Deck builders in Lincolnshire, IL

The median home in Lincolnshire was built around 1991. A deck built with a house of that age is now about 35 years old — the stage where first-generation pressure-treated decks commonly need major repair or replacement.

Decks built before 2004 were very likely made with CCA-treated lumber, which was phased out of most residential uses at the end of 2003. That doesn't make an existing deck unsafe, but old boards shouldn't be burned, and demolition debris should be disposed of according to local rules.

That makes Lincolnshire's housing 8 years newer than Lake County as a whole, where the median home was built in 1983. Statewide, the median Illinois home was built in 1971. Among the 102 covered Illinois communities with Census data, Lincolnshire ranks #92 for oldest housing. In this ZIP code, 8% of homes were built before 1960, 29% between 1960 and 1979, 25% between 1980 and 1999, and 38% since 2000 — the single largest group dates to the 2010s.

The nearest NOAA climate station with 1991–2020 normals is Chicago Palwaukee AP, about 5 miles away. It records an average of 122 days a year with a low at or below 32°F — a substantial freezing season. On roughly 79 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

For Lincolnshire, that means footings must bear below the locally required frost depth to avoid heaving, and wood surfaces should be kept sealed so absorbed water doesn't split boards over winter. Synthetic decking tolerates freeze-thaw well but still needs the manufacturer's expansion gaps.

Average snowfall near Lincolnshire is about 33.6 inches a year (Chicago Botanic Garden). That's enough that shoveling and ice-melt choices affect deck surfaces, and stair treads benefit from good texture and drainage.

Precipitation averages about 32.3 inches a year, falling on about 63 days with 0.1 inch or more — wet enough that drainage and flashing still matter, but dry spells also let wood surfaces dry out and check in the sun.

Average summer highs reach about 82°F, and around 17 days a year top 90°F. On a deck with full afternoon sun, dark composite can get uncomfortable on those days, so test samples in the sun before choosing a color.

Budget, upkeep tolerance and sun exposure on your particular lot still decide the final choice between these options.

Lincolnshire has about 3,680 housing units across its covered ZIP code. 56% are single-family detached homes, 13% are attached homes such as townhouses and rowhouses, and about 31% are in buildings with two or more units. Roughly 80% of occupied homes are owner-occupied.

The mix of detached homes and attached or multi-unit housing in Lincolnshire means deck projects range from large backyard decks to compact rear decks on narrow lots. Lot size, neighbors' sightlines and any association rules shape the right design.

• Replacement and major repair: about 1,554 homes (42%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
• Upgrades and expansions: about 770 homes (21%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.
• Retrofit decks on older homes: about 718 homes (20%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.

Lincolnshire has a defined building season. Spring and early fall offer the most comfortable working weather; winter is a good time to settle the design and apply for permits. Stains and sealers generally need dry weather and moderate temperatures, so plan wood finishing for late spring or early fall.

For Lincolnshire, IL, ask the permit office whether your deck needs a permit based on its size, height and attachment to the house, which drawings and inspections are required.
