Deck Construction & Repair in Cupertino, CA | Castillo Fence & Deck

Cupertino’s hot summers can cause wood decks to warp or crack. We recommend composite or PVC decking for low maintenance and heat resistance. If you prefer wood, we use pressure-treated lumber or cedar with proper sealing to minimize warping. We’ll help you choose based on your budget, style, and how much upkeep you’re comfortable with.

We install decks with correct spacing between boards to allow for expansion, use moisture barriers underneath, and apply a high-quality sealant or stain. For existing decks showing signs of warping, we can repair or replace affected boards. In many cases, switching to composite during a replacement eliminates future warping issues entirely.

If your deck has extensive rot, loose connections, or is over 20 years old, replacement is often more cost-effective and safer. We provide free inspections to assess structural integrity. Repair works for isolated damage like a few rotten boards, but widespread issues usually call for a full replacement to meet current building codes and ensure longevity.
