A farming village with an old Main Street
Durham began as a farming village on the Coginchaug River, and its center still shows it. The Main Street Historic District covers about 160 acres at the heart of town and is known for the architecture of its houses. Beyond the center, older farmhouses share the roads with homes built in later decades, many on large wooded lots.
To the west, the trap rock of the Metacomet Ridge rises in Trimountain, Fowler Mountain and Pistapaug Mountain, with the Mattabesett Trail running along the heights. Houses near the ridge or on open farmland catch more wind, and a tall chimney on one of them takes the brunt of driving rain in a storm.
Three kinds of Durham house, three kinds of chimney
Historic homes in the center
Large brick or stone stacks, often serving more than one fireplace, sometimes unlined. Mortar loss, a worn crown and a damper that no longer seals are typical findings, and repairs should suit the age of the house.
Farmhouses that grew over time
Many old farmhouses gained additions, and with them a second chimney or a stove flue added decades after the first. Where old and new work meet is a common spot for leaks and gaps in the flashing.
Later homes on wooded lots
Usually a masonry chimney for the furnace or boiler and a fireplace, or a factory-built fireplace inside a sided chase. Leaves, animals and a rusting chase cover are the usual concerns here.

Old chimneys need a gentler hand
Chimneys in the oldest houses were often built without a flue liner, from soft brick or stone laid in lime mortar, and sometimes with several fireplaces feeding one large stack. They can work for centuries, but they were not designed for a modern stove or for the heat and moisture of today’s heating equipment.
Repairs should respect how the chimney was built: compatible mortar, matching materials and a liner sized for whatever burns below. Our historic chimney restoration page explains that approach, and chimney liner types compares the relining options for an old flue. Before any relining, the inspection should confirm that the masonry around the flue is sound, because a liner protects the house from the smoke but does not hold up crumbling brick.
Recent work: a partial chimney rebuild
The same chimney, during and after the work. The damaged top courses come down with the roof covered in tarps, then the top is rebuilt and finished with a new crown.
Wood from your own lot is a fine fuel once it has had time to dry. Freshly cut wood holds a lot of water, and burning it cools the flue and speeds up creosote buildup. Split it, stack it off the ground with the top covered, and give it at least six months, ideally a year, before it goes in the stove.
Repair or rebuild: what Durham homeowners should weigh
Match what you see to the likely fix. These are ballpark Connecticut ranges for 2026, for planning only; your own price is put in writing once we have seen the chimney, at no charge. For the full decision process, read repair vs. rebuild.
| What you see | Likely fix | Ballpark |
|---|---|---|
| Hairline cracks in the crown, top bricks solid | Crown repair or sealing | $200–$1,200 |
| Joints eroded, bricks still sound | Tuckpointing / repointing | $800–$3,000+ |
| Flue tiles cracked, missing or never installed | Stainless liner | $1,500–$4,000+ |
| Loose or leaning section above the roof | Partial rebuild | $3,000–$8,000 |
| Widespread damage below the roofline | Full rebuild | $8,000–$20,000+ |
| Buying the house, after a chimney fire, or changing fuel | Level 2 inspection (paid) | $250–$500 |
Getting ready for heating season
Durham Fair weekend each fall makes a handy reminder that the heating season is close. Before your first fire of the year:
- Book a sweep and inspection if you burned wood regularly last winter
- Burn only seasoned wood, and stack it away from the house
- Check that the damper opens and closes fully
- Look up at the chimney from the yard for a missing cap, loose bricks or a cracked crown
- Test smoke and CO detectors and replace batteries as needed
- Have branches cut back if they hang over the chimney
- Keep a lidded metal ash can outside, away from anything that burns

Booking from Durham
Durham borders Middlefield, Middletown, Wallingford and Haddam, and our Middlesex County service covers the whole area. Phone (203) 779-6787 between 7 AM and 8 PM from Sunday to Thursday, or before 2:30 PM on Friday. Any other time, send the callback form and we will reply once the office opens.
If the house is old, tell us roughly how old and whether any flues are closed off or unused. That way the visit can cover every flue in the stack, including ones that have not seen a fire in years.
