Protecting Your Investment

Decks and patios are a significant investment and proper flashing helps to protect that investment by creating a barrier between the concrete and wood elements. Without flashing, the joint between the concrete and wood can become vulnerable to various elements such as water, snow, ice, and even pests. With flashing in place, the joint is protected, and it can increase the lifespan of the structure and prevent costly repairs.

Enhancing the Durability

Flashing not only helps to protect the joint, but it can also enhance the overall durability of the deck or patio. It can prevent warping, cracking, or shifting of the materials, and also prevent the growth of mold, mildew, or pests that can weaken the structure over time. With flashing in place, the structure is more stable and able to withstand the elements better.

Improving the Aesthetics

Flashing not only serves a functional purpose but also improves the overall aesthetics of a deck or patio. Proper flashing installation can be tailored to match the design and color of the structure, giving it a clean and polished look. It can also be used to create an interesting design element that can make the structure stand out.
