Our Services

Island-Tough Roofing Solutions

Alpine Siding Pros installs premium asphalt shingle and standing-seam metal roofing engineered to resist Lummi Island’s salt spray, heavy rains, and wind gusts. Our certified crews conduct thorough deck inspections, apply marine-rated underlayment, and seal all flashings with corrosion-resistant sealants to prevent leaks and ice dams.

Every project begins with a detailed structural assessment to uncover hidden rot or deck damage. We include courtesy rot repair at a nominal fee and back our workmanship with manufacturer warranties—ensuring your new roof protects your home and preserves its seaside charm for decades.

Marine-Grade Siding Installations

Shield your Lummi Island property with low-maintenance vinyl, fiber cement, or engineered wood siding from Alpine Siding Pros. Our installers achieve millimeter-perfect trim alignment, install continuous waterproofing membranes, and caulk every seam to block moisture, drafts, and salt intrusion in the coastal environment.

We start each siding job with substrate and sheathing inspections. By pairing top-tier materials with our perfected moisture-barrier techniques, we deliver an energy-efficient, mold-resistant exterior that endures UV exposure and temperature swings—boosting both durability and curb appeal.

High-Performance Coastal Windows

Upgrade to ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows installed by Alpine Siding Pros. Our precise measurements and advanced sealing methods eliminate drafts, reduce condensation, and improve thermal performance in Lummi Island’s maritime climate.

We evaluate existing frames and flashing before carefully removing old units, then perform a meticulous cleanup. Enjoy lower energy bills, superior soundproofing from island traffic, and unobstructed views of the Salish Sea and neighboring islands.

Custom Marine-Grade Decking

Extend your outdoor living with a bespoke deck from Alpine Siding Pros. We design and build decks using pressure-treated lumber, composite materials, or marine-grade hardwoods rated for salt-air and moisture. Our teams follow local code for joist spacing, ledger attachment, and proper drainage.

From simple viewing platforms to multi-level entertainment areas with corrosion-resistant fasteners and low-maintenance finishes, we deliver a safe, durable deck that enhances your Lummi Island home’s value and enjoyment year-round.

Why Alpine Siding Pros Excels on Lummi Island

Alpine Siding Pros combines 20 years of Pacific Northwest expertise with a deep understanding of Lummi Island’s marine-foothill climate and architectural styles. Our Bellingham-based team partners with Washington-state suppliers to source premium roofing, siding, window, and decking materials—ensuring rapid delivery and local support. We deliver transparent bids, manufacturer warranties, and community-focused service, guaranteeing every project is completed on time, on budget, and built to last.

Mastering the Building Envelope

We treat your home’s exterior as an integrated system—coordinating roofing, siding, windows, and decking to form a continuous barrier against moisture and air infiltration. Our crews install high-performance vapor barriers, marine-grade flashings, and premium sealants at every critical junction. By inspecting and reinforcing underlying sheathing and framing, we prevent rot and mold before they start, maximizing energy efficiency and indoor comfort in Lummi Island’s coastal environment.

Transparent Pricing & Courtesy Rot Repair

Integrity is our hallmark. At Alpine Siding Pros, rot repair is quoted separately as a courtesy—charged only if hidden decay is uncovered. Every estimate clearly line-items materials, labor, and any remediation so Lummi Island homeowners never face surprise fees. This transparency allows you to budget confidently and ensures your exterior project stays on schedule and on budget.

Local Partnerships & Island Community Focus

As a locally owned Bellingham contractor serving Lummi Island, we partner with Washington-state manufacturers and suppliers—supporting the regional economy and ensuring premium material access. Our crew lives in nearby communities, understands island permit processes, and respects local aesthetics. From minor repairs to major recladding, we communicate openly, adhere to timelines, and treat your property with care—building lasting relationships one home at a time.
