House Washing in Pittsburgh: The Complete Guide to Exterior Home Cleaning
Your home's exterior takes a beating every year. Pittsburgh's humid summers, wet springs, and heavy pollen seasons leave siding, trim, and foundations coated in algae, mold, mildew, and environmental grime. Professional house washing removes all of it in a single visit — restoring your home's appearance, protecting its surfaces, and boosting curb appeal without the cost of repainting or replacing siding.
What Is House Washing?
House washing is a complete top-to-bottom exterior cleaning of your home — siding, trim, foundation, soffits, shutters, and all exterior surfaces. Unlike pressure washing, which focuses on hard surfaces like driveways and patios, house washing is specifically designed for the exterior of your home and uses techniques matched to each surface type.
Most house washing uses a soft wash approach for siding: low-pressure application of biodegradable cleaning solution that kills and removes algae, mold, mildew, and organic buildup without the risk of forcing water behind siding panels or stripping paint. For brick and concrete foundation walls, appropriate pressure is used to remove embedded dirt and staining.
Why Pittsburgh Homes Need Regular House Washing
Pittsburgh's climate creates ideal conditions for exterior buildup. The city's river valley location keeps humidity high through much of the year, and the region's heavy tree canopy means many homes have shaded north and west-facing walls that stay damp — perfect conditions for algae and mold to establish and spread.
Beyond the climate, Pittsburgh's air quality — while much improved from its industrial past — still deposits particulates on exterior surfaces. Combined with pollen, road dust, and organic matter from trees, siding can go from clean to visibly dirty within a single season.
The consequences of neglect go beyond aesthetics. Algae and mold retain moisture against siding, accelerating deterioration. On vinyl, this can cause chalking and color fade. On wood, it leads to rot. On painted surfaces, it causes peeling and blistering. Regular cleaning prevents these problems before they become expensive repairs.
What's Included in a Professional House Wash
A professional house washing service from SHS Exterior Cleaning includes the full exterior of your home: all siding surfaces, trim and fascia boards, soffits, shutters, foundation walls, and any attached structures like porches or covered entries. We clean from the roofline down to the foundation — not just the easy-to-reach sections.
We also protect your property during the process: windows and doors are protected from overspray, landscaping is pre-wet and rinsed, and we clean up any debris before we leave. The result is a uniformly clean exterior, not just the sections that were most visible from the street.
How Often Should You Wash Your House?
Most Pittsburgh homeowners benefit from a full house wash once a year. Spring is the most popular time — after pollen season ends and before summer heat sets in. Fall is also a good window, clearing summer's algae growth before winter.
Homes with heavy tree cover, north-facing walls, or visible mold and algae may benefit from washing twice a year. If you're preparing to sell, paint, or re-stain your home, a professional wash is an essential first step.
House Washing Costs in Pittsburgh
Professional house washing for an average Pittsburgh-area home typically runs $250–$500. Price depends on the size of your home (square footage of exterior surface), siding type, and the level of buildup. Homes with heavy mold or algae growth may require additional treatment time.
