Not every home costs the same to pressure wash, and size is the single biggest factor behind that variation. A small single-story home in Hauppauge typically costs $250–$350 to wash, while a large two- or three-story home can run $500–$600 or more, simply because there’s more surface area, height, and time involved.
Why Home Size Is the Biggest Pricing Factor
Pressure and soft washing are priced largely around labor time and product volume, both of which increase as square footage and height increase. A crew washing a 3,500-square-foot colonial will spend meaningfully more time on-site than one washing a 1,200-square-foot ranch, even before factoring in buildup severity.
Pressure Washing Cost by Home Size
Small homes (under 1,500 sq. ft.)
Smaller single-story homes, common in some of Hauppauge’s older neighborhoods, generally fall at the lower end of the range, often $250–$350 for a standard house wash.
Mid-size homes (1,500–2,500 sq. ft.)
Most Hauppauge homes fall into this range, and typically cost $350–$500, depending on siding material and buildup.
Large homes (2,500+ sq. ft. or multi-story)
Larger homes, especially two- and three-story properties, often run $500–$600 or more, particularly if the home also needs roof washing, which is priced separately.
How Number of Stories Changes the Price
Height adds complexity beyond just surface area. Second- and third-story exteriors require extended equipment reach and more careful technique to maintain even coverage and water pressure, which is why two similarly sized homes — one single-story, one two-story — can still see different quotes.
Other Size-Related Cost Factors
Additional structures (garages, sheds)
Detached garages, sheds, or fences are often quoted as add-ons rather than included in a base house-washing price, since they add separate surface area to clean.
Landscaping and obstacles
Dense landscaping, fencing close to the house, or multiple stories of windows can add time to a job regardless of the home’s overall square footage, since crews need to work carefully around obstacles.

Frequently Asked Questions
Q: Does a two-story home cost more to pressure wash than a one-story home? A: Yes. Two-story and three-story homes generally cost more because of the added time, equipment reach, and technique required to clean upper-level siding evenly.
Q: Is pressure washing priced per square foot? A: Many companies use square footage as a starting reference point, but the final price also depends on buildup severity, siding material, and roofline, so quotes are typically customized per home.
Q: Are detached garages or sheds included in a house-washing quote? A: Detached structures are usually quoted as separate add-ons since they add extra surface area beyond the main house.
