THE PROJECT, WEEK BY WEEK

What a Whatcom County Re-Side Actually Looks Like

From first walkthrough to final city inspection — the sequence is the same on every home; only the rot repair in the middle varies.

1

On-Site Estimate & Written Bid

WEEK 0

We walk every elevation of your Whatcom County home, measure, and write an itemized bid specific to the house — product recommendations included, boilerplate not.

2

Permit & Materials

WEEKS 1–3 BEFORE START

The right permit pulled for your address — city permit counters in Bellingham, Ferndale, and Lynden, Whatcom County PDS for unincorporated parcels, and a re-side needs one on either side of that line — and materials ordered so nothing stalls mid-project.

3

Tear-Off & Sheathing Inspection

DAYS 1–3

Old siding comes off completely. Sheathing and framing get inspected wall by wall; rotted sheathing is typically replaced at no extra cost on a full-home re-side, and anything past the sheathing, which is very uncommon, is photographed and quoted as a change order for your approval before we rebuild.

4

Weather Barrier, Flashing & New Siding

DAY 3 ONWARD — PACED TO THE PROJECT

The layers that matter go on: weather barrier lapped for wind-driven rain, flashing at every penetration, then siding fastened to manufacturer spec. Walls are dried in the same day they're opened.

5

Cleanup, City Inspection & Walkthrough

FINAL DAYS

Magnet sweep and full site cleanup, final municipal inspection passed, and a walkthrough with you — touch-ups handled on the spot, warranty paperwork in hand.

What Drives the Price of a Whatcom County Re-Side

No two bids should look alike, because no two houses do. In Whatcom County the big variables are the ones below — and every one of them is itemized in your written estimate, so you can see exactly where the number comes from.

Home Size & Stories
Wall area drives material; height drives staging and labor. Whatcom County's hillside homes often price higher per square foot than flat-lot ranches.
Housing Era
Pre-1978 homes need lead-safe practices (we're a certified firm); craftsman-era trim detail takes more time than 1990s subdivision profiles.
Rot Repair
The genuine unknown. Weather-facing walls — bayfront or wind-raked farm country — usually carry some, photographed and priced before rebuild, never buried in the bid.
Material Choice
Fiber cement costs more per square foot than engineered wood but ends the repaint cycle. We quote options side by side so the trade-off is yours.
What We Find Under Whatcom County Homes

Whatcom County's mix of century-old craftsmans and '80s–'90s LP-era homes means we regularly open walls to find bottom-course rot on bay-facing elevations, swollen sheathing behind failed seams, and older tar-paper barriers long past their service life. The terrain adds its own patterns: salt-corroded fasteners near the Blaine and Birch Bay shoreline, wind-worked seams in the Lynden flats, and moss-fed moisture on shaded Lake Whatcom and South Fork lots.

Whatever we find is photographed and priced before rebuild — never a surprise on the invoice.

Can You Re-Side in the Rainy Season?

Yes — we re-side Whatcom County homes year-round. Walls are opened in sections and dried in the same day, never left exposed overnight. Winter scheduling is often faster to book; the detailing that keeps a wall dry for thirty years doesn't care what month it went on.

WHY WE RECOMMEND FIBER CEMENT

Our Recommendation for Whatcom County: James Hardie Fiber Cement

We recommend fiber cement — James Hardie specifically — and it’s the only siding we recommend for Whatcom County homes. In a wind-driven-rain state, fiber cement doesn’t rot, doesn’t feed moss, doesn’t warp, and shrugs off the freeze-thaw cycles that crack lesser boards. It carries a 30-year limited warranty on the boards, and ColorPlus factory finishes carry their own 15-year limited finish warranty.

As a James Hardie Elite Contractor we install to the spec that keeps that warranty valid — fastening, clearances, and flashing details checked on every wall. For Whatcom County homes, Hardie is the answer we’d put on our own house.

THE HONEST NUMBERS
01 · PRICING

What Siding Replacement Costs in Whatcom County

Most single-family whole-home projects typically land between $20,000 and $60,000. Home size and stories move the number most; the other big lever is combining windows with the re-side — window replacement runs typically 20–35% less per window during a siding project, since demolition, disposal, and admin overhead are already covered.

Prices change often with inflation, material costs, the economy, and tariffs and other policy changes, so these ranges are a guide, not a quote. Your written estimate has the current price for your home.

Nationally, fiber cement siding replacement is one of the best-returning exterior projects at resale — recent Cost vs. Value Report data puts its cost recoup above 100% (a national figure; local results vary). Every bid is measured at your home and itemized — sheathing rot repair is typically included on a full-home re-side, and anything past the sheathing is photographed and quoted as a change order, never buried. Financing options are available.

02 · TIMELINE

How Long a Re-Side Takes

Typically one to four weeks on site for a full home, depending on size, sheathing condition, how much rot we find, and whether we're painting.

The schedule is written into the bid, and the final inspection is part of it — the job is not done until it passes.

03 · WARRANTIES

What Stands Behind the Work

James Hardie siding carries a 30-year substrate warranty, with ColorPlus finishes warranted for 15 years.

Our own workmanship warranty is included on every project — terms spelled out in your bid.

FAQ

Replacing Siding in Whatcom County — The Practical Questions

Prefinished James Hardie siding typically runs $11–$16 per square foot of wall, installed with the tear-off of the old siding, and most single-family whole-home re-sides typically land between $20,000 and $60,000. By home size, before sales tax: about a 1,500 sq ft home typically runs $25,000–$38,000, about 2,000 sq ft $28,000–$45,000, and about 2,500 sq ft $38,000–$50,000. How much wall the home has, and how many stories, move the number most. Sales tax is added on the whole job at your address's rate, which right now runs from 8.3% to 9.3% across Whatcom County. Rates change, so check the Washington Department of Revenue's website for the current rate at your address. Every bid is measured on site and itemized, and financing is available.
