Your Deck & Patio Project in Buffalo Grove — Step by Step
From first call to final walkthrough — here's how we deliver deck & patio construction in Buffalo Grove.
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
“Replaced old carpet with luxury vinyl plank in the basement. Looks amazing and now I don't have to worry about moisture. Installation was clean and professional. Done in one day for about 600 sq ft.”
“Had about 800 sq ft of basement finished with a wet bar area and entertainment space. Good quality framing and finishing. A couple of punch list items at the end but they came back and addressed everything promptly.”
“Needed a new washer and dryer hookup in the second floor laundry. They ran the water lines, drain, and dryer vent. Good work overall, and they tested everything thoroughly before leaving.”
