Portland, Oregon, gets an average of 43 inches of rain per year. Could you imagine if a window or the siding on the exterior of your house was damaged? It may cause a leak, letting all that rainwater into your home and damaging structure along the way. Sometimes leaking windows are difficult to spot early on, as the signs aren’t always as apparent as a drip or a puddle. Other times they could be subtle, like a water stain on sills, jambs, and the drywall surrounding the window. Other signs could include mold, musty odors, rotten or swollen trim, or dark streaking behind the window. With the wet climate we have here in the Pacific Northwest, all sorts of problems could occur.
