Our Process
Free Site Walk-through & Prep Inspection
We’ll visit your property across our service areas, inspect your deck for water damage, warping, or structural issues, take full measurements, plan material access and debris removal, check for obstructions and identify any underground utility risks. We also review railing stability, surface safety, and overall project feasibility to ensure the repair or replacement process is smooth, secure, and fully aligned with safety standards and local building codes.
Prep, Repair & Material Selection
We select the correct waterproofing, caulking, stain, or paint system based on your deck’s condition and material type. Our team repairs damaged boards or fasteners, addresses loose connections, fills gaps, and eliminates surface imperfections. We then clean, sand, and fully prepare the deck for a flawless, long-lasting finish. This ensures enhanced durability, stronger protection against weather, improved safety, and a beautiful final appearance that restores and preserves the entire outdoor structure.
