We LOVE our deck and patio! Still doesn't feel really ours because it looks like at a nice resort. From the very first estimate, I knew which company I would be hiring. If you want confidence knowing that its built right, I highly recommend David at Legacy as an expert project designer!

David and his team are masters at their craft, as their final products show. Add in excellent communication and a willingness to work around unusual schedule requests, there's simply no need to look elsewhere for your upcoming deck/porch project. Our family loves our new deck, and cannot recommend Legacy enough.

Frequently Asked Questions

With clear answers to most homeowners deck-related questions:

How much does a typical deck cost in Seattle?

Most of the projects we build in Seattle fall between $50,000–$80,000.
Smaller, simpler decks start around $40,000–$50,000, while large multi‑level or “outdoor living room” builds with railings, lighting, and stairs can be $80,000+.

After a quick call and a few photos, we’ll give you a clear ballpark range before anyone comes to your home, so you can see if it fits your budget with zero pressure.

What's the difference between wood and composite?

In simple terms: wood costs less upfront, composite costs less over time.

- Wood (pressure‑treated or cedar): lower initial price, needs staining/sealing every 12-18 months, typically lasts 15-30 years with good care.

Composite: higher upfront, no staining or sealing, resists warping and rot, and can last 50+ years with basic cleaning.

During your consultation, we’ll show you good / better / best options so you can see how the look, maintenance, and price compare.

What does the process look like from first call to finished deck?

Our job is to make this simple:

1. Phone / virtual consult to talk through your ideas, budget, and timeline.

2. On‑site visit & measurements so we can design to your exact space.

3. Design & proposal with a clear scope, price, and options.

4. Permits & HOA approvals handled by our team.

5. Build phase where our crew completes the project and keeps your yard tidy.

6. Final walkthrough to make sure everything looks and functions exactly how you expected.


Most projects move from first call to completed deck in about 8-12 weeks, depending on design and permits.

How long does it take to get permits and start building?

In Seattle, permits typically take about 5-10 weeks once plans are submitted. Some projects are faster, more complex designs can take a bit longer.

We handle all drawings, paperwork, and back‑and‑forth with the city/HOA for you, and we keep you updated so you’re never wondering where things stand. Once permits are approved, we schedule your start date and lock it in.

Are you licensed, insured, and familiar with local building codes?

Yes. Legacy Decking is a fully licensed and insured contractor in Washington.

License: #LEGACDL775QP

Coverage: $1,000,000 Liability Coverage

We pull all required permits, build to building codes, and coordinate inspections so your deck is safe, legal, and ready to enjoy.

Do you offer financing or payment plans?

Yes. For qualified homeowners, we offer financing through our trusted partners so you can pay for your deck over time instead of in one lump sum.

Ask us during your consult and we’ll walk you through the options for your exact project amount.

What kind of warranty do you offer on workmanship and materials?

You get Lifetime workmanship coverage from Legacy Decking. If something we built fails due to our installation during that time, we fix it at no labor cost to you.

On top of that, many of the composite and railing products we use carry manufacturer warranties of 25–50 years against fading, staining, and structural defects.

What happens if something goes wrong or I'm not happy after the project?

If something isn’t right, we make it right.

Here’s how we handle it:

  1. You let us know what’s wrong.
  2. We schedule a visit to inspect and diagnose the issue.
    If it’s related to our workmanship, we fix it at no labor cost.
  3. If it’s a material issue, we help you work directly with the manufacturer to use your product warranty.

We also offer a Lifetime Warranty on our projects!

What happens after I fill out the form?

You’ll hear from us within 30-60 minutes during business hours (or first thing the next business day).

  1. We’ll confirm a few details about your project and answer initial questions.
  2. We’ll ask for photos of your existing space so we can come prepared.
  3. We’ll schedule a phone or in‑home consultation at a time that works for you.

No spam, no endless sales calls – just a clear plan, a price range, and next steps so you can decide if we’re the right fit.
