Our Services

Marine-Grade Roofing Solutions in Lummi

Alpine Siding Pros installs asphalt shingle and standing-seam metal roofs formulated to resist Lummi’s salt-laden air, heavy rains, and occasional snow. Our certified crews conduct a full deck inspection, apply marine-rated underlayment, and seal all flashings with premium sealants to prevent leaks and ice dams.

Every roofing project begins with a structural assessment to uncover hidden rot or framing damage—courtesy rot repair is available at a nominal fee. Backed by manufacturer warranties and our commitment to punctual completion, your new roof will protect your home and enhance curb appeal for decades.

Coastal-Ready Siding Installations in Lummi

Enhance your Lummi home with low-maintenance vinyl, fiber cement, or engineered wood siding. Our installers align trim to millimeter precision, install continuous waterproofing membranes, and caulk every seam to block moisture, drafts, and salt intrusion in the maritime environment.

Each project starts with a thorough substrate and sheathing inspection. By pairing premium materials with our perfected water-barrier techniques, we deliver an energy-efficient, mold-resistant exterior that endures UV exposure and temperature swings—boosting both longevity and seaside charm.

High-Performance Windows for Lummi Homes

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’s variable coastal climate.

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

Custom Marine-Grade Decking in Lummi

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 coastal moisture and sun exposure. Our crews adhere to local code for proper joist spacing, ledger attachment, and drainage.

From simple viewing platforms to multi-level entertainment decks with cable railings, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that maximizes your Lummi home’s waterfront lifestyle.

Why Alpine Siding Pros Excels in Lummi

Alpine Siding Pros combines 20 years of Pacific Northwest exterior contracting expertise with deep knowledge of Lummi’s marine-foothill environment. Our Bellingham-based team partners with Washington suppliers to source premium roofing, siding, window, and decking materials—ensuring rapid delivery and local support. We provide 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 view your home’s exterior as a single 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 all critical junctions. By inspecting and reinforcing underlying sheathing and framing, we prevent rot and mold before they start, maximizing energy efficiency and long-term durability.

Transparent Pricing & Courtesy Rot Repair

Honesty is our foundation. At Alpine Siding Pros, rot repair is quoted separately as a courtesy—charged only when hidden decay is uncovered. Every estimate line-items materials, labor, and any remediation so Lummi homeowners never face surprise fees. This transparency lets you budget confidently and ensures your exterior project stays on schedule, on budget, and free of hidden costs.

Local Partnerships & Island Community Focus

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