Deck Repairs & Upgrades

Time, weather, and daily use take their toll on even the best-built decks. At King County Decks, we believe a worn or outdated deck shouldn’t mean starting from scratch. Whether your structure needs a few key repairs or a full-scale upgrade, we restore, reinforce, and reimagine your outdoor space with craftsmanship that lasts.

Our team brings over 23 years of construction expertise from our roots in MJK Construction — a trusted name in residential building across Oregon and Washington. That same reputation for quality now defines every deck restoration we take on, from basic fixes to complete transformations.

Every Repair Done Right

We handle everything from loose boards and rotting joists to unsafe stairs, damaged railings, and structural issues that need serious attention. Our process begins with a thorough inspection and honest assessment of your deck’s condition, followed by a clear plan for how we can bring it back to life — stronger and better than before.

Upgrades That Add Value

Looking to take your outdoor space to the next level? We offer modern upgrade solutions to match your lifestyle, design taste, and budget. Whether it’s replacing worn wood with composite materials, adding custom railings, expanding your layout, or installing lighting for night-time ambience, we tailor each upgrade to your vision.

From simple backyard patios perfect for family barbecues to fully customized, multi-level decks with pools, jacuzzis, and built-in seating — no project is too small or too complex. We manage everything, including design, materials, permitting, and construction.

Honest Estimates. Lasting Results.

Our quoting process is simple and transparent. You’ll receive a detailed estimate with clear scope, pricing, and timeline — no hidden fees or vague allowances. We work with both cost-effective and luxury materials, helping you choose what fits best without sacrificing quality.

Proudly serving Bellevue, Seattle, Tacoma, Kirkland, Redmond, Mercer Island, and surrounding areas — King County Decks is your trusted partner in restoring and upgrading outdoor spaces with integrity and precision.
