Granite Falls Siding Contractor — Mountain Foothills, Heavy Rain, Cedar & Hardie
Granite Falls is the last town before the Mountain Loop Highway heads into the Cascades. That foothill location means more rain, more tree canopy, and more moisture than anywhere in the lowlands. Homes here range from early logging-era houses to 1970s mountain retreats to newer builds on the outskirts. They all share one thing: heavy moisture exposure from every direction — rain from above, ground moisture from below, and damp air from the surrounding forest.

Real reviews from our Google profile — unedited, from real projects.
“We recently had Paul with GP General repair a damaged corner protector and sidings. His estimate was reasonable, his availability was timely, and his job was excellent. Our home hadn’t been re-painted in a while and the paint had considerably faded, yet he was able to match the color perfectly. Now we know who to turn to when in need of another repair work.”
“GP General replaced LP siding on our garage. Paul was very thorough when he came out to do the estimate; he listened to my concerns and was able to work out solutions on the spot. His crew did a great job and were very courteous. They also were careful about cleaning up (I didn’t find any nails!). Really happy with the job and can recommend GP General.”
“I highly recommend GP General Corp for siding replacement. We recently had our wood siding replaced with James Hardie lap siding, and Paul and his team did an excellent job.”

“Will they catch the damage I can’t see?”
Most siding fails because of what’s behind it — rot, failed flashing, moisture you can’t see from the curb. With 15+ years walking Snohomish County walls, we don’t guess. We probe, document, and re-engineer the wall assembly with drainable WRB, integrated flashings, and rainscreen ventilation built for Pacific Northwest weather.
Building Science First“I’m tired of high-pressure salespeople.”
No same-day discounts. No “this price is only good if you sign tonight.” We give you a free written assessment, a fixed-price contract, and the time to think it over. Most of our work in Granite Falls comes from neighbor referrals — you don’t earn that doing it any other way.
No-Pressure Quotes“Will the warranty actually mean anything?”
A warranty is only as good as the install behind it. We’re a certified James Hardie installer, which means every panel goes up to manufacturer spec — gap, fastener, primer, every detail. That’s what keeps your 30-year Hardie product warranty enforceable if you ever need to use it.
Manufacturer-Backed“How do I know they won’t disappear after the check clears?”
Owner-run with 15+ years of Snohomish County siding experience behind it. WA License #GPGENGC830KD backed by a $30,000 contractor bond — both verifiable any time at L&I. You’ll work with Paul start to finish. Same person quoting, walking the job, and answering the phone in year five if a question ever comes up.

Siding Materials for Granite Falls Homes
How We Do It
From permit to final walk-through, here’s exactly how a re-side in Granite Falls runs with GP General Corp.
We remove the existing siding completely and inspect every square foot of sheathing before anything new goes up. On Granite Falls homes we look specifically for extensive freeze-thaw damage at caulk joints from sustained cold-wet cycling, and snow-backup rot at the upper-wall eave transition. Any compromised sheathing is replaced with new plywood or OSB. This is where we find the hidden problems — failed flashings, missing WRB, saturated sheathing — that caused the old siding to fail in the first place.
We install Benjamin Obdyke HydroGap Drainable as our standard WRB on every job. The integrated drainage gap keeps any moisture that gets behind the siding moving down and out instead of sitting against sheathing. This matters for Granite Falls because of ~55 inches annually — among the wettest in our service area — with elevation-driven snow loading on upper walls. Seams are lapped upper-over-lower (6” horizontal, 12” vertical), taped at joints, and integrated with window and door flanges using peel-and-stick flashing.
Head flashings above windows and doors. Kick-out flashings at every roof-to-wall intersection. Step flashings along rooflines. Proper flashing integration at every penetration — vents, hose bibs, electrical boxes, light fixtures. On Granite Falls jobs we give extra attention to ice-and-water shield integration above roof-to-wall transitions and valley kick-outs on the short-span rooflines common in foothills designs. Failed or missing flashings are the number one cause of siding failure we see, so we upgrade these details beyond code-minimum wherever the install justifies it.
HardiePlank installed to James Hardie’s Best Practices manual for the HZ10 climate variant — the PNW-required product (HZ5 voids the warranty here). 1¼” corrosion-resistant nails, blind-nailed, ½” gap at trim, matched to your original reveal. We spec cold-climate WRB lap detail and use polyurethane sealants rated for freeze-thaw extremes instead of standard siliconized acrylic. ColorPlus pre-finish carries a 15-year color warranty; primed board gets field-painted within 180 days of install.
Every joint, butt-end, and penetration gets sealed with a high-grade elastomeric sealant rated for siding movement. The widest joint-cycling range in our service area — standard-grade sealant fails faster here than in Seattle, so sealant selection and bead size matter — we spec for the widest cycling range each Granite Falls elevation will see, not the average. Joints are tooled, not just applied, for full bond contact on both faces.
We walk the property with you at the end of the job to make sure everything looks great and you’re happy with the final result. It’s a 20-point walk: caulk lines, paint touchups, downspout reattachment, gutter reset, and site cleanup. Permit sign-off from the City of Granite Falls (or Snohomish/Skagit County on unincorporated properties) is documented and handed off to you.
The Siding Issues We Fix Most in Granite Falls
Heavy tree canopy and persistent moisture create ideal conditions for moss and algae on north-facing and shaded walls. This organic growth traps moisture against the siding surface, accelerating decay. We see cedar and LP siding rotting from the outside in on heavily shaded walls — a problem that barely exists in sunny lowland neighborhoods.
Cedar siding that lasts 30+ years in the lowlands can fail in half that time in Granite Falls if it wasn’t properly prepped. The heavier rain and slower drying time overwhelm unprimed or single-coat cedar. When we tear off failed cedar up here, the substrate behind it is usually in worse shape than we’d find on a similar home in Everett.
Foothill properties have higher water tables and more ground moisture than lowland lots. Splash-back from rain hitting landscape beds and decks keeps the bottom courses of siding damp. We see rot starting from the bottom up on nearly every tear-off in Granite Falls. Proper clearance and base flashing solve this.
What Granite Falls Homeowners Say
“Constant rain and heavy tree cover destroyed our cedar in 15 years. Paul installed Hardie with a rainscreen system and proper flashing everywhere. Two wet seasons in and the walls are bone dry behind the siding. He checked with a moisture meter.”
“Our north wall was covered in moss and the cedar was soft underneath. Paul replaced the sheathing and installed Hardie with extra attention to that wall. Explained why the shaded side needs different treatment. That level of detail matters up here.”
“Paul told us we didn’t need a full replacement — just the bottom four courses and the west wall. Saved us a lot of money by being honest. Fixed what needed fixing and left the rest alone. Rare find.”

Granite Falls Areas We Work In
The town center with a mix of early 1900s homes and mid-century builds. Some have original wood siding that’s held up surprisingly well; others need full tear-off and inspection. Walkable lots with reasonable access.
Properties heading toward the Cascades. Heaviest rainfall and densest tree canopy. Moss and organic growth are biggest challenges here. Enhanced moisture management on every installation.
Rural properties with larger lots in the Pilchuck River valley. Ground moisture is high, and the forest keeps things damp. Siding-to-grade clearance and proper drainage are critical in this area.
Mix of newer rural homes and established properties. Some newer builds used LP or vinyl that’s already showing moisture stress in the heavier foothill climate. Good candidates for proactive replacement.
