When to pick up the phone
Most of Markham's homes went up between the 1940s and 1970s, so plenty of original foundations and framing are still underground or hiding behind old trim. Here's what to look for.

What the calendar changes
Termite swarms around Markham usually show up May through June, when winged termites leave an established colony to start a new one nearby. Cold winters slow things down above ground. But crawl spaces and soil near the foundation stay workable for termites most of the year, so a quiet winter doesn't mean a clear crawl space.

Local conditions that shape the work
Markham grew fast between the 1940s and the 1970s, which is a polite way of saying most homes date back to that era. Foundations are a mix of poured concrete crawlspaces and full basements, with some slab-on-grade ranch homes mixed in. Nobody was building with today's termite barriers back then, and decades of settling, moisture, and small repairs can open gaps that subterranean termites use for years before anyone notices.
The clay and silty clay loam soil common across the Chicago lake plain drains poorly, so water sits near foundations longer than it would in sandier ground. That's exactly what subterranean termites look for. A damp crawl space in Markham isn't just a mildew problem, it's sitting on conditions termites find easy to work with. Older homes near Hazel Crest, Posen, and Harvey share the same soil and the same housing age, so this pattern isn't unique to one block.

Before you call
How common are termites in Markham homes?
Subterranean termites are a known pest across south Cook County, and Markham's clay soil holds moisture near foundations longer than sandier ground would. Add in a housing stock mostly built in the 1940s through 1970s, and older crawlspaces and foundations end up more exposed to termite entry points than newer construction.
What does termite treatment cost for a Markham home?
Typical jobs run from around 800 dollars for a basic liquid barrier on a smaller foundation up to 2,500 dollars when damage repair's included. The provider sets the final price after inspecting your foundation type, crawl space access, and the extent of any wood damage found.
Is a slab home in Markham less likely to need termite treatment?
Not necessarily. Slab-on-grade ranch homes still have foundation edges and utility penetrations where termites get in, and Markham's poor-draining clay soil affects slab homes too. An inspection is the only reliable way to know, whatever the foundation type.
When do termites swarm in the Markham area?
Swarms typically happen May through June in the Chicago area, when winged termites leave an established colony. Seeing a swarm, or a pile of shed wings on a windowsill, usually means there's already a colony nearby. Worth a call that same week.
Does calling this line cost anything?
No. It's free to call, no obligation to book anything. An independent licensed provider serving Markham takes the call, inspects if needed, and gives you a written quote before any work starts.
