Before your smoke chamber is repaired in Robinson Hills
Throat, walls, shelf and flue joint, in the order our Robinson Hills team checks them.
Why the chamber narrows toward the flue
The chamber walls lean inward as they rise, turning a wide opening into a flue-sized passage. How they lean matters. Even slopes guide smoke upward with little turbulence, while abrupt steps and pockets make it tumble and linger.
When we look at a chamber, we note whether the walls taper evenly on all sides or whether one wall leans harder than the others. A lopsided chamber is one of the conditions a thick parging coat can sometimes correct.
Refractory mortar and ASTM C199
ASTM C199 is the test method the code names for refractory mortars, the heat-rated mortars used inside fireboxes and smoke chambers. The code calls for parging made from mortar that conforms to it, and for firebrick linings laid in medium duty refractory mortar.
In practice, that means the product in a bucket on our job has been made and rated for fireplace heat. Ordinary masonry mortar is made for walls and weather. We name the refractory product we plan to use in the written estimate, so there is no question about what goes on your chamber walls.
Clearance from framing around the fireplace
Section R1001.11 sets how close beams, joists, studs and other combustible material may come, 2 inches from a masonry fireplace's front and sides and 4 inches from its back. The smoke chamber walls are part of that masonry.
That clearance assumes the masonry itself is continuous. Open joints and missing mortar inside the chamber break that continuity. Sealing and parging the chamber restores the masonry face on the inside, and anything we can see about nearby framing goes into the written findings.
Soot marks on the fireplace face
Dark streaks on the brick or stone above a fireplace opening show that smoke has been escaping at the top edge of the opening. The chamber can be part of the reason, along with the damper, the flue and the way fires are laid.
We note the pattern of the marks, check the parts above them and explain which ones play a role. Cleaning the fireplace face is separate from chamber repair, and we can advise on it without adding it to the job.
Upfront pricing on chamber repair
Chamber repair can sound open-ended, since the chamber is out of sight. Our pricing is upfront. After the free inspection, every part of the job has its own price on the written estimate before any work starts.
No hidden fees are added later. If cleaning reveals something new, we stop, show you and give you the choice. The price you approve is the price of the work described.

Quick chamber facts for Robinson Hills fireplaces
Missing your question? Our Robinson Hills crew will answer it by phone.
How soon can I light a fire after the chamber is parged?
That depends on the product. One maker calls for a full day of air curing with the damper open, then a small conditioning fire and small fires for several days. We write the steps and the first fire date on your invoice.
Is the inspection really free?
Yes. Our free inspection covers the chamber, the smoke shelf and the damper area, and the written estimate that follows costs nothing either. You decide afterward, with no obligation.
