Landmark Building Supply helps Hawaii homeowners customize with durable, high-quality aluminum products

HONOLULU (HI Now) - As more Hawai‘i homeowners invest in home improvements that blend modern design with local durability, Landmark Building Supply has emerged as a trusted source for customizable, weather-resistant building materials tailored for island living.

Founded and based in Honolulu, Landmark Building Supply specializes in high-performance aluminum windows and doors, custom staircases and railings, sleek garage doors, walk-in closets, and secure gates and fences. The company serves both homeowners and industry professionals across O‘ahu and neighboring islands.

Custom Materials Built for Island Conditions

With Hawai‘i’s high humidity, coastal salt exposure, and year-round sun, building materials need to be both beautiful and built to last. Landmark offers aluminum products with thermal breaks, Low‑E glass, and advanced coatings that meet energy efficiency and corrosion resistance standards.

Customers can choose from a wide range of finish options, hardware styles, and configurations, with the ability to fully customize products to fit their space and design preferences. Landmark also provides 3D renderings and personalized consultation services to ensure a seamless design-to-installation process.

Manufacturer-Direct Pricing and Local Support

What sets Landmark apart is its direct-from-manufacturer pricing model. By eliminating middlemen, the company offers luxury materials at competitive rates while maintaining high standards of craftsmanship and performance. Clients can purchase materials alone or take advantage of Landmark’s full-service options, including shipping coordination, project management, and installation support.

Their Honolulu showroom, located at 905 Umi Street, features a curated design studio where visitors can view samples, discuss their goals with product specialists, and explore ideas through interactive design tools.

Locally Owned and Community Trusted

Since opening its doors in 2020, Landmark has built a strong reputation for customer service, product knowledge, and project reliability. The company is locally owned and operated, with a growing presence in both residential and commercial markets.
