Building Materials and Brands We Supply

Impacco (Impac Company Inc.) supplies a full range of building materials for residential and commercial projects, from framing lumber and engineered wood to roofing, windows, doors, siding, insulation, and interior finishes. We source, consolidate, and ship complete orders from Seattle to Alaska, Hawaii, and Puget Sound job sites.

Because we are both a supplier and a freight specialist, you can order an entire project package from one company and have it loaded, protected, and shipped as a single coordinated order. Orders start at a $100 minimum.

Fasteners and General Supplies

We also supply fastening products and general jobsite supplies so your package arrives complete. On a remote site, one missing box of fasteners can stop a crew, so we help you build the full list before anything ships.

How Ordering Works

• Send your plans, takeoff, or materials list through our quote request form.
• We price the package and confirm the shipping method: full container, platform, LTL, LCL, or air cargo for urgent items.
• We consolidate the order, load it, and protect it for ocean transit with Alaska-wrap.
• Your materials ship to your port or community as one coordinated order.

Shipping Options

We handle full-container-load and platform shipments to Alaska and Hawaii, LTL and LCL shipments for freight between about 150 and 15,000 pounds, dock drop-off for LTL orders, and Alaska Air Cargo for last-minute needs. See our services for details.
