Frequently Asked Questions
How do I know which deck service I need?
The right solution depends on your deck's condition and your long-term goals. Whether you're planning a new deck, replacing an aging structure, repairing damaged components, or adding specialty features, we'll evaluate your project and recommend the safest and most cost-effective approach.
What's the difference between deck repair and deck replacement?
Deck repair addresses localized issues such as damaged decking, stairs, railings, or framing while preserving the existing structure whenever possible. Complete deck replacement is recommended when the framing, footings, or support system have deteriorated or no longer meet current building standards.
Can you expand my existing deck?
Yes. If you'd like more outdoor living space, we can design and build a custom deck expansion. Many expansion projects require new footings, framing, stairs, and railings to create a seamless addition that looks and performs like it was always part of your home.
Do you build covered and multi-level decks?
Yes. Petra Decks designs and builds custom covered decks, multi-level decks, hot tub decks, and other specialty outdoor living projects tailored to your home, property, and lifestyle.
What decking materials do you install?
We install premium composite, PVC, and cedar decking from trusted manufacturers. We'll help you compare colors, maintenance requirements, durability, and budget to choose the material that's right for your home.
Which areas do you serve?
Petra Decks proudly 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 surrounding communities.
Do you provide on-site consultations?
Yes. Every project begins with an on-site consultation where we discuss your goals, evaluate the existing structure or building site, answer your questions, and recommend the best solution for your home and budget.
Do I need a permit to build or replace a deck?
Most new deck construction, structural replacements, and deck expansions require permits. Petra Decks builds decks to current Washington building codes.
