Lexington's pre-1960s housing stock includes many original masonry chimneys, and a chimney inspection is a routine part of due diligence for buyers on these older homes.
Lexington's housing spans homes dating to the 1690s, like the Buckman Tavern, built around 1704–1710, through the large 1950s–70s subdivisions — the older end of that range is where our matched contractors most often find masonry and flue issues that have gone unaddressed for decades.
Whether you've noticed crumbling mortar, a water stain near the chimney, or you're just due for a routine inspection, getting a professional look is the first step. It's quick and gives you a clear answer before you commit to anything.
How Chimney & Masonry Repair Typically Works
1. Inspection
A technician examines the chimney's exterior, flashing, crown, and (often via camera) the interior liner to identify cracked mortar, spalling brick, or liner damage. A Level 1 or 2 inspection typically runs $150–$500.
2. Repointing vs. Rebuild
Minor mortar joint damage is usually fixed with repointing (grinding out and replacing damaged mortar). Significant structural damage, leaning, or major spalling may require a partial or full rebuild.
3. Liner Assessment
Older chimneys, especially those converted from oil to gas heat, often have liners that were never updated for the new fuel type — a common and important finding during inspection.
4. Flashing & Crown Repair
Where a chimney meets the roof, worn flashing and cracked crowns are common sources of water intrusion, and are often addressed alongside masonry repair.
5. Permits
Most repointing does not require a permit; a full rebuild or structural work commonly does. Check with your local building department for your specific project.
6. Typical Costs
Repointing: roughly $500–$2,500 depending on extent. Crown/flashing repair: $300–$1,500. Partial to full rebuild: $2,500–$10,000+. Every chimney is different — a quote reflects your specific property.

Common Questions
How do I know if my chimney needs repair?
Common warning signs include crumbling or missing mortar, white staining (efflorescence), a leaning structure, water stains on ceilings near the chimney, or a musty smell when the fireplace is in use. Many issues are only caught during a professional inspection.
Do I need to reline my chimney if I switched from oil to gas heat?
Often, yes. Different fuel types have different liner requirements, and a liner sized for oil heat may not be appropriate or safe for a gas appliance. An inspection will confirm what your specific system needs.
