How much does house washing cost in Irmo?

Most single-family homes run somewhere between $200 and $500 for a full soft wash, depending on square footage, number of stories, and how much mildew or algae buildup there is. Two-story homes with heavy shade or lake-adjacent moisture tend to land at the higher end.

How often does a house need to be washed?

Once a year is typical for most Irmo homes, though shaded lots or homes backing up to trees and water may need it every 8 to 10 months to stay ahead of algae streaking, especially on the north and east sides that don't get much direct sun.

What should I expect on the day of service?

A crew should walk the property first, cover or move anything sensitive nearby, apply the cleaning solution and let it sit for several minutes to work on mold and mildew, then rinse at low pressure. Expect the whole job to take 1 to 3 hours for an average-sized house, with visible results the same day, though some staining fades further as things dry.

How can I judge the quality of the work afterward?

Check corners, under eaves, and behind downspouts where crews sometimes rush. Streaking that reappears within weeks usually means the solution wasn't given enough dwell time or the mix was too weak. Good work leaves siding uniform in color with no streaks, no residue in window tracks, and no dead grass or scorched plants along the foundation line.

House Washing in Irmo

What house washing covers

House washing is the exterior cleaning of siding, brick, stucco, trim, soffits, and gutters to remove mold, mildew, algae streaks, pollen film, and general grime buildup. In Irmo's humid summers and shaded lots near Lake Murray, algae and mildew show up fast on north-facing walls and anything under tree cover. Most jobs use a soft wash method: a low-pressure application of a cleaning solution (usually a diluted bleach or surfactant mix) that kills spores at the root, followed by a gentle rinse. This is different from blasting siding with a pressure washer wand, which can force water behind panels, strip paint, or crack vinyl if the operator isn't careful with pressure and distance.

What to look for before you hire

Soft wash equipment and know-how, not just a pressure washer turned down low. Vinyl, wood, and painted surfaces need different chemical ratios and dwell times.
Plant and landscaping protection: pre-wetting shrubs, rinsing beds after, and using cleaners that won't scorch grass.
Insurance in case a window seal, screen, or light fixture gets damaged.
Clear scope covering whether gutters, fascia, and driveway or walkway rinsing are included or billed separately.

Squeegee Clean Inc.

4.9(737)✓ Google-verified

Squeegee Clean earns consistent praise for professionalism, friendly technicians, and thorough work across multiple services. Their window cleaning with purified water stands out for clarity that lasts months, and staff like Chase, Malik, Ricky, and Aiden get named for their knowledge and politeness. One 2023 dispute over flood light damage reveals a weakness: the owner resisted accountability, blamed equipment failure on bulbs, and refused a $50 replacement despite damage reviewers linked directly to the wash crew. The business handles complex projects well, schedules punctually, and communicates transparently during the estimate phase. Multiple repeat customers and neighborhood HOA contracts back up the broad capability across house, window, deck, patio, gutter, and solar panel cleaning. Pricing comes across as fair, though budget-conscious customers weighing the damage claim should know the company has contested liability in the past.
