“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.”

Why GP General Corp

Why Kirkland Homeowners Trust Us With Their Siding

You’ve probably gotten a few quotes for Kirkland siding contractor work already. You’ve heard the pitches. Here’s what makes us different — and why Kirkland homeowners don’t shop around the next time.

Recent GP projects on the Eastside & nearby:

01

“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 Eastside 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
02

“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 Kirkland comes from neighbor referrals — you don’t earn that doing it any other way.

No-Pressure Quotes
03

“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
04

“How do I know they won’t disappear after the check clears?”

Owner-run with 15+ years of Eastside 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.

Common Problems

The Siding Issues We Fix Most in Kirkland

Rot Behind Good-Looking Paint — siding issue on Kirkland home, GP General Corp inspection
Rot Behind Good-Looking Paint

The most common find: siding that looks fine from the sidewalk but is rotting from behind. Paint outlasts the wood underneath. You don’t know until you push on a board and your thumb goes through. Especially on north walls and anywhere with overgrown landscaping.

Failed 90s Hardboard — siding issue on Kirkland home, GP General Corp inspection
Failed 90s Hardboard

Rose Hill and Bridle Trails have homes built with LP Inner-Seal — pressed-wood siding that absorbs moisture, swells, and crumbles. The class-action deadline passed years ago. If your siding is bubbling at the bottom edges, that’s what you’re dealing with. It needs to come off.

No Weather Barrier — siding issue on Kirkland home, GP General Corp inspection
No Weather Barrier

Older Kirkland homes — Juanita, Norkirk, Houghton — often have siding nailed directly to sheathing with no house wrap. Every nail hole becomes a water path. A proper WRB system goes on first during any re-side we do.

Installation Process

How We Do It

From permit to final walk-through, here’s exactly how a re-side in Kirkland runs with GP General Corp.

Siding tear-off and substrate inspection
01
Tear-Off and Substrate Inspection

We remove the existing siding completely and inspect every square foot of sheathing before anything new goes up. On Kirkland homes we look specifically for LP Inner-Seal or T1-11 hardboard failure in 80s/90s Rose Hill and Bridle Trails homes — swollen bottom edges and crumbling at ground-contact lines. 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.

Weather resistive barrier WRB installation
02
Weather-Resistive Barrier (WRB) Installation

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 Kirkland because of ~40 inches annually, with wet-side exposure to winter storms tracking in off Lake Washington. 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.

No Weather Barrier — siding issue on Kirkland home, GP General Corp inspection
03
Flashing at Every Transition

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 Kirkland jobs we give extra attention to window sill pan flashings on older 50s–60s bungalows that originally relied on caulk beads. 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.

Board Installation to Hardie Spec

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 size WRB coverage to overlap any remaining areas of original siding we aren’t replacing, so the moisture plane is continuous. ColorPlus pre-finish carries a 15-year color warranty; primed board gets field-painted within 180 days of install.

Caulking and joint treatment on James Hardie siding — Seattle siding contractor GP General Corp
05
Caulking and Joint Treatment

Every joint, butt-end, and penetration gets sealed with a high-grade elastomeric sealant rated for siding movement. Waterfront-adjacent elevations see more salt-air influence than the rest of the Eastside, so sealant selection and bead size matter — we spec for the widest cycling range each Kirkland elevation will see, not the average. Joints are tooled, not just applied, for full bond contact on both faces.

Final Walk-Through

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 Kirkland (or Snohomish/Skagit County on unincorporated properties) is documented and handed off to you.

FAQ

Kirkland Siding Questions

Do I need a permit to replace siding in Kirkland?
Yes. Kirkland requires a building permit for full siding replacement, including an inspection of the moisture barrier. Fees run $300–$600. We handle the application and inspection scheduling — it’s included in your quote.
My HOA requires design review. Can you handle that?
We do this regularly in Rose Hill, Bridle Trails, and other Kirkland communities. We prepare the full submission — material specs, color samples, product data sheets, installation details. Most boards approve on the first round because we give them everything upfront.
My siding looks fine outside. How do I know if there’s a problem behind it?
That’s the most dangerous situation — paint outlasts the wood underneath. Warning signs: soft spots when you push, bubbling paint, musty smell near walls, gaps opening at joints, moisture staining inside the house. Paul probes suspect areas with a moisture meter during the free visit.
What’s the difference between HZ5 and HZ10 Hardie boards?
HZ10 is built for our climate — sustained rain plus freezing nights. HZ5 is cheaper, made for mild climates. If HZ5 goes on your Kirkland home, your Hardie warranty is void from day one. We verify every pallet is HZ10 and photograph the stamps for your records.
How long does a full siding replacement take?
Most Kirkland homes: 2–4 weeks depending on size and substrate condition. Lakefront homes in Houghton take longer due to access and complexity. The timeline is in your written quote.
How much does it cost to side a typical Kirkland home?
A typical 2,500 sq ft Kirkland home (about 3,750 sq ft of wall area) runs $52,000–$75,000 for a full re-side with James Hardie fiber cement installed. Pricing per square foot of wall area:
  • James Hardie fiber cement (with HydroGap Drainable WRB + vented rainscreen) — $14–$20/sf installed
  • Cedar or Lunawood thermally-modified wood$20–$40/sf installed
  • Hardie Artisan or standing-seam metal$30–$55/sf installed
Kirkland homes vary widely — a small Highlands rambler can land under $40K, while a Houghton or Yarrow Bay lakefront home with custom trim runs $120K+. We measure exact wall area on the free assessment so the quote isn’t guessed from the floor plan.
What is the best time of year to install siding in Kirkland?
May through October is the best window for siding installation in Kirkland, with the driest stretch in late July and August. Kirkland’s lakefront neighborhoods (Houghton, Yarrow Bay, Juanita) catch wind off Lake Washington that drives rain into west-facing walls in winter, so winter installs in those areas carry more weather risk than inland Kirkland. We work year-round with strict dry-in protocol — tarp at sundown, never start tear-off into a 48-hour rain forecast.
Does Kirkland have specific siding material rules near Lake Washington?
Kirkland does not restrict siding material choice on standard residential lots, but lots within shoreline buffer zones (typically within 200’ of Lake Washington) are subject to Shoreline Master Program review for any envelope work. Standard upland Kirkland re-sides go straight to install without shoreline review. If your home is on the lakefront or within the 200’ buffer, the project may require a Shoreline Substantial Development exemption from the City of Kirkland Planning Department — we handle that filing if applicable. Your HOA (Houghton Beach Park, Yarrow Bay) may have additional design review requirements above the city’s rules.
Local Knowledge

