SEALCOAT + RESTRIPE IN ONE VISIT — SAVE ON MOBILIZATION — FREE QUOTES IN 24 HOURS
Northwest Washington's wet winters and freeze-thaw cycles destroy unprotected asphalt fast. Professional sealcoating is the single highest-ROI maintenance step for any parking lot — and paired with fresh line striping, it transforms your property in one day.
Sealcoating blocks UV oxidation, water infiltration, and fuel/oil spills — the three main causes of premature asphalt failure in the PNW. A sealed lot can outlast an unsealed one by 10–15 years.
Our most popular service. Fresh sealcoat followed by crisp line striping, ADA markings, fire lane stencils, and directional arrows — all in a single visit. One mobilization, one invoice.
We hot-pour fill cracks before applying sealcoat, preventing water from reaching the asphalt base during Whatcom County's wet season. Skipping this step is the #1 reason sealcoating fails early.
Property managers across NW Washington put their lots on a 3–5 year sealcoating schedule with us. We track your lot and reach out when it's time — no guesswork required.
Every sealcoat job can include fresh ADA-compliant stall markings, van-accessible spaces, and required signage — so your lot is protected and legally compliant when we leave.
We work nights and weekends to avoid disrupting your business. Most commercial lots are sealed and restriped within 1–2 days with vehicle traffic restored in 24–48 hours.
Northwest Washington gets 35–45 inches of rain per year. Unprotected asphalt absorbs that water, which works into cracks, freezes, expands, and destroys the pavement base from the inside. Sealcoating is the waterproof barrier that stops this cycle.
Commercial-grade sealers selected for Whatcom County's rain and freeze-thaw environment — not big-box store product.
Because line striping is our core business, your restripe after sealcoating is done by the most experienced crew in the region.
Fully licensed (#LINEMS*750QM), bonded, and insured. Washington State contractor you can verify.
Most property managers don't realize that sealcoating and line striping go hand-in-hand. Every time you sealcoat, your old lines are buried under the new sealer — meaning restriping isn't optional, it's required. By bundling both into one visit, LineMark saves you the cost and hassle of a second mobilization. One invoice, one crew, one visit.
In the Pacific Northwest, we recommend sealcoating commercial parking lots every 3–5 years. High-traffic lots (grocery anchors, gas stations, fast food) may need sealing every 2–3 years. Lower-traffic office or HOA lots can often go 5 years. The key is applying before the pavement grays out and cracks begin to propagate.
LineMark is based in Lynden, WA and serves commercial sealcoating customers across all five counties: Whatcom (Bellingham, Ferndale, Blaine, Birch Bay), Skagit (Mount Vernon, Burlington, Anacortes), Snohomish (Everett, Marysville, Lynnwood), Island (Oak Harbor, Coupeville, Camano Island), and San Juan County. Ferry-coordinated scheduling for island jobs.
Commercial sealcoating typically runs $0.12–$0.25 per square foot. A combined sealcoat + restripe package for a 20,000 sq ft lot generally falls between $3,000–$6,500 depending on surface condition and scope. Get an exact quote — free, no obligation, response within 24 hours.
