Deck & Patio Construction in Chicagoland
Chicagoland homeowners enjoy roughly five to six months of outdoor weather each year, and a well-designed deck or patio transforms that time into daily living space. Whether you envision a multi-level composite deck off the kitchen for summer grilling, a ground-level paver patio with a fire pit, or a shaded pergola retreat with outdoor lighting, CrestLine Home Pro designs and builds outdoor spaces that withstand harsh Midwest winters while looking beautiful year after year.
Material selection is critical in our climate. We are factory-certified installers of Trex, TimberTech, and Azek composite decking — products engineered to resist freeze-thaw cycling, UV fading, and moisture absorption without annual staining or sealing. For patio projects we work with Unilock, Belgard, and Techo-Bloc pavers that carry lifetime structural warranties and offer hundreds of color, texture, and pattern options from modern linear designs to classic herringbone.
Every deck project starts with a structural engineering review. We verify ledger-board connections, footing depths below the frost line (42 inches in northern Illinois), and beam spans to meet or exceed IRC code requirements. Railings, stair systems, and lighting are integrated during the design phase — not added as afterthoughts — so the final result is cohesive and code-compliant.
From a simple 200-square-foot deck replacement to a resort-style outdoor living package with a pergola, built-in seating, an outdoor kitchen island, and low-voltage landscape lighting, we handle design, permitting, construction, and final inspection as a single turnkey team.

The CrestLine Advantage
How Deck & Patio Works
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.

Deck & Patio FAQ
What Our Clients 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.
Had an old rotting wood deck torn down and a new Trex deck installed. Also added a pergola. The craftsmanship is solid and it looks fantastic. Great for entertaining this summer.
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.
