Chimney services Mount Prospect homes can book

We serve Mount Prospect with the full range of our work. That includes chimney sweeping and flue cleaning, masonry and crown repair, caps and liners, fireplace and insert installation, gas fireplace service, and dryer vent cleaning and rerouting.

Where to start for your project

Planning a new wood-burning, gas or insert unit? Start with fireplace installation for homes in Mount Prospect. It fits most closely if you are finishing a basement or replacing an old unit.

  • If the chimney hasn't been cleaned in a while, or you notice a smoky smell or slow draft, our chimney sweep service is the usual first step.
  • Cracked mortar, spalling brick, a damaged crown or water stains near the chimney point to chimney repair.
  • When the brickwork above the roof is leaning or crumbling past patching, a chimney rebuild replaces the damaged section.
  • An open flue lets in rain, debris and animals; how chimney cap installation works explains the fix.

What local records mean for chimney and fireplace work

Housing age

According to the CMAP Community Data Snapshot (American Community Survey 2020-2024 five-year estimates), 3.3% of Mount Prospect housing units were built before 1940 and 48.2% between 1940 and 1969, with a median year built of 1969. That means roughly half the homes here date from the mid-century decades. In general, masonry chimneys of that age are worth inspecting for worn mortar joints, crown cracks and flue liner condition, especially before a home sale or after a long stretch without use.

Flashing when the roof is replaced

The Village's Residential Roof Supplement (Community Development Department, 2026) requires sidewall and masonry flashings to be metal or lead. Existing flashing may be reused, but all flashing must be weather tight. That is the responsibility of the roofing contractor, or of a homeowner who replaces their own roof. If a reroof is coming up, have the chimney checked first. Any masonry or flashing repair can then be done before the new shingles go on.

Permits and adopted codes

The Village of Mount Prospect's Community Development 'Common Questions' page states that some tasks involving fireplaces require a building permit. Its Building & Inspection Services page lists building codes adopted February 15, 2022, including the 2021 International Residential Code, the 2021 Mechanical Code and the 2021 International Fuel Gas Code. Those codes cover fireplace, venting and gas piping work, so confirm with the Village whether your specific project needs a permit before scheduling.

Fireplaces in a basement remodel

Mount Prospect's 2026 Basement Buildout Supplement requires dedicated gas shut-off valves for all gas appliances. It also lists a fresh air intake as required at any new fireplace in a basement remodel. If you are adding a gas fireplace or gas logs downstairs, plan for both items from the start rather than adding them after the walls are closed.
