Our White-Glove Deck & Patio Process for Wilmette Homeowners
From first call to final walkthrough — here's how we deliver deck & patio construction in Wilmette.
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
“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.”
“CrestLine completely transformed our outdated 1990s kitchen. New shaker cabinets, quartz countertops, and a stunning tile backsplash. The crew was meticulous about protecting our floors and cleaned up every single day. Couldn't be happier with the result.”
“I had a whole list of small jobs that had been bugging me for months — squeaky doors, a loose railing, caulking in the bathroom, and a shelf that needed mounting. CrestLine knocked them all out in one visit. So nice to have everything done!”
