Chimney Repair for Dumont chimneys

Most Dumont chimneys are brick, built with the house to serve a furnace or boiler and, in many homes, a fireplace. Over the years, heating equipment has been replaced, and that has changed what the chimney is being asked to do. When an older furnace is replaced with a high-efficiency unit that vents through the side wall, the water heater is often left venting alone into a flue sized for much more, which leads to condensation and poor draft.

Add the usual age-related problems, such as cracked crowns, missing caps, eroded mortar and old flashing, and most Dumont chimneys need some attention after several decades.

We inspect, clean, reline, rebuild crowns, install caps, repoint, waterproof and reflash, and we can check flue sizing whenever heating equipment has changed.

Dumont housing

Dumont is mostly single-family, with homes built from the 1920s through the 1960s on small lots. Ranches, capes and colonials dominate, with some older bungalows and foursquares. Many homes have been expanded with rear additions, dormers or second stories, which often added low-slope roof sections tied into the original roof. Commercial buildings with flat roofs line the main roads.

Weather & exposure

Dumont is inland and fairly level. Street trees and backyard trees shade many roofs and fill gutters each fall, and closely spaced houses mean limited sun on some slopes. Wind-driven rain from nor'easters tests the joints where additions meet the original house. Winters bring freeze-thaw on chimneys and ice dams on poorly ventilated roofs.

Repair, repoint or rebuild in Dumont

If your Dumont home has had its furnace or boiler replaced, ask us to check the chimney, especially if the water heater still vents into it. Visible signs of trouble include a cracked crown, missing cap, white staining, loose mortar or water near the chimney inside.

Most problems are repairable with a liner, crown, cap, repointing and waterproofing. Estimates are free and include photos.

Dumont Specifics

Chimney problems we see in Dumont

Orphaned water heater flues

When a furnace is replaced with a unit that vents out the side wall, the water heater may be left alone in an oversized flue. Exhaust cools and condenses, damaging the flue and affecting draft. A properly sized liner is the fix.

Gas conversion damage

Flues built for oil and later used for gas suffer from acidic condensation. Clay tiles crack and mortar erodes from inside. We inspect and reline as needed.

Cracked crowns and missing caps

Decades of freeze-thaw crack crowns, and missing caps let rain and animals in. We rebuild crowns and install stainless caps.

Short ranch chimneys and flashing

Low chimneys on ranch homes are close to the roof surface, where snow and debris pile up against the flashing. We reflash properly and install crickets on wider chimneys.

FAQ

Chimney Repair in Dumont: your questions

We got a new high-efficiency furnace. Does that affect the chimney?

Often, yes. If the new furnace vents through the wall, the water heater may be left alone in a flue that is now too large for it. That can cause condensation and draft problems. We inspect and install a correctly sized liner if needed.

There is water dripping near my water heater vent. Is it from the chimney?

It can be condensation from an oversized flue, or rain entering through a missing cap or cracked crown. We inspect from the top and bottom to find the cause.

Do I need a chimney cap?

Yes. A cap keeps rain, debris and animals out of the flue. Missing caps are one of the most common causes of chimney damage we see.

Do you clean fireplaces too?

Yes. We clean and inspect fireplace flues, check the damper and look for liner damage. An annual inspection is generally recommended for fireplaces in regular use.
