Chimney Repairs In Derry, NH

Derry, NH, the most populous town in Rockingham County, is beloved for its beautiful, towering oak and pine trees, as well as its abundance of parks, recreational trails, and green spaces that residents enjoy. During the winter, locals visit one of the many nearby ski resorts and then relax at home by a crackling and aromatic wood fire. While fireplaces are a popular feature in New Hampshire, the brutal winter weather makes chimney repairs inevitable. For over twenty years, New Englanders have relied on the certified professionals at Sweepnman for all their chimney repair needs.

How Small Chimney Leaks Can Escalate Into Major Water Damage

Water is the “mortar” enemy of a masonry chimney. What starts as a tiny crack in your chimney crown or a loose piece of metal flashing can quickly escalate into major water damage.

In Southern New Hampshire, we experience freeze-thaw cycles throughout the long winter. When rain or snow seeps into small cracks in our masonry, it freezes when temperatures drop below 32°F. Since ice molecules are larger than water molecules, ice expands, further breaking the masonry apart from the inside and widening the cracks. During the next precipitation event, additional water fills these larger cracks, freezes again, and expands once more.

This vicious cycle not only destroys the brickwork, but it can also damage your home. Once water penetrates your home's wood framing, it can cause rot, damage ceilings, breed toxic mold, and rust your fireplace damper. What may have been a minor repair can quickly become a costly rebuild if left unchecked.

Types of Chimney Repairs Common in Derry, NH

To protect your home and keep your fireplace structurally sound, our team offers specialized repair services:

Chimney Crown Resealing/Rebuilding

For minor cracks, we can apply a flexible, waterproof elastomeric coating. If crowns are severely compromised and show signs of crumbling or significant deterioration, we recommend rebuilding a properly sloped crown with a drip edge.

Flashing Replacement

Chimney flashing is the sheet metal that seals the seam where your chimney meets your roof. Since compromised flashing allows water to damage the masonry walls, we install new stainless-steel flashing to ensure a completely watertight seal.

Brick Replacement

Spalling brick is the leading cause of structural collapse. We carefully replace the damaged masonry with matching bricks that complement the existing materials.

Tuckpointing

When the brickwork is intact, but the mortar is deteriorating, our skilled masonry contractors will perform tuckpointing to replace the decaying mortar with a fresh, durable, water-resistant compound, restoring the chimney’s strength and appearance.

Chimney Cap/Chase Cover Installation

The chimney cap covers the top of a masonry chimney stack, while the chase cover protects a prefabricated chimney. We install high-quality chimney caps and chase covers to keep rain, snow, debris, and local wildlife out. These components come in a variety of materials and styles, so you can choose the signature look you want for your chimney.

Chimney Relining

Many homes in Derry, NH, have clay tile liners that are cracking due to moisture exposure or a prior chimney fire. When this essential safety component cracks or deteriorates, we install a modern stainless-steel liner to improve the draft and ensure smoke and toxic combustion gases are efficiently expelled from your home at the top of the stack.
