Types of Siding Projects
Most siding work falls into one of three levels. The level decides the budget and what we can inspect behind the siding.
| Project Type | What Changes | Best For |
|---|---|---|
| Siding repair | Damaged boards replaced and the leak behind them fixed | Isolated damage on siding that’s otherwise sound |
| Partial replacement | One or more walls stripped and re-sided | Weather-facing walls that failed first |
| Full replacement | All siding removed; sheathing repaired; new barrier, flashing, siding, and trim | Worn, rotting, or outdated siding, or a new look for the whole house |
When Is It Time to Replace Your Siding?
- Soft or swollen boards: water is getting into the siding and possibly the wall behind it.
- Paint won’t hold: peeling paint soon after painting often means moisture behind the siding.
- Gaps, cracks, or loose boards: openings that let rain reach the wall.
- Moss, mold, or stains: especially on north-facing and shaded walls.
- Leaks around windows: stains inside near windows often trace back to failed flashing.
- You’re planning to sell: siding is the first thing buyers see.

Siding Built for Northwest Rain
Siding sheds most water, but not all of it. In a region with about 39 inches of rain a year spread over many damp days, what’s behind the siding decides whether your walls stay dry.
| Detail | What We Do | Why It Matters |
|---|---|---|
| Water-resistive barrier | A continuous barrier over the sheathing, lapped to shed water | Catches the water that gets past the siding |
| Window and door flashing | Flashing integrated with the barrier at every opening | Openings are the most common leak points |
| Sheathing inspection | Old siding comes off so we can find and repair rot | New siding over damaged sheathing fails early |
| Ground and roof clearances | Siding kept off soil, paving, and roof surfaces per the manufacturer | Prevents wicking and keeps the warranty valid |
| Manufacturer installation | Fastening and gapping per the siding maker’s instructions | Siding warranties depend on proper installation |
Permits & Rules for Siding in Washington
Siding rules differ by city more than most people expect, and a state rule applies before old siding comes off.
| Rule | When It Applies | What It Means for Your Siding |
|---|---|---|
| Seattle | Replacing siding with no structural changes | No permit required |
| Other cities | Some Washington cities treat siding replacement as permitted work | A building permit, sometimes with a barrier inspection; we check your city |
| Structural or opening changes | New or larger windows and doors, or framing repairs | Usually a building permit |
| Asbestos survey | Before renovation or demolition in the Puget Sound region | Required by Puget Sound Clean Air Agency and L&I rules before tear-off |
Our Siding Process
Step 1: Free In-Home Estimate
We walk the exterior, check for damage and leaks, talk through materials and colors, and send a written quote.
Step 2: Selections & Permits
You choose the siding, trim, and color; we handle the asbestos survey and any permit your city requires.
Step 3: Site Protection & Tear-Off
We protect landscaping and remove the old siding.
Step 4: Sheathing Repair
Any rot or damage is repaired before anything new goes on.
Step 5: Barrier, Flashing & Siding
New water-resistive barrier, flashing at every opening, then siding and trim.
Step 6: Cleanup & Final Walkthrough
We clean the site and review every wall with you.
Siding Cost – What to Expect
Every siding project is priced individually, because the house and the material decide the cost. You get a realistic estimate for your home, in writing, before work begins.
| Price Factor | Effect on Cost | Why It Matters |
|---|---|---|
| House size and stories | More wall area and height mean more material, labor, and staging | Two-story walls need scaffolding or lifts |
| Siding material | Vinyl usually costs least; fiber cement and cedar cost more | Material also decides future upkeep |
| Trim and openings | More windows, doors, and corners add detail work | Each opening needs flashing and trim |
| Hidden damage | Rotted sheathing must be repaired first | Fixing it now keeps the new siding from failing |
| Old siding removal | Tear-off and disposal; an asbestos survey comes first | Older siding may need special handling |

FAQ – Siding
How much does new siding cost?
It depends on the size of the house, the siding material, how much trim and how many windows there are, and what we find under the old siding. Every project gets a written quote after a free in-home estimate, and financing is available.
What is the best siding for the Pacific Northwest?
The best siding for our rain is one that resists moisture and is installed over a proper water-resistive barrier with flashing. Fiber cement and engineered wood are popular low-maintenance choices; cedar offers a natural look but needs regular finishing.
Fiber cement or engineered wood siding?
Both are durable, paintable, and come in lap, panel, and shake styles. James Hardie fiber cement lap siding carries a 30-year limited warranty that isn’t prorated, while LP SmartSide engineered wood carries a 5/50-year limited warranty: full labor and material coverage for 5 years, then prorated coverage to 50 years.
Do I need a permit to replace siding in Washington?
It depends on your city. Seattle does not require a permit to replace siding when no structural changes are made, while some Washington cities require a building permit with a water-resistive barrier inspection. We check your city’s rules at the estimate and handle any permit.
Can new siding go over my old siding?
We usually recommend removing the old siding so we can inspect the sheathing, repair hidden water damage, and install a new water-resistive barrier and flashing. Covering old siding can hide the very problems that cause rot.
Is an asbestos survey required before replacing siding?
In the Puget Sound region, Puget Sound Clean Air Agency and Washington L&I rules require an asbestos survey before renovation or demolition. Some older siding contains asbestos, so the survey comes before any tear-off.
Should I replace my windows when I replace siding?
It’s often the best time. With the siding off, new windows can be flashed and sealed into the water-resistive barrier properly, which is harder to do later without disturbing the new siding.
