Is your deck showing signs of water damage, rot, or mildew? Living in Baltimore means enjoying plenty of sunny days on your deck—but also dealing with unpredictable weather, humidity, and rainfall that can quickly take a toll on your outdoor space. If you want to keep your deck looking beautiful and safe for years, deck waterproofing services are a must.

At D & I Contractors, we specialize in providing top-rated deck waterproofing solutions and expert deck building services for homeowners across Baltimore and surrounding areas. Whether you need to waterproof an old deck, install a new one, or repair damage caused by years of exposure, we have the tools, expertise, and local experience to get the job done right.

Why Deck Waterproofing Matters in Baltimore

Baltimore’s unique climate—with its heavy rains, seasonal storms, and humid summers—can cause wood and composite decks to deteriorate faster than you think. Moisture is the #1 enemy of your deck, leading to:

  • Wood rot, soft spots, and structural weakness

  • Mold and mildew growth (not just unsightly, but unsafe)

  • Warped, cracked, or splintering boards

  • Costly repairs or even total replacement

A professionally waterproofed deck resists these issues, adds years to your deck’s life, and keeps your family safe.

Types of Deck Waterproofing Solutions We Offer

Not all decks or situations are the same, so D & I Contractors provides a variety of waterproofing options:

  • Liquid waterproof coatings: Flexible, durable, and ideal for most wood decks.

  • Membrane systems: Sheet or roll-on membranes for extra protection, especially over living spaces.

  • Under-deck drainage systems: Keeps the area below your deck dry—perfect for elevated decks or patios.

  • Waterproof deck tiles/overlays: Stylish and functional upgrade options.

Not sure which is best for your home? We’ll inspect your deck and recommend the right solution for your needs and budget.

Frequently Asked Questions About Deck Waterproofing

How long does deck waterproofing last? Quality systems last 3–7 years before needing reapplication.

How often should I waterproof my deck? We recommend every 2–3 years, depending on exposure.

Can all decks be waterproofed? Most can! We’ll advise if your structure is suitable.

What’s the difference between sealing and waterproofing? Sealants protect the surface, while waterproofing creates a barrier against moisture penetration.
