Residential Power Washing in Southbridge, MA

River Valley Moisture and Your Siding

Southbridge sits in the valley of the Quinebaug River, and that low ground holds moisture. Morning fog, humid summer air and shade from hillsides or neighboring buildings keep exterior surfaces damp for long stretches. That is exactly what green algae and black mildew need to thrive. On many Southbridge homes, the growth first shows up on north-facing walls, porch ceilings and the underside of soffits, then gradually creeps across the rest of the siding.

Multi-family homes and triple-deckers face the same issue on a larger scale, with tall walls and stacked porches that rarely see direct sun. Concrete steps, walkways and driveways add another layer, collecting winter sand and salt and turning dark under trees.

Walking Through a Southbridge Wash

Every job begins with a slow lap around the house. The tech closes any cracked windows, tapes over exterior outlets, notes where hose bibs are and gives flower beds a thorough drink of plain water so they are less likely to absorb runoff. Bikes, grills and porch chairs are moved out of the spray zone.

For the walls themselves, we rely on soft washing. A mild detergent mix is misted onto the clapboards or vinyl, allowed to dwell long enough to break the grip of the mildew, and then flushed off working downward from the eaves. Porch ceilings on older two- and three-story homes, which are often the dingiest surface on the whole building, get the same low-pressure treatment so paint is not peeled away in sheets.

Masonry and concrete are another matter. Here the machine is turned up so it can strip sanding grit out of the pores of a driveway, brighten brick steps and lift dark stains from under the maple out front. Wooden decks sit between the two extremes; a fan tip held at a consistent distance freshens the boards without carving lines across them.

• Low-pressure cleaning for walls and porch ceilings
• Heavier pressure on concrete, brick and stone
• Even, moderate passes across wooden decks
• Garden beds watered before and after

When Pressure Washing Near Southbridge Makes Sense

The sweet spot is the stretch between the last hard frost and the Fourth of July. Water will not freeze on the siding, the winter mess is plainly visible, and you get a clean house for the whole outdoor season. A September appointment is a good backup, particularly if you want the deck clean before sealing it. Once November arrives, things dry too slowly for us to recommend it.

Following Up With the Glass

Overspray inevitably dots the windows, which is why a lot of owners line up residential window cleaning for right after the wash.
