Do You Have a Rampart General Chimney?

Southern California homeowners occasionally hear the name “Rampart General” when discussing chimney issues and the chimney industry in general. Rampart General is the name of a series of precast chimneys that were made by a now-defunct Santa Ana, CA, company and added to many homes built in the 1970s and 1980s.

Chimney Sweep Inc., of Lakeside, CA, knows all about the nightmarish problems with Rampart Generals, commonly referred to as “Ramparts,” and we’d like to share a little of the story with you.

What is a Rampart General Chimney?

These chimneys are all-in-one structures, poured at construction sites and then lifted into place with heavy machinery. Most Ramparts are white or a variant of white. To the untrained eye, the surfaces appear to be brick, but they’re actually just a single slab of cement.

Rampart General chimneys were usually set against exterior walls of homes. The flue sections of the chimneys are notable in that they’re narrower than those of traditional masonry chimneys.

Rampart Generals are most often found in Southern California, with many having been erected at San Diego County homes.

What’s Wrong with Ramparts?

There are three major, irreparable problems with a large number of the Rampart Generals that are still in use.

Cracked Insulation Plate

Located just above the firebox, Rampart General chimney insulation plates are notorious for cracking. When this happens, there’s an immediate high risk of fire spreading from the chimney to adjacent materials of the home.
When the insulation plate is cracked, not only is there no viable repair method, but the chimney is no longer safe to vent any other type of appliance, such as a stove, fireplace insert, furnace or boiler.

Flue Lining Damage

The third major Rampart problem for which there is no remedy is damage to the flue lining. It appears that the horizontal construction process made it relatively easy for sections of the flue material to detach and fall away when the chimney was raised into place.

In working with “normal” chimney flues, we know firsthand that any kind of breaks, tears, holes or jagged edges in a flue can lead to major drafting problems and fires in the chimney and in the home. Damage in a Rampart General flue makes the chimney phenomenally dangerous.

Structural Cracks

When a brick-built chimney’s masonry suffers damage, we often find individual bricks cracked or in some state of decay. When a Rampart General’s masonry becomes damaged, you usually see very long vertical splits because the entire chimney is one piece. With Ramparts, cracking doesn’t stop at a masonry joint; rather, it just keeps on lengthening.
At Chimney Sweep Inc., we’re not precast chimney designers, so we won’t venture a guess about what was going through the manufacturer’s mind when designing and building these dangerous chimneys. We do know that we’d never create anything like them.
