Why Vancouver & Portland Homes Need Quality Siding

Our region is uniquely brutal on siding. Constant wet-dry cycles, north-side moss and lichen, and horizontal rain driven by winter storms all attack siding — and even more importantly, the moisture that gets behind the siding. Homes built in the 1980s and 1990s often have T1-11 plywood siding, hardboard, or early-generation vinyl that's now failing. Original cedar shakes on older homes may be showing gaps, curl, or hidden rot.

Warning signs it's time to replace:

Soft spots or visible rot around windows, doors, or bottom courses
Peeling paint that returns every 2-3 years no matter what you do
Cracked, warped, or missing pieces
Moisture stains on interior walls
Hardboard or T1-11 that's swelling or delaminating
Original siding still on a 30+ year-old home

Siding Installation FAQ

How long does a full siding replacement take?
Most single-family homes take 1-3 weeks depending on size, complexity, and material. Fiber cement and cedar take longer than vinyl due to cut precision and finish work. Weather can extend timelines during wet stretches.

Do you install James Hardie?
Yes. We install James Hardie fiber cement products including HardiePlank lap siding, HardiePanel vertical siding, HardieShingle, and HardieTrim. We install both paintable and pre-finished (ColorPlus) product lines.

Do I need to repaint after new fiber cement siding is installed?
Not if you choose pre-finished (ColorPlus) — it arrives painted with a 15-year finish warranty. If you choose paintable primed Hardie, you'll want a quality exterior paint applied within the manufacturer-specified window after install.

Will you find dry rot under my old siding?
Very often, yes — especially on 25+ year old homes and around windows, doors, and bottom courses. We document any damage we find, show it to you, and provide a written change order before doing repairs. No surprise bills.

Do you pull permits for siding replacement?
Yes. Most jurisdictions in Clark County and Portland Metro require permits for full siding replacement, especially when re-flashing windows and doors. We handle all permitting.

What is a rain screen and do I need one?
A rain screen is a small air gap (usually 1/4" or 3/8") between the house wrap and the back of the siding, created with vertical furring strips. It lets the wall assembly drain and dry — critical in wet climates. We strongly recommend rain screens for all fiber cement and cedar installations in Clark County.

Can you side just one wall or side of my house?
Yes, though matching existing siding can be difficult if the original is faded or discontinued. We'll advise honestly whether partial replacement is a good idea or whether full replacement will look better and last longer.

Do you replace trim, soffits, and fascia during a siding job?
Almost always yes. Old trim, soffit, and fascia rarely last as long as siding — replacing everything at once ensures a clean, consistent look and full weather protection. We'll include this in your proposal.
