Winnetka, Cook County

What we get called for in Winnetka.

Hundred-year-old homes with three generations of mechanical work layered on top of each other. Reading what is there matters more than replacing it.

Cold radiators, hot billsWe offer boiler installation and replacement for hydronic heating. Heating-boiler repairs are limited to systems installed by Frolkin within the first year. The office confirms warranty eligibility.
No ducts, no coolingPlenty of Winnetka houses were never ducted. High-velocity or ductless gets you cooling without tearing out plaster.
Basement water and backupsEjector pits, backwater valves and sump systems. After one bad storm, most owners want the whole picture, not a pump swap.
Knob and tube leftoversStill hiding in ceilings and closets here. We map what is live before quoting anything.
Plaster, hardwood and a hundred years of layers.
How we work here

Plaster, hardwood and a hundred years of layers.

We protect finishes, cut only where we must, and tell you when the honest answer is that the tidy solution costs more. No drilling first and explaining later.

  • Boiler installation and eligible first-year Frolkin warranty repairs
  • Ductless and high-velocity retrofits
  • Backwater valve and ejector work
