Serving Portola Valley Since 2010

Pacific Exterior is Northern California's original non-pressure cleaning and restoration specialist. Our decades of experience as a general building contractor give us the knowledge and insight to provide the best solutions for all of our client's needs.

We are an NRCIA-certified roof inspector and building contractor that has applied and installed all of the materials and products that we now specialize in cleaning and restoring.

We have been featured multiple times in international trade magazines, most recently, one of the nations leading decorative concrete trade magazines featured our article on 'Modern Hard Surface Cleaning and Restoration’. In January 2014 eClean magazine featured our discovery of bacterial growth patterns on building surfaces.

The article, titled Bacterial Stud Striping, to this day remains the only reliable piece of information on the subject of bacterial growth patterns on building exteriors.

The result of our research has led us to adopt our "Safe Wash" cleaning technique and recommend it to other cleaning professionals throughout the country. Today, we clean and restore some of the most beautiful homes and iconic commercial buildings in Northern California.

We encourage you to view our extensive portfolio to see the results of our non-pressure cleaning processes for residential and commercial properties in and around the Bay Area.

We are proud to serve all of Portola Valley and the unique residential neighborhoods of Palo Alto, Redwood City, Stanford, Atherton, Hillsborough, Woodside, and Menlo Park.

Frequently Asked Questions

Yes. Cleaning your roof can save you money in more ways than one...

  • First, the algae and fungus that grow can cause premature roof granule loss, and shorten roof shingle life. So you save money because your roof lasts longer
  • Second, when the algae turn your roof black, it becomes less reflective, and it retains heat; If you use an air conditioner it has to work harder to overcome the increased heat load, costing money in electric bills.
  • Third, the aesthetics of cleaning your roof when it comes to selling your home can not only save you money but can make you money too.

It would be appreciated if you could do a few things the night before we come out to do the roof cleaning service:

  • Move all lawn equipment, furniture, and/or toys inside or away from the building.
  • Keep all animals inside or out away from the home.
  • Put any special plants out away from the house (if possible.)
  • Park vehicles on street or in the garage.

Pretty much just clear everything out away from around the house. We will be rinsing areas around the building during the treatment.

We almost exclusively use equipment no louder than a whisper. Occasionally we use a compressor for large commercial projects.
