New wood-burning fireplaces installed in Isleworth

Chimney parts from the same system

Factory-built fireplace manuals specify the chimney system to be used. The E-series manual we reference requires its maker's own chimney system and shows only the chimney components that may be safely used with the fireplace, from straight sections to offsets, firestops and termination caps.

Mixing parts from another brand because they look alike breaks the listing, even when the diameters match. Our estimate lists each chimney component by the system it belongs to, and we do not substitute on install day because a supplier ran short.

How a fireplace installation estimate should read

A clear fireplace estimate separates the fireplace unit, the chimney system and its roof parts, the framing or chase, the hearth extension, the face finish, removal of any old unit, the outside air supply, permit fees and any electrical work by an electrician.

Every line carries upfront pricing with no hidden fees, so you can compare our proposal fairly and see exactly where the money goes. Book within 72 hours after the inspection and 10% off is applied right on the estimate.

• Permit and inspection coordination

Sealing gaps around the fireplace face

Where the face finish meets a factory-built fireplace, small gaps can let room air leak into the enclosure and cold or humid air leak out. The E-series manual describes sealing those joints with noncombustible sealant, so the face stays tight without trapping heat.

We seal the joints the manual names and leave the cooling slots open, because the two are easy to confuse. The finished edge should look crisp, the doors should close against a clean frame and no gap should whistle when the air conditioning starts.

What drives the cost of a new fireplace

The biggest cost drivers are the type of fireplace, the length and route of the chimney, the roof and chase work, the hearth and face finish, and whether an old unit has to come out first. Permit and electrical work add their own lines.

We explain each driver for your project at the free inspection and put them in writing with upfront pricing, so you can adjust the plan knowing which choices move the total. Sometimes a different wall or a shorter chimney route changes the number more than a different fireplace does.
