siding contractor & rain drop moisture barrier in portland oregon & vancouver washington

March 26, 2010 by Superior Exterior Systems Experts Leave a reply »

You may have read my angry blog a few months ago on the new oregon MANDATED rain screen laws. We are happy to announce that will be carrying a simple yet affective solution. Although it technically isn’t law in southern washington, it can still be used there too.  A manufacturer named Green Guard has come up with a building envelope moisture barrier called RainDrop. It has vertical raised lines imbedded into the wrap that actually allow unwanted moisture to drain thru to the bottom and out. Again, remember the idea is to allow no water in the wall which always requires upkeep from the homeowner with caulking and painting so dont put that off.  This Rain Drop housewrap & moisture barrier we will be carrying is made of cross woven polyolefin designed with an enhanced contour to facilitate the drainage of water that may penetrate the siding in wind driven rain. It wont breakdown over time and is a practical concept which wont raise the siding cost at all. There are other methods that will raise the cost significantly . In my previous blog you could tell I was FURIOUS about this oregon new law but am now happy to say this is a practical & effective option and will not raise the cost where the other options are significantly more expensive.  With an expense like this most homeowners focus on the finish look and dont want to pay alot for the moisture barrier application which is eventually unseen so this is very cost effective and still delivers results but MUST be installed properly.  As a siding contractor in the portland metro and southern washington area we are always here to earn your trust while educating you offering numerous options so you can decide whats best for you instead of letting a high pressure salesman decide. This is another reason why we are so well known with local realtors and there problems with listing Lp homes. Visit us at for even more information and lots of pictures with design ideas that may help you. Or you can simply call us at (503)285-0875 or (360)687- 8936.  Thanks again for listening.
