Chicagoland's Premier Commercial Cleaning Company
Cortex Cleaning is based in Geneva, IL, and construction cleaning is one of the more physical services we run. Dust in the vents, film on the glass, adhesive residue on the floor, a fine layer of grit on every surface a trade crew touched on their way out.
Post-construction cleaning is the last step between the work being done and the space actually being usable. Because our crews are local rather than dispatched in from another county, we can walk a job site the same week it wraps, not whenever the schedule allows.
Timing matters more than most people expect. The work goes best once every trade is finished, there’s no one still on-site running equipment, and the space is clear enough that every surface is actually reachable.
Booking too early, while an electrician is still pulling wire or a painter’s touching up trim, usually means redoing sections a second time once the last person leaves. If a project is close but not quite finished, tell us during the walkthrough and we’ll help figure out the right week to come in.
Years in business · Insured & certified Geneva crews
Plenty of cleaning companies list Geneva as a stop on a route that covers half the county. Cortex Cleaning is actually from here.
We’ve been doing this for more than 10 years, every crew is fully insured and certified, and being local means a general contractor finishing a job on Third Street or in one of the corporate parks just outside town can get someone out for a walkthrough without waiting on a company headquartered somewhere else entirely.

Same-Week Walkthrough
A full job runs in three passes, and knowing which one you need keeps the quote accurate.
01
A rough clean comes first: bulk debris out, packaging gone, the heaviest dust knocked down so the space is safe to walk through and work in.
02
A final clean follows once the rough work is done. Every surface dusted, windows and sills wiped, floors prepped for whatever finish comes next.
03
A touch-up clean often gets booked separately, after furniture and fixtures move in, to catch the marks and dust that the move-in process itself tends to leave behind. Some jobs only need one of these stages; larger buildouts usually need all three.
Beyond the three stages, the actual task list depends on the materials involved.
Hardwood and natural stone need gentler products than standard construction dust calls for, since the wrong cleaner can dull or etch a finish that took real money to install.
Stainless steel gets wiped and polished rather than scrubbed, to avoid scratching.
Concrete and epoxy floors common in warehouses take a heavier-duty pass than an office carpet would.
Vents, light fixtures, baseboards, and cabinet interiors, the spots a general contractor’s crew rarely gets to, are where fine construction dust actually collects, and they’re a standard part of the final clean.
One thing worth being upfront about: this service handles cleaning, not hauling. Large debris, scrap materials, and leftover construction waste should be cleared by the general contractor before we start the rough clean.
Talk to a real person about your build-out, your timeline, and which stages you need.
Office build-outs need every surface detailed before a tenant moves in on a fixed date.
Retail renovations need storefronts and fixtures spotless before a public reopening that’s already been announced.
Historic restorations, common in the downtown corridor, need cleanup that respects original materials uncovered mid-project rather than a generic approach that treats a century-old surface like drywall.
New warehouse and corporate-park construction in and around Geneva needs large-footprint debris and dust cleared before racking and equipment installation can even begin.
Need post-construction cleaning before a build-out is ready for occupancy.
Need it scaled to floor plans measured in tens of thousands of square feet.
