Window Replacement in Portland – 3 Important Installation Techniques to Prevent Water Damage

Exactly why is getting your windows changed different in Portland Or than it is in Phoenix Arizona or Mis Angeles, or even Bend over Oregon? It all comes down to climate. Portland receives 40. 7 inches wide of rain annually. Mis Angeles gets merely a 14. 5 inches, Phoenix a whopping 7. 6 inches wide, and Bend Oregon gets only 11. 7 inches wide, even though it’s still in the same express as Portland. So Portland gets three to five times more rainfall than those other cities we compared. window replacement Pleasanton

The reason accurate window replacement is so critical in Portland is the fact due to high gross annual rainfall statistics, if done incorrectly, rain leaks into your home can cause major water harm and mold to your wood framing, insulation, drywall, paint, and flooring. And because of Portland’s rain fall and high average moisture, mold can also form in walls and cause many health issues for the home’s inhabitants. 

The regular cost to repair normal water damage in Portland is $5, 000 so getting your windows replaced appropriately in Portland is vital. If you’re doing your own window replacement or having it done by a local contractor, there are three main techniques which need to be used to ensure a leak-proof installation. Below, I will list these in their order worth addressing, not necessarily in chronological order.

1. Flashing above the window trim. The bulk of window installations require the installer to piece around the window in order to get rid of the old one. Most old house windows, especially the aluminum ones, have nailing flanges around the perimeter. In order to remove the old window and install a new one with flanges, a cut must be made around the edge of the window.

After the new window is installed, wood trim is put around it and caulked. But caulking alone near the top of the trim won’t keep water out. Metal boasting, called z metal, has to be properly installed in back of the siding and over the new trim. Several contractors in the Portland area don’t install this important piece of boasting. It takes more efforts to feed it at the rear of the siding. They just caulk it and get paid by the property owner, knowing that after their 12 months warrantee is over, it will probably learn to trickle. So z-metal flashing, is the number one approach I recommend to prevent water infiltration.

2. Closing the nailing flange to the wall sheeting or building paper. The second most important technique to implement during the windowpane replacement process is to properly seal the window’s nailing flange to the wall sheeting. How is this done, you ask? You will discover two products I actually recommend that are readily available in the Portland area. One is Tyvek record. This is a product made by Dupont and it works beautifully for sealing the flange.

Following your window is put in the rough opening, the installer should apply this tape around the home window perimeter making sure 50 percent the tape adheres to the new vinyl home window nailing flange and the other half adheres to the wall sheeting or sub-siding. This should performed only if it’s not raining (which is rarely in Portland) and the wall sheeting is dried. Apply tape to the bottom flange first, then the sides, and lastly the top flange. If your home has building newspaper above the wall sheeting, apply the tape to this paper.

3. Caulking amply. There are several times you need to apply caulking through the window substitute process. The first program is before you placed the window in the opening. Evenly apply silicon caulking around the edge of the window beginning where the nailing flange will lay over it.

Then put the new home window flange within the caulking while it’s still wet. Apply a second bead over the flange and Tyvek tape before you set up the wood trim about the new window. This should be silicone caulking, as well. The trim should be installed over the caulking while it’s damp.

The final caulking should be applied after the trim is installed. This kind of time use a good, exterior caulking that’s can be painted as likely paint the new trim and the siding next to it. Caulking should be used on the gap between the new trim and the siding. Use white caulking in the distance between the new home window and the new cut. Don’t scrimp on the quality of the last caulking used.

These 3 techniques, done correctly, will ensure your window substitute project to be leak free, even in a town like Portland Oregon where over 40 inches of rain falls every season.
