Glenhaven Siding One Product, One Standard
Homeowners sometimes ask why we don't offer a menu of siding options the way some contractors do. The honest answer is that we spent enough years repairing and replacing siding in Glenhaven and the surrounding parts of Whatcom County to develop strong opinions about what actually holds up here. James Hardie fiber cement is the only siding we install, and this page explains the reasoning rather than just asserting it.
What Our Climate Does to Siding
Glenhaven sits close enough to the water that salt air is a real factor in how exterior materials age. Add in driving rain that comes sideways off Puget Sound weather systems, plus a moss season that can stretch from fall through spring in the shaded, damp lots common around this part of Whatcom County, and you get a climate that's hard on anything with a weak point. Wood-based products can swell, delaminate, or rot at cut edges and fastener lines. Vinyl can warp, fade, or crack in temperature swings and impact. Not every fiber cement product is engineered the same way, either — thickness, edge sealing, and finish quality vary by manufacturer.
Why We Standardized on James Hardie
We didn't start as a Hardie-only contractor. We got there after seeing which products kept performing after ten and fifteen years on real homes, and which ones needed early repainting, caulking, or panel replacement. Four things drove the decision:
- Non-combustible core. Fiber cement doesn't burn, which matters to insurers and to homeowners thinking about wildfire-adjacent risk even in a wetter climate like ours.
- Factory-applied ColorPlus finish. Instead of field-painted siding that starts weathering the day it's installed, ColorPlus is baked on at the factory with a finish designed to resist fading and chipping far longer than site-applied paint.
- Climate-engineered HZ product lines. Hardie makes different formulations for different regions — HZ5 for colder, wetter climates like ours versus HZ10 for hot, dry ones. That's an acknowledgment that siding needs to be engineered for where it's actually installed, not treated as one-size-fits-all.
- A warranty structure that's transferable and backed by a large manufacturer. That matters when a home sells within the warranty period, which happens often in this market.
The Hardie Product Lines We Work With
Hardie isn't a single product — it's a system with options that fit different home styles:
- HardiePlank lap siding — the most common choice, available in several exposure widths and textures including smooth and cedar-grain.
- HardiePanel — vertical panel siding often used for board-and-batten looks or as an accent alongside lap siding.
- HardieShingle — for homes that want a shingle-style look without the maintenance burden of real wood shingles in a moss-prone climate.
- HardieTrim — matching trim boards that finish out corners, window surrounds, and fascia in the same material family so everything ages consistently.
Color and Finish
The ColorPlus line comes in a curated palette designed to work well with Pacific Northwest architecture and light. Because the finish is factory-applied under controlled conditions, color consistency from board to board is better than what you typically get from job-site painting, and touch-up products are formulated to match rather than requiring a full repaint.
Installation Is Half the Product
Fiber cement is only as good as its installation. Correct fastener placement, proper clearance from grade and roof lines, factory-cut versus field-cut edge treatment, and correct caulking at joints all affect how the siding performs through our wet season. A lot of the maintenance problems we get called out to fix on other contractors' Hardie jobs trace back to installation shortcuts, not the material itself. We install to Hardie's published specifications because that's what the warranty requires and because it's what actually keeps water out of the wall assembly.
What Hardie Doesn't Solve
We're not going to oversell this. Fiber cement is heavier than vinyl and requires proper flashing and house-wrap detailing behind it, same as any siding. It's not maintenance-free — it should be inspected periodically and caulked joints checked, especially in a climate that keeps siding wet for long stretches of the year. What it doesn't do is rot, feed insects, or need repainting every several years, which is where it earns its keep over a few decades on a Glenhaven home.
Our Position
We turned down installing LP SmartSide, vinyl, Cemplank, Allura, primed spruce, and cedar as company policy — not because every one of those products is bad in every application, but because after years of callbacks and warranty headaches, Hardie was the one product we could stand behind on every home we touch in this climate. Standardizing on one system also means our crews install it correctly every time instead of switching techniques between materials.
