Chimney Sweep & Repair in Middlefield, CT
Sweeping, inspection and repair for Middlefield and Rockfall homes, from 18th-century saltboxes to houses near Lake Beseck and newer homes with prefab fireplaces.
Sunday to Friday
A Class Chimney cleans, inspects and repairs chimneys in Middlefield and the village of Rockfall, whether your house is a centuries-old saltbox or a newer home with a factory-built fireplace. The visit includes photos of what we find and a written price, and it costs $59. A standard cleaning with a Level 1 inspection is about $150–$350 as a ballpark.

Saltboxes, ridge views and Lake Beseck
Middlefield takes its name from its position between Middletown, Durham and Meriden, and the village of Rockfall sits in its northeastern corner. The traprock heights of Higby and Besek Mountains, part of the Metacomet Ridge, flank the west side of town, Lake Beseck lies just off Route 147, and Powder Ridge and Lyman Orchards are familiar landmarks.
The town seal shows the 1700s saltbox houses that still stand here. Housing ranges from those and old farmhouses to homes around the lake and newer neighborhoods. A classic saltbox has a large central chimney serving several fireplaces, which brings very different issues from a modern home’s single flue. Houses on higher ground toward the ridge also face more wind, which drives rain into the top of a chimney.
Inside an old central chimney
A central chimney in an 18th-century house is a big masonry mass that starts in the cellar and rises through the middle of the home, often with two or three fireplaces built into its sides. The flues inside may have been laid without liners and separated only by a single layer of brick, called a wythe.
Over two or three centuries, that inner brick can erode or crack, so smoke from one fireplace may find its way into another flue or into the house. The base in the cellar deserves a look too, since settling or water damage there affects everything above. The top, where the stack passes through the ridge, is a common place for leaks.
None of this means the chimney is finished. Old central stacks can often be kept in use by relining the flues you want to burn in and capping or sealing the rest, with mortar repairs that suit the original materials.
Chimney symptom checker
Tick what you have noticed and see what it usually means.
Old fireplaces in a saltbox are wide and shallow and their flues are large, which is a poor match for a modern stove or insert without a dedicated liner. Have the chimney inspected and plan the liner before you buy the stove, so the two are sized for each other.
Chimney trouble by season
Chimney problems tend to follow the calendar. Here is what usually shows up, and when.
Spring
Thaw and rain reveal winter damage: cracked crowns, loose top bricks and new leaks. Our leak guide helps you narrow down the source.
Summer
Humid air can pull a sour, tarry smell out of a flue coated with creosote; see why a chimney smells. Chimney swifts may also be nesting in an uncapped flue.
Fall
The best window for a sweep, a new cap and small repairs before daily fires begin. Swifts have usually left by then, so a flue they used can finally be cleaned and capped.
Winter
Draft problems surface once fires are lit every day. Smoke spilling into the room points to a blockage, a damper issue or a flue that is too short or too large. Read about smoky fireplace draft problems.
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.


Newer homes with factory-built fireplaces
Many homes built from the 1970s on have prefabricated fireplaces with a metal flue inside a framed chase, often finished in siding. There is no brick to repoint, but they have their own weak point: the metal chase cover on top. Painted or galvanized covers rust, and then rainwater pools and runs into the chase.
Rust streaks on the siding below the top, or water stains around the fireplace, are the signs to watch for. A stainless replacement cover, ballpark $400–$1,200, fixes most of these, with the exact price set in writing after the $59 on-site inspection. Details are on our prefab chimney and chase repair page.
Call when you notice any of these
One sign on its own is enough reason for a look:
- Water in the firebox after a storm
- A cracked or crumbling crown visible from the yard
- Rust stains on the siding of a chase
- Smoke drifting into the room when the fire is lit
- A tar or campfire smell in warm weather
- Birds or animals heard in the flue
- Mortar dust or flakes collecting on the hearth
