Frequently Asked Questions

How do I know which deck service I need?

The right service depends on the condition of your existing deck and what you want to accomplish. We evaluate the structure or building site first and determine whether repair, replacement, new construction, or a specialty service is the appropriate starting point.

What's the difference between deck repair and deck replacement?

Deck repair addresses localized problems while preserving structurally sound portions of the existing deck. Replacement is generally appropriate when deterioration affects the framing, footings, posts, beams, or other major structural components.

Can you replace only the decking?

Yes, when the underlying framing is structurally sound and suitable for the new decking system. We evaluate the existing structure before recommending resurfacing rather than a full replacement.

Can you expand an existing deck?

Yes. Deck expansions can add space for dining, entertaining, stairs, a hot tub, or improved access to the backyard. Depending on the design, new footings, framing, railings, and permits may be required.

What decking materials do you install?

Petra Decks installs composite, PVC, and cedar decking. Material selection depends on appearance, maintenance expectations, exposure conditions, budget, and the overall deck design.

Which areas do you serve?

Petra Decks serves homeowners throughout King County, including Maple Valley, Kent, Auburn, Renton, Sammamish, Issaquah, Snoqualmie, North Bend, Black Diamond, Covington, Newcastle, Bellevue, Redmond, Mercer Island, and nearby communities.
