Frequently Asked Questions

We understand that planning a deck renovation or extension raises questions. Here are answers to some of the most common things homeowners ask before getting started.

Question 1: How do I know if my deck can be re-decked instead of rebuilt?

If your deck’s foundation and framing are still solid, re-decking is a great option. We’ll inspect your structure to make sure it meets current safety standards before replacing the surface boards with durable new materials.

Question 2: What materials do you use for re-decking or extensions?

We offer both composite decking (like Trex® and TimberTech®) and premium natural woods such as cedar or pressure-treated lumber. Our team will help you choose the best option for your style, budget, and maintenance preferences.

Question 3: How long does a typical deck extension or re-decking project take?

Most projects can be completed within a few days to two weeks, depending on size, complexity, and material choice. We’ll provide a clear timeline during your free estimate so you know exactly what to expect.

Question 4: Will my new deck match the rest of my home?

Absolutely. Our designers specialize in creating seamless transitions that blend your new or upgraded deck with your home’s architecture and landscape for a cohesive look.
