Rotting siding on your Portland home?
We take it back to the sheathing, fix what the water got to, and put on siding that lasts. We have been doing exteriors in the Pacific Northwest since 2002.

What is going on with your siding?
Pick the closest one. Takes a second and it tells us what to look for.
If your siding has a few years left in it, we will tell you that instead of selling you a job.
Or just call (503) 914-0200
What we find when we open a wall
This is a real job, not a stock photo. Once the old siding comes off you can finally see the sheathing, and that is where the story is. Wet spots, black staining, soft plywood around the windows.
Some houses are clean back there and we tell you so. When they are not, we show you before anything gets covered back up, and you get a price for the repair before we do it. Nobody should find out about rot after the invoice.
Have us take a look
We side apartment buildings for a living
Most of our work is four and five story buildings for general contractors, where the inspection is real and a leak is somebody's lawsuit. Apartments, condos and commercial projects across Portland and Vancouver.
Your house gets those crews and that same wall detailing. Most siding companies have never had to build a wall to that standard.

Since 2002
Over 20 years of Pacific Northwest rain, on buildings that still have to pass inspection.
Vetted crews
The same trained crews and trade partners we use on commercial jobs, not whoever is available that week.
Water first
The barrier behind the siding is the part that matters.
How to tell your siding is done
Siding fails from the back first. By the time you can see it from the street, water has usually been getting behind it for a while.
Soft or spongy spots
Press on it. If it gives, water is already in the board.
Paint that will not hold
Repainting every few years usually means the substrate is soaking.
Cracked or split boards
Splits let water straight into the wall behind the siding.
Gaps at joints and trim
Old caulk lets go. That is the most common entry point we find.
Bubbling or warping
Board is swelling from moisture and will not go back flat.
Mold or dark streaks
Often a sign the wall behind is staying wet after it rains.
What we put on
James Hardie
Lap siding, shingle, and panel. Fiber cement does not rot or swell, and it is non combustible. This is what most Portland homes get.
Pre finished fiber cement
Nichiha and CeraClad come with the color already on from the factory, so there is no painting after the install.
Cedar and composite
Real wood or engineered composite when you want that look. We will tell you straight what the upkeep is.
How it goes
We come look
We walk the house with you, check the siding, and find where the water is getting in.
You get a written price
Materials, labor, and what is included. You pick the product and the color.
We do the work
Vetted crews. We show you anything we find behind the old siding before we cover it.

"I have worked with a number of other contractors and know when I'm working with someone who knows their business and takes genuine pride in the quality of the work they're doing, and that certainly describes Vito and the sub contractors he works with. Highly recommend Exteriors Design for any level of remodeling or renovation jobs you may be doing!"