Kirkland Neighborhoods We Work In

Juanita & South Juanita

1960s–70s ranchers and split-levels with original cedar or hardboard. Lake moisture from the west, tree shade behind. We’ve found rot running full walls along 98th Ave NE — hidden behind paint that still looked fine from the street.

Houghton & Lakeview

Waterfront homes from the 1950s–80s. Lake Washington exposure means wind-driven rain on the west face and condensation in winter. Hardie or standing seam metal are the two materials that hold up here.

Rose Hill & Bridle Trails

1990s–2000s construction with LP Inner-Seal siding that’s now delaminating across the neighborhood. HOAs require design review — we handle the full submission paperwork.

Norkirk & Market District

Kirkland’s oldest — Craftsman cottages and vernacular homes from the early 1900s. Many have layers of siding stacked on top of each other from 3–4 generations of re-siding. Tearoff can uncover surprises.

Finn Hill & Kingsgate

Large wooded lots with mature Douglas fir canopy. Persistent shade, moss buildup, and branch-strike damage. Hilltop homes in Kingsgate get wind-driven rain at roof-wall junctions that most contractors miss during inspection.

Totem Lake & Everest

Mixed housing ages near the commercial core. Newer developments with typical HOA oversight. Older homes on surrounding streets often have deferred maintenance — siding that should have been addressed years ago.

Kirkland Neighborhoods, Permits, and Housing Stock We Work With

Kirkland’s housing stock is older than Bellevue’s and more varied than Redmond’s — there’s pre-1950s historic stock down by Moss Bay, 1960s–70s mid-century in Houghton, 1980s–90s tract in Rose Hill and Finn Hill, and waterfront homes along Lake Washington and Juanita Bay that have their own salt-air maintenance profile. The siding decisions on each are different.

Moss Bay, downtown Kirkland, Norkirk

The downtown Kirkland and Moss Bay neighborhoods have homes from the 1920s through the 1950s — narrow lots, smaller floor plates, tongue-and-groove cedar or original wood lap siding on many of them. These are the homes where a careful cedar restoration with six-side priming and stainless ring-shank fasteners makes more sense than a full Hardie conversion; the architectural character is part of the property value, and Hardie’s smooth profile doesn’t read right on a 1930s craftsman. We do these jobs slower and with more board-by-board care.

Houghton, Lakeview, Highlands

The Houghton neighborhood south of downtown is mostly 1950s–1970s mid-century homes — flat-roof and shed-roof stock with horizontal lap or T1-11 siding original. The 1970s T1-11 in particular is failing fast across this part of Kirkland; the plywood face delaminates, fasteners loosen, and the substrate beneath has often gone soft from years of paint failure water intrusion. Most Houghton clients we see end up replacing the entire wall assembly back to the studs.

Juanita, Finn Hill, Totem Lake

North Kirkland — Juanita, Finn Hill, and the Totem Lake corridor — is mostly 1980s and 1990s tract construction. LP Inner-Seal hardboard was the dominant cladding here in that era, and its failure mode is now well-documented: bottom-edge swelling, paint failure at horizontal joints, and dimensional instability that opens caulk seams. Hardie HZ10 fiber cement is the standard replacement, with HydroGap Drainable WRB and a ventilated rainscreen added in the wall assembly that almost certainly didn’t have one originally.

Rose Hill, Kingsgate, eastern Kirkland

The eastern Kirkland neighborhoods extending toward the Bellevue line — Rose Hill, Kingsgate, and the eastern Kirkland edge — share the 1980s–90s tract pattern with Juanita but tend toward larger floor plates and more architectural complexity at the rooflines. Multiple gable-to-wall intersections per elevation means more kickout flashing locations, and missing kickouts are the single most common cause of hidden rot in this part of Kirkland.

Working with the Kirkland Permit Center

Kirkland’s Building Services counter on Kirkland Way handles permits through the City’s eTRAKiT online portal. For full re-sides, we submit through eTRAKiT with cladding specs, the WRB system cut sheet, and detail drawings showing flashing at every window, door, and roof-wall transition; review timelines run 2–3 weeks for straightforward residential. Localized repair work under the structural threshold is typically over-the-counter and same-day. As a fully licensed and bonded WA contractor, we pull and close every Kirkland permit ourselves — homeowners don’t have to navigate the process.

The local moisture pattern

Kirkland’s microclimate is moderated by Lake Washington — slightly drier than Sammamish, slightly warmer than Bothell. The exception is the lakefront and Juanita Bay margin, where airborne salt and constant lakeshore humidity attack fasteners. We use 316-grade stainless ring-shank fasteners on all waterfront installs, never galvanized. The most common rot pattern we find behind Kirkland cladding is cedar siding at northeast-facing corners where rain hits hardest and sun reaches latest in the day, allowing capillary moisture to remain in the boards days after the rain stops.
