Classic suburban community with tree-lined streets and well-kept neighborhoods. Many 1960s-1980s homes offer great renovation potential. Homeowners are actively investing in kitchen remodels, basement finishing, and curb appeal improvements.
This is exactly why deck & patio construction in Mount Prospect requires a contractor who understands the community. At $325 000 median home value and housing stock from the 1950s-2000s era, the margin for error is small and the expectations are high.
Our licensed crew brings 15+ years of Northwest Suburbs experience to every deck & patio construction project. We've worked in Ranch and Bi-level homes throughout this area and understand the building codes, permit processes, and architectural nuances that define Mount Prospect.

Your Deck & Patio Project in Mount Prospect — Step by Step
From first call to final walkthrough — here's how we deliver deck & patio construction in Mount Prospect.
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 Northwest Suburbs Homeowners Say About Our Deck & Patio
“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.”
“Water damage from a roof leak left a big section of our ceiling wrecked. They cut out the damaged drywall, replaced it, mudded, sanded, and painted. Looks like nothing ever happened. Really impressed.”
“Gutters were overflowing during a winter thaw so I called CrestLine. They came out within a couple of days and cleared everything out. Downspouts draining perfectly now. Solid service.”
