Pressure Washing

Pressure Washing

Generally speaking, pressure washing is the quickest and least expensive choice.

Pressure washing (also referred to power washing) is the function of using highly pressurized water to remove mildew, mold, dirt, pollen, UV graying, etc. You’ll hear different recommendations whether or not pressure washing your logs is the best cleaning method.

One fallacy is that you’re saturating and “damaging” your logs with water as a result of pressure washing. This simply isn’t true. On hard, sound, rot-free logs, you’re only introducing water into the top fibers of the wood.

The time it takes to pressure wash and the results generated are often directly associated with the type of finish being removed as well as how many coats have been applied. While some older, obsolete linseed based oil stains are more difficult to remove than newer products, practically everything can be removed with proper pressure washing techniques and good finish removers. Some of these older type products will often need S-100 or StripIt stripper applied first in order to soften the bond to the wood.

Traditionally, newer, recently peeled logs have a greater surface hardness and can withstand highly aggressive pressure washing (if needed) easier than a log wall which has been fully exposed to direct sun for 20 years. You might notice your upper and lower fascia boards have aged and darkened at an accelerated rate compared to your logs. Because these areas are often made from softer (i.e. pine) wood, they are more likely to absorb water leading to more prominent mildew growth. These areas can easily resemble new wood once cleaned.

Pressure washing of new constructions can also easily remove the UV graying of the logs that can start occurring just weeks after the logs are stacked, particularly if exposed to direct sunlight.


In addition to log and wood sided structures, other areas where pressure washing can be utilized include driveways, stone walkways, pool decking, stone walls, fencing, gutters, downspouts, roofing and other areas. Concrete slowly builds up a browning/green appearance over time which usually consists of grease, dirt, mildew and algae which can easily be cleaned.

Pressure washing can be done in practically any temperature and weather conditions, although chemical strippers, which are often applied prior to cleaning, work much better in warmer weather.
