Deck Cost Context
New construction or replacement: price the right Mundelein scope
Composite deck addition
$25,096What changes the number in Mundelein?
Public sources do not publish a reliable true average deck cost for Mundelein alone. Actual project cost depends on size, deck height, material, demolition, stairs, railing, lighting, access, existing structure, grade, drainage, mature trees, privacy, permitting, and what is found during the site walk-through.
The benchmark above comes from the 2025 Cost vs. Value report and should be used for planning conversation only. MRBCC can give a more useful number after seeing the home and understanding the project.
Why Mundelein Homeowners Call MRBCC
Different starting points around Diamond Lake and the village
Mundelein's Diamond Lake setting, established streets, and newer residential projects mean deck planning starts from different conditions. One home may need an aging structure assessed; another may need a first connection from an elevated rear door to the lawn. We establish that starting point before discussing finishes.
The Heritage Museum is a reminder of the village's changing built environment. At your home, the useful question is what to retain and what to improve. Existing stairs, patios, garden paths, and door heights help determine whether resurfacing, a replacement footprint, or a new design is the better conversation.
Your Project Options
From first-time decks to complete structural replacements
For a Mundelein rebuild, a clear condition review helps distinguish boards that need replacement from a frame that needs more extensive work. Keep those scopes separate when comparing cedar and composite proposals.

Most occupied homes in Mundelein are owner-occupied.
These published estimates describe the community, not an individual property. Household income and home values do not determine your quote. Deck dimensions, materials, access, and existing conditions do.
Can MRBCC assess whether my Mundelein deck is worth resurfacing?
Yes. A surface update depends on the condition of the support structure and its suitability for the proposed material. Photos are helpful for the initial conversation, but a site review is needed before recommending reuse.
How should a deck connect to a Mundelein patio?
Plan the stair landing and walking route before laying out furniture. The deck and patio should work together at their different elevations. Measurements of the existing paving, door, and grade help identify a practical connection.
