Our Services

Skagit-Ready Roofing Solutions in Mt. Vernon

Alpine Siding Pros installs premium asphalt shingles and standing-seam metal roofs built for Mt. Vernon’s heavy rains and river-valley winds. Our certified crews begin with a thorough deck inspection, apply high-performance underlayment, and seal all flashings with corrosion-resistant sealants to prevent leaks, ice dams, and wind-driven moisture.

We perform 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 on-time completion guarantee, your new roof will protect your home and boost curb appeal for decades.

Precision Siding Installations for Skagit-Valley Homes

Refresh your Mt. Vernon façade with low-maintenance vinyl, fiber cement, or engineered wood siding. Our installers achieve laser-accurate trim alignment, install continuous waterproofing membranes, and caulk every seam to block moisture, drafts, and pests in the local climate.

Starting with substrate and sheathing inspection, we pair top-tier materials with perfected moisture-barrier techniques. The result is an energy-efficient, mold-resistant exterior that endures UV exposure and temperature swings—elevating both durability and visual appeal.

Energy-Efficient Windows with Scenic Views

Alpine Siding Pros installs ENERGY STAR®-rated double- and triple-pane vinyl or fiberglass windows designed for Mt. Vernon’s variable weather. Our precise measurements and advanced sealing methods eliminate drafts, reduce condensation, and enhance thermal performance year-round.

We evaluate existing frames and flashing before carefully removing old units, then conduct a meticulous cleanup. Enjoy lower utility bills, superior soundproofing from valley traffic, and unobstructed views of the Skagit River and surrounding foothills.

Custom Decks Overlooking the Skagit

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 moisture resistance. Our crews follow local code for proper joist spacing, ledger attachment, and drainage.

From simple riverside platforms to multi-level entertainment decks, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that enhances your Mt. Vernon home’s value and provides years of outdoor enjoyment.

Why Alpine Siding Pros Excels in Mt. Vernon

Alpine Siding Pros combines 20 years of Pacific Northwest exterior-contracting expertise with deep knowledge of Mt. Vernon’s river-valley climate and historic neighborhoods. Our Bellingham-based team partners with Washington suppliers to source premium roofing, siding, windows, and decking materials—ensuring rapid delivery and local support. We deliver transparent bids, manufacturer-backed warranties, and community-focused service, guaranteeing every project is on time, on budget, and built to last.

Mastering the Building Envelope

We treat your home’s exterior as a unified system—coordinating roofing, siding, windows, and decking to form a seamless barrier against moisture and air infiltration. Our crews install high-performance vapor barriers, precision flashings, and premium sealants at all 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 if hidden decay is uncovered. Every estimate line-items materials, labor, and any remediation so Mt. Vernon homeowners never face surprise fees. This transparency lets you budget confidently and ensures your exterior project stays on schedule and on budget.

Local Partnerships & Community Commitment

As a locally owned Bellingham contractor serving Mt. Vernon, we partner with Washington-state manufacturers and suppliers—supporting regional businesses while securing premium materials. Our crew lives in the communities we serve, understands local codes and permit processes, and respects neighborhood character. 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.
