Residential Cleaning

Low pressure exterior steam cleaning
House washing


Dirt, stains, mildew and environmental debris build up on a home, gradually dulling and fading the exterior.  This leaves the finish tired-looking and lackluster.  Cleaning the exterior discourages the growth of mold and mildew, both of which can cause allergic reactions and respiratory problems as well as deterioration of the surfaces of they inhabit.  

Many homeowners consider pressure washing as the simple act of spraying (highly pressurized) water and liken it to a DIY project such as washing a car.  In most home exterior situations this is not the case.  More often, what is intended to be a small DIY job, turns into a day-long or weekend-long project requiring the timely and costly addition of supplies such as ladders, hoses, brushes, etc.  And long after the unintentionally costly and backbreaking work is over, the results simply will not compare to a professional.  All too often the homeowner is left with a lackluster finished appearance and sometimes, more difficult problems to contend with on the siding.

Numerous techniques are required for properly cleaning home exteriors and/or preparing for painting.  There are many causes for the staining that occurs and not all power washing contractors practice the same methods of cleaning.  As with other trades, homeowners and consumers should be selective when choosing providers to avoid service issues that result from improper washing procedures and/or inexperience. 


Homeowners should be aware that not all power washers are alike or even similar. Just as owning a camera does not make up the professional photographer and owning a wrench does not make the mechanic,owning a power washer does not make a power washing or softwashing professional. The term softwashing, in a nutshell, is just that. It means soft washing. Unfortunately, the term is now being referred to (whether mistakenly or unscrupulously) by some copycat but web savvy high pressure washing companies.  Softwashing DOES NOT and SHOULD NOT utilize or ever require anything more than 500 psi to clean the surface.  At GSPW, we most often clean with as little as 40psi for incredibly safe, efficient cleaning yet truly unbeatable results.   

Granite State Pressure Washing offers an unbeatable level of quality and professionalism in home exterior cleaning with our exclusive low pressure soft washing approach to cleaning home exteriors.  In most circumstances, high pressure should NEVER be utilized in cleaning home exteriors.  Don’t be fooled by the downward angle marketing approach of inappropriate high pressure washing as this can damage the home’s siding just as easily as any upward angle high pressure washing approach.

Granite State Pressure Washing utilizes a very low pressure, steam cleaning approach that not only outperforms high pressure washing but is also the safest home exterior cleaning method, virtually eliminating the need for the standard harsh chemicals regularly used in high pressure washing.  Just as a dishwasher uses hot water to achieve maximum cleaning results, cleaning the home exterior works in the same manner.  However, it is the combination of stain cause and solution knowledge, water temperature, appropriate cleaning products, proper water pressure and cleaning method together that makes an incredible difference in the level of clean that can be safely be achieved with home exterior surfaces.

We are the power washing professionals, the other pros call for help.  Of course, this usually happens after first imitating our marketing or advertisements (except with stock photography and misrepresentation) and then offering a remarkably LOW, LOW price.  On too many occasions, these competitors inadvertently damage a surface they are simply unprepared and unable to clean correctly…usually because of LOW, LOW prices and a lack of knowledge and ability to perform the service the right way.   Over the years many power washing contractors have come and gone in NH, however Granite State Pressure Washing continues to offer professional house washing, deck and fence cleaning, sidewalk cleaning and roof cleaning with an unbeatable level of service at a fair price.  We care about our customers and our employees and remain committed to upholding our reputation as industry leaders while offering a new and necessary level of professionalism in the industry.


When the exterior needs repainting, Granite State Pressure Washing will prepare the surface correctly for repainting.  Professional pressure washing is by itself its own trade and should be performed by full time power washing professionals who will carry the correct equipment and utilize the most appropriate cleaning and preparation methods.  Painting over unseen mildew is a common cause of paint discoloration and using inappropriate high pressure where it can damage the exterior negates the value of any paint job.  Granite State Pressure Washing is the chosen provider of paint preparation pressure washing by professional painters in the southern NH area.
