Lynnwood Siding Contractor — Siding Replacement & Installation
Need a Lynnwood siding contractor who knows 70s-era homes? Lynnwood’s housing stock has a specific problem: median construction year is 1979. That means cedar bevel, T1-11, and original hardboard siding — nearly 50 years old, well past replacement age, and in many cases hiding rotted sheathing. Add the wind-driven Puget Sound rainfall on west-facing walls, and most homes here need full siding replacement, not patches. Paul knows the era, the materials, and the failure modes — from siding repair to complete Lynnwood siding installation.

“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 Lynnwood 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 We Install in Lynnwood
Our Siding Installation Process in Lynnwood
From permit to final walk-through, here’s exactly how a siding installation or siding replacement in Lynnwood runs with GP General Corp.
We remove the existing siding completely and inspect every square foot of sheathing before anything new goes up. On Lynnwood siding replacement projects — most homes built in the 1970s and 80s — we expect to find rotted sheathing at lower courses, around windows, and behind hardboard joints. Replacement of saturated plywood or OSB is part of the budget, not a surprise. This is where we find the hidden problems that caused the original siding to fail.
We install Benjamin Obdyke HydroGap Drainable as our standard WRB on every Lynnwood siding installation. The integrated drainage gap keeps any moisture that gets behind the siding moving down and out instead of sitting against sheathing. Most 70s Lynnwood homes never had a true WRB — just felt paper, now disintegrating. The drainable layer is a generational upgrade for these walls. Seams lapped 6” horizontal, 12” vertical, taped at joints, integrated with window and door flanges.
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. On Lynnwood mid-century homes, we frequently rebuild flashings entirely during siding repair — the original installs relied on tar paper and caulk. Failed or missing flashings are the number-one cause of siding failure we see.
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 replace saturated OSB sheathing with plywood on north-wall sections where prior moisture has already weakened the substrate. 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. Lynnwood’s wind-driven rain off Puget Sound is harder on sealant than the drier inland weather, so we spec for the worst-case bead width on every Lynnwood siding installation, and 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 your Lynnwood siding installation 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 Lynnwood (or Snohomish County for unincorporated parcels) is documented and handed off to you.
The Siding Issues We Fix Most in Lynnwood
Lynnwood’s median home is 47 years old. Original cedar bevel, T1-11, hardboard, and aluminum siding are all well past their service life. We rarely see Lynnwood homes that don’t need full siding replacement — the condition typically isn’t fixable with paint or repair.
Many 70s Lynnwood homes used Masonite hardboard, which absorbs water at the bottom edge of every plank. Once swelling starts, paint can’t restore it. We’ve found planks 80% delaminated under fresh paint during siding repair calls. Replacement is the only fix.
Lynnwood’s proximity to Puget Sound means west-facing walls take direct wind-driven rain in winter storms. Standard caulk and nail patterns aren’t enough — we’ve seen complete sheathing rot on west elevations of homes whose other three sides were fine.
What Lynnwood Homeowners Say
“Alderwood Manor home from 1976, original cedar bevel, north side rotted through. Paul replaced sheathing, did proper flashings, and installed Hardie HZ10. The whole house feels solid for the first time in years.”
“Our Meadowdale split-level had original 1979 hardboard. Bottom courses were swollen, the corner trim was disintegrating. Paul did the full tear-off, found rotted plywood, and rebuilt the wall correctly. Should have done this 10 years ago.”
“Lynnwood Heights 1980 home, T1-11 plywood siding. Bottom edges were rotted, west wall had visible water staining. Paul handled it from permit to final inspection without me chasing anything down. Worth every dollar.”
