Our Services

Coastal-Grade Roofing in La Conner

Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs built to resist La Conner’s salt-laden air, heavy rains, and wind. Our certified team performs a comprehensive deck inspection, applies industrial-strength underlayment, and seals all flashings with marine-grade sealants to prevent leaks and ice dams.

Prior to installation, we conduct a full structural evaluation—identifying any hidden rot or deck damage—and include courtesy rot repair at a nominal fee. Backed by manufacturer warranties and our on-time completion guarantee, your new roof will protect your home and enhance its maritime curb appeal for years.

Durable Siding Installations in La Conner

Upgrade your La Conner home’s exterior with low-maintenance vinyl, fiber cement, or engineered wood siding. Our experts align trim with laser precision, install continuous moisture barriers, and caulk all seams to block drafts, moisture, and pests in the coastal climate.

Each siding project begins with substrate and sheathing inspection. By pairing premium materials with our perfected waterproofing techniques, we deliver an energy-efficient, mold-resistant façade that endures UV exposure and temperature swings—boosting longevity and enhancing your home’s historic waterfront charm.

Energy-Efficient Window Replacements

Alpine Siding Pros installs ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows designed for La Conner’s variable temperatures. We take meticulous measurements and employ advanced sealing to eliminate drafts, reduce condensation, and maximize thermal comfort in all seasons.

We inspect existing frames and flashing before carefully removing old units, then complete a thorough cleanup. Enjoy lower energy bills, superior soundproofing from harbor traffic, and panoramic views of Swinomish Channel and nearby mountains.

Custom Deck Construction in La Conner

Transform your outdoor living with a bespoke deck from Alpine Siding Pros. We build using pressure-treated lumber, composite materials, or marine-grade hardwoods rated for coastal moisture and sun exposure. Our crews adhere to local code for joist spacing, ledger attachment, and proper drainage.

From simple waterfront platforms to multi-level entertainment decks with cable railings, we choose corrosion-resistant fasteners and low-maintenance finishes—creating a safe, durable deck that enhances your La Conner property value and seaside lifestyle.

Why Alpine Siding Pros Excels in La Conner

Alpine Siding Pros combines 20 years of Pacific Northwest exterior contracting expertise with a deep understanding of La Conner’s coastal-foothill environment and heritage architecture. 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-backed 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 work in unison against moisture and air infiltration. Our crews install high-performance vapor barriers, precision flashings, and premium sealants at critical junctions. By inspecting and reinforcing underlying sheathing and framing, we prevent leaks and rot before they start, maximizing energy efficiency and indoor comfort.

Transparent Pricing & Courtesy Rot Repair

Honesty is our hallmark. At Alpine Siding Pros, rot repair is quoted separately as a courtesy service—charged only upon discovery of damaged sheathing or framing. Every estimate line-items materials, labor, and any remediation so La Conner homeowners never face surprise fees. This transparency allows you to budget confidently and keeps your project on schedule and on budget.
