Deck & Patio Construction

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.
