Considering Deck Renovation Instead of Full Replacement?
If your deck structure is still sound but the surface materials or layout need improvement, renovation may be a practical option.
We offer selective upgrades including new decking, railing replacement, and layout adjustments—focused on extending the life of your existing structure where possible.
However, if underlying framing, footings, or support elements are compromised, renovation won’t solve the issue. In those cases, full deck construction and replacement is the safer long-term approach.

Deck Construction FAQs
How do I know if I need deck construction or renovation?
If the structure is still sound, renovation may be an option. If framing, footings, or support posts are failing, full deck construction and replacement is usually the safer long-term solution.
What does deck construction include?
Deck construction includes full structural framing, footings, support posts, stairs, and layout design. Projects are built from the ground up or replaced entirely when existing structures are no longer safe.
When is deck renovation a good option?
Renovation is a good option when the structure is still in good condition and only surface materials or layout need updating. This can include replacing decking boards, upgrading railings, or improving usability.
What materials work best for decks in Washington?
Composite and PVC decking perform best in wet climates due to moisture resistance and low maintenance. Cedar is also used but requires ongoing upkeep.
How long does deck construction take?
Most deck construction projects take one to three weeks depending on size, complexity, and site conditions such as slope or access.
Do you build decks on sloped or uneven properties?
Yes. Many homes in King County require decks designed for slope, elevation, and drainage. Proper structural planning is critical for long-term performance.
