Our White-Glove Deck & Patio Process for Winnetka Homeowners
From first call to final walkthrough — here's how we deliver deck & patio construction in Winnetka.
Site Evaluation & Design
We assess your yard grade, sun exposure, access points, and utility locations. Together we design the layout, select materials, and finalize features like railings, lighting, and built-ins.
Permitting
We prepare drawings, submit to your municipality, and obtain the building permit. Most suburbs require permits for any attached deck or paver area over a certain size.
Foundation & Framing
Footings are excavated below the frost line, posts are set in concrete, and the structural frame — beams, joists, ledger board — is built to code specifications.
Decking, Railings & Features
Deck boards, railing systems, stairs, and any custom features like pergolas, benches, or lighting are installed. Paver patios receive gravel base, sand leveling, and edge restraints.
Final Inspection & Handoff
We schedule the municipal inspection, walk you through care and maintenance, and ensure every detail meets our standards before the project is complete.

What North Shore Homeowners Say About Our Deck & Patio
“Brand new composite deck off the back of our house, about 400 sq ft with built-in benches and planters. The design is exactly what we envisioned. Survived its first winter with zero issues. CrestLine does top-notch outdoor work.”
“CrestLine built a paver patio with a fire pit area in our backyard. Drainage is good and the pattern looks professional. We can't wait to use it once the weather warms up. Minor delay due to weather but that's understandable.”
“Our master bathroom went from cramped and dated to a spa-like retreat. Walk-in shower with frameless glass, heated floors, double vanity — everything we wanted. CrestLine's attention to detail on the tile work was incredible.”
