Hawaii Deck Builders: Frequently Asked Questions
Are you licensed deck builders in Hawaii?
Yes — Hawaii Deck Builders is a division of Hilweh Builders LLC which is a licensed, bonded, and insured contractor (BC-37232) specializing in custom decks, railings, and outdoor living spaces across Oahu. We are also a TrexPro certified installer and a NADRA Deck Safety Specialist.
What areas of Oahu do you serve?
We typically work in Kaneohe, Kailua, Honolulu, Hawaii Kai, and the greater Honolulu area — but we often find ourselves building in all parts of the island. The best way to work with us is to reach out for a free consultation so we can discuss your project and location.
What materials do you use for decks?
We work with premium wood and composite decking, including Ipe, TimberTech, Trex, Fiberon, Feeney and Wolf products. Our team helps you choose the best option for Hawaii’s climate — balancing beauty, durability, and maintenance.
Do you provide warranties on your work?
Yes — we stand behind our craftsmanship with a workmanship warranty, and because we are certified installers with partner brands like Trex and TimberTech, we can also offer exclusive extended manufacturer warranties that other contractors cannot. This ensures you get both quality construction and long-term protection for your investment.
Here is an example, let's say you replace your deck with Trex Transcend deck boards, Trex Signature railing and Trex fasteners. You will receive:
- 1 Year workmanship warranty from Hawaii Deck Builders.
- 8 Year Trex labor warranty (because we are a Trex Pro Gold certified installer).
- 50 Year fade & stain warranty on Trex Transcend decking.
- 25 Year warranty on Trex Signature railing.
Decks are a large investment, ensure your investment is covered by working with a certified deck pro like Hawaii Deck Builders.
How do I know if my deck needs a full replacement or just repairs?
We’ll begin with a thorough inspection of your deck’s structure — checking joists, posts, beams, footings, and boards. If issues are limited to surface problems (such as rotting boards, loose railings, or small damaged sections), repairs may be enough. But if the substructure is compromised (rotted or weakening beams/posts, unstable footings, sagging, or safety issues), a full replacement is usually safer and more cost-effective in the long run.

How much does it cost to build or replace a deck in Oahu?
Costs depend heavily on size, materials, layout complexity, and whether you need features like stairs, railings, or custom designs. The cost of your project will also vary based on accessibility and the level of replacement needed — for example, whether you are building a new ground-level deck or replacing a second-story deck with structural upgrades. Material choice is also a key factor, as the cost of deck boards and railings can vary significantly from project to project.
In general, homeowners in Hawaii can expect a broad range from $15,000 to $150,000+ depending on scope and materials. For a detailed breakdown with real-world examples, visit our Hilweh Builders Deck Cost Guide.
