Building Durable and Long Lasting Decks in Maryland

Decks serve as fantastic extended areas for entertaining guests, friends, and family members. Incorporating a deck into your home not only enhances its overall structure but also represents a smart investment that can significantly increase your property’s value. As a homeowner it is important to ensure that your deck is built using durable materials that can withstand weather and time.

We Build Decks that Lasts!

As your trusted deck contractor in Maryland, Alpha Design Services ensures that your deck is built using quality materials and adhering to industry-standard deck construction methods. As an organic material, decks that are made of traditional lumbers are vulnerable to mold, mildew and worse rotting! A healthy substructure is essential for the overall health of your deck and benefits you by:

1. Saving you on future maintenance/replacement costs.
2. Increasing the anticipated life of your deck.
3. Improving your deck’s structural integrity so you can enjoy your deck, worry-free, year after year.

Our team uses a unique and efficient taping technique that shields your deck’s substructure against the damaging effects of weather and moisture, resulting in an extended lifespan beyond the ordinary. A Deck Joist Flashing offers a cost-effective and efficient solution to mitigate potential problems arising from water penetration.

• Prevents moisture penetration of joists.
• Protects the lumber from rot.
• Extends the life of the deck’s substructure.

What Is Deck Joist Flashing Tape?

Deck Joist Flashing Tape is a water-resistant butyl adhesive used to keep moisture from penetrating your deck’s frame. While TimberTech composite deck boards are weather- and moisture-resistant, the traditional lumber used for the joists and ledger is susceptible to water damage.
