The team was professional, punctual, and incredibly knowledgeable. They took the time to answer all of my questions, communicated clearly throughout the project, and paid close attention to every detail. The quality of their workmanship exceeded my expectations, and the finished deck looks absolutely amazing. They treated my home with respect, kept the work area clean, and completed everything on schedule. It’s rare to find a company that truly delivers on its promises, but Sidex Siding & Decking did exactly that.

Common Questions from Lafayette Homeowners
Can you build on a steep slope?
Absolutely. Many Lafayette homes are on hillsides. We specialize in engineering curved deck lafayette designs and multi-level structures that are properly anchored and earthquake-safe.
Do I need a permit for a new deck?
Yes, most decks require a permit. We handle the entire permitting process with the City of Lafayette or Contra Costa County, so you don’t have to worry about paperwork or codes.
What is the best material for a pool deck?
We often recommend PVC or specific composite lines for pool deck installation projects because they are slip-resistant and don’t absorb water, preventing mold and rot near the splash zone.
