Our Deck Modification Services

At Synapse Construction, we believe every deck should reflect the homeowner’s style and needs. That’s why we start every deck modification project with a personalized consultation. We’ll take the time to understand how you use your deck, what improvements you’d like to make, and what materials or styles appeal to you. From there, we’ll create a custom plan that aligns with your goals. Our most requested deck modification services include:

  • Deck waterproofing – Clyde Hill’s rainy climate makes deck waterproofing a smart investment. We use proven systems and materials to protect your wood deck from moisture, mold, and decay. With the proper waterproofing in place, your deck will look better and last longer, no matter the weather.
  • Deck expansions – If your current deck feels too small or limited, we can expand it to create a more functional and inviting space. Whether you want to add a dining area, a built-in bench, or just more room for entertaining friends and family, we’ll design a layout that works with your home and landscape. The result is a deck that feels like a natural extension of your living space.
  • Deck upgrades – Need to improve your deck’s safety, style, or usability? We offer a variety of upgrades, including new railings, steps, integrated lighting, and updated decking materials. We’ll help you replace worn components and add features that make your deck more enjoyable and easier to maintain.
