Our Services

Mountain-Ready Roofing Solutions in Custer

Alpine Siding Pros installs premium asphalt shingle and standing-seam metal roofs engineered for Custer’s heavy snow loads and seasonal rains. Our certified installers perform thorough deck inspections, apply high-performance underlayment, and seal all flashings to prevent leaks and ice dams.

We begin each project with a detailed structural assessment to uncover any hidden rot or deck damage—offering courtesy rot repair at a nominal fee. Backed by manufacturer warranties and our commitment to on-time completion, your new roof will protect your Custer home and maintain its curb appeal for decades.

Durable Siding Installations in Custer

Enhance your Custer residence with low-maintenance vinyl, fiber cement, or engineered wood siding. Our crews align trim with laser precision, install continuous waterproofing membranes, and caulk every joint to block moisture and drafts in the mountain climate.

Each siding project starts with substrate evaluation and sheathing inspection. By combining premium materials with perfected water-barrier techniques, we deliver an energy-efficient, mold-resistant exterior that endures UV exposure and temperature swings—boosting both durability and aesthetic appeal.

High-Performance Windows for Custer 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 Custer’s variable weather.

We assess existing frames and flashing before carefully removing old units, then perform a meticulous cleanup. Enjoy lower utility bills, superior soundproofing from mountain winds, and panoramic views of the North Cascades from every room.

Custom Decking Solutions in Custer

Transform your outdoor living with a custom deck from Alpine Siding Pros. We design and build decks using pressure-treated lumber, composite materials, or hardwoods rated for moisture resistance. Our installers adhere to local code for joist spacing, ledger attachment, and proper drainage.

From simple platform decks to multi-tier entertaining areas, we select corrosion-resistant fasteners and low-maintenance finishes. The result is a safe, durable deck that enhances your Custer home’s value and enjoyment year-round.

Why Alpine Siding Pros Excels in Custer

Alpine Siding Pros combines two decades of mountain-region expertise with a deep understanding of Custer’s rugged climate and alpine 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 deliver 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 form a seamless barrier against moisture and air infiltration. Our crews install high-quality vapor barriers, durable flashings, and premium sealants at all critical junctions. By inspecting and repairing underlying sheathing and framing, we prevent rot and mold before they start and maximize energy efficiency and indoor comfort.

Transparent Pricing and Rot Repair

Hidden costs erode trust. At Alpine Siding Pros, we separate rot repair from core services—charging only a small courtesy fee when replacing damaged sheathing or framing. Every bid clearly itemizes materials, labor, and any rot remediation so Custer homeowners never face surprise invoices. This transparency allows you to budget confidently and focus on the quality of your exterior improvements.

Local Partnerships and Community Commitment

As a locally owned Bellingham contractor, we partner with Washington-based manufacturers and suppliers—supporting the regional economy while securing premium materials for your Custer project. Our team lives in the communities we serve, understands local building codes, and respects neighborhood character. Whether handling a small repair or a major recladding project, we communicate openly, adhere to schedules, and treat your property with care—building lasting relationships one project at a time.
