request — typically within 24 hours. Our insurance meets the requirements of most commercial property management companies and HOA associations in Southeastern Massachusetts.
