Services / Professional Pressure Washing

Pressure Washing

Pressure washing is one of the most effective and proven methods used in the wood restoration process. It not only cleans and prepares the wood surface, but also opens the wood pores, which helps maximize penetration and absorption of the stain or preservative. This is essential for achieving a longer-lasting finish and maximizing the longest service life possible.

When necessary, we utilize professional-grade wood cleaners and brighteners to remove dirt, mold, mildew, algae, fungus, and other stubborn residues. These specialized products restore the wood's natural appearance and rebalance the wood's pH, creating optimal conditions for staining.

The number one concern with pressure washing it that it can lead to log rot by forcing water deep into the wood. While not impossible, our experience has disproved this misconception over the last 3 decades in the arid and dry climates of the Mountain West.  More importantly, every project is carefully evaluated to determine the best cleaning and preparation methods based on the condition of the wood as well it's corresponding climate. While pressure washing is an extremely effective restoration tool, it is just one of several techniques we use to achieve the best possible results.

Every log home is different, which is why our process is tailored to condition, age, and previous treatment methods.

Frequently Asked Questions

How often should exterior wood be cleaned?

This step in the wood restoration process depends on a number of variables. These include altitude, directional aspect, exposure, the condition of the stain or finish, as well as the overall condition of the wood. A good rule of thumb is to have your home or wood structure analyzed by a professional every 4-7 years depending on the above factors.

Is pressure washing safe for wood?

The answer to this questions depends heavily on the current state of the wood. If wood rot isn't prevalent, then it most certianly is safe. Over the last three decades we've determined that moisture from pressure washing usually evaporates within 48-72. This also depends entirely on factors such as weather, temperature, humidity, etc. We always use a moisture meter to check the wood surface to ensure it's within proper range before applying the stain or preservative.

What PSI is appropriate?

We typically recommend at least 3,000 PSI to properly clean the wood surface and open the pores of the wood. We typically operate in a range of 3,000-4,400 PSI depending on variables like project size, wood type, the previous finish, as well as overall surface build-up. An important thing to note is that PSI is of secondary importance to the skill level of the technician operating the machine. * Cleaning exterior wood surfaces in this PSI range carries significant risk, and should only be done by a trained professional to avoid damage or injury.

How long does exterior wood cleaning take?

This depends entirely on project size, square footage, water pressure, water quantity, the type of stain or finish that was used previously, and whether or not you're attempting to remove the old finish. Additionally the process duration depends largely on the skill level of the individual performing the work.

Do i need to clean the wood surface before staining?

Yes, professional standards always recommend proper cleaning and preparation methods before applying the stain or preservative. This will ensure proper penetration and absorption while providing a longer service life. This is a crucial step that can end up saving the home-owner or contractor significant time and money.
