Deck Contractors in Algonquin, IL

If you are looking for deck contractors in Algonquin, IL, the first thing we look at is where your house sits. The Fox River runs north to south straight through downtown, and the land climbs away from it on both banks. Algonquin was steep enough that automobile makers came here from 1906 to 1913 to test cars on the Algonquin Hill Climbs, using hills that are now residential streets like Huntington Drive and Lundstrom Lane. A yard that drops off behind the house is common here, and it changes how a deck is framed, how tall the posts run and how the stairs land.

Old Town versus the newer subdivisions

Algonquin has two very different housing stocks. Along Main Street (Route 31) and the river, you find older homes from the era when the town was a quasi-resort for Chicago-area visitors, and the village's first National Register listing, the 1894 Queen Anne Christian Geister House at 302 S. Main Street. Out toward Randall Road, the village filled in with subdivisions during heavy residential construction through the 1980s, 1990s and 2000s, in areas such as Algonquin Lakes on the east side and Manchester Lakes on the far west side. Many of those homes were sold with a pressure-treated deck that is now 20 or 30 years old.

The work is different in each place. An older home near the river often needs a deck that fits an irregular back wall, an existing porch or a tight lot. A subdivision home usually needs a replacement: the old boards and railings come off, we check the ledger and footings, and we decide with you whether the frame can carry new decking or whether a full rebuild makes more sense.

What we build in Algonquin

• Composite decks for owners who want to stop sanding and staining every few years
• Wood decks in pressure-treated lumber or cedar when budget or style calls for natural wood
• Deck repair and replacement for the many decks built during the 1990s and 2000s growth years
• Covered decks and pergolas for west-facing yards that bake in the afternoon
• Railings and stairs, including multi-level stairs that step down a sloped lot toward the yard
• Staining and sealing for wood decks that have grayed out

Two counties, one village

About 78% of Algonquin lies in McHenry County and the rest in Kane County. For a deck, the village is the permitting body regardless of which county your parcel is in, but it is worth knowing your county when you look up your plat of survey or property records, since those come from the county. We ask for your plat early so we can show the deck's distance to lot lines on the permit drawings.

Built for Chicago-area winters

The region has a hot-summer humid continental climate. Nearby Elgin averages a January low of 14.1°F and about 32 inches of snow a year, and has recorded lows of -27°F. Water that gets into footings, ledger connections or end grain freezes and expands, over and over. We set footings to the depth the village requires, flash the ledger where the deck meets your house and leave gaps between boards so snowmelt drains instead of sitting on the surface.

How a project starts

Call (847) 380-8109 or send photos of your yard and the back of the house. We visit, measure, look at the slope and the condition of any existing deck, and give you a written quote that spells out materials, railing style, stairs and permit handling. If you would rather replace the decking this year and add a pergola later, we can split the quote into phases.
