Lynden Siding Vinyl siding shows up on a lot of quote requests we get in Lynden, and we understand why. It's inexpensive, it's widely available, and the sales pitch — "never paint again" — is appealing. We're not going to pretend vinyl is a bad product for every climate in the country. But we don't install it here, and we think homeowners deserve the honest reasons why, not just a sales brochure.
What Vinyl Gets Right
Vinyl siding is lightweight, it's the cheapest siding option on the market, and it genuinely doesn't need repainting the way wood does. For a homeowner on a tight budget in a mild, dry climate, that combination can make sense. Our objection isn't that vinyl is junk — it's that Whatcom County's weather exposes exactly the weaknesses vinyl has, year after year.
Thermal Movement and Cracking
Vinyl is plastic, and plastic expands and contracts with temperature swings more than any other siding material. It's installed with a "hanging" nail-hem system specifically to allow that movement — which means it's never truly rigid on the wall. When we get a hard cold snap off the Fraser Valley, older or lower-grade vinyl gets brittle and can crack from something as minor as a bumped ladder or a wind-thrown branch. Once a panel cracks, it doesn't patch — the whole piece has to come off and be replaced, and matching faded vinyl to a panel that's been in a box for years rarely looks seamless.
Fading You Can't Fix
Vinyl color runs through the material, which sounds durable, but UV exposure still fades it over time, and manufacturers generally advise against painting vinyl because dark paint absorbs heat the panel wasn't engineered to handle — it can warp. So once vinyl fades unevenly, which it does, especially on south and west-facing walls, your only real fix is replacement.
Moisture Behavior in a Wet Climate
Vinyl siding isn't a weather barrier by design — it's a rain screen that relies on a correctly installed drainage plane behind it to do the real work of managing water. That's fine in theory, but it puts almost all the responsibility on installation quality, and vinyl is unforgiving of shortcuts. Panels installed too tight don't allow for expansion and can buckle; panels installed too loose let wind-driven rain get behind them. In a place like Lynden, where driving rain off the Salish Sea is a normal part of the winter forecast, a siding system with that little margin for error concerns us.
Moss, Algae, and the Long Whatcom Season
Whatcom County's moss season runs long — shaded, tree-lined lots and north-facing walls stay damp for months at a stretch. Vinyl's overlapping panels and horizontal laps create shadowed ledges that hold moisture, and the smooth plastic surface gives algae and moss spores an easy place to grab hold. It's not that vinyl "grows" moss any more than other materials, but the panel geometry and the local climate combine to make it a common maintenance headache we hear about from homeowners looking to switch.
Wind, Impact, and Fire
Because vinyl panels hang loose in a track rather than being fastened rigidly, they can rattle, bow, or blow off entirely in a strong windstorm — something coastal Whatcom County properties deal with more than most. Vinyl also has no fire resistance to speak of; it's plastic, and it will melt or ignite from a nearby fire pit, grill, or ember in a way that non-combustible materials simply won't. Between salt-tinged coastal air, storm exposure, and wildfire smoke seasons becoming more common in the Pacific Northwest, we'd rather put a non-combustible product on a home.
Warranty Fine Print
Vinyl warranties often read better than they perform. Many are prorated, meaning the payout shrinks every year you own the home, and fade coverage frequently excludes darker or premium colors — the ones homeowners actually want. Transferability to a new owner, if it exists at all, is usually limited and time-boxed.
Why We Standardized on James Hardie Instead
We made a decision as a company to install James Hardie fiber cement exclusively, and vinyl's trade-offs are a big part of why. Hardie's HZ5 product line is climate-engineered for wet, marine-influenced regions like ours, the ColorPlus factory finish is baked on rather than painted or dyed through plastic, and fiber cement is non-combustible — it won't melt, warp, or ignite from routine heat exposure. It's also rigid and fastened directly to the wall rather than hung loose, which holds up better against wind and impact. None of that makes Hardie maintenance-free, and it costs more upfront than vinyl. But for a home that has to stand up to Whatcom County rain, wind, and a long moss season for decades, we think it's the honest choice.
