    Chimney Repairs and Lining

    Moisture absorbed by chimney bricks, blocks, and mortar — and the freeze and thaw cycles of New England weather — accelerates chimney deterioration. Through age and use, chimneys can require repair and restoration. Armstrong Hearth & Home provides a variety of chimney repair and restoration services to chimneys that are in need of some serious TLC.

    Chimney Damper Repair

    We fix stuck or old dampers by repairing the current damper or installing a new damper. Moisture can rust a damper assembly, speeding its deterioration. 

    Chimney Crown Repair

    The crown, the top most portion of your chimney, is one of the easiest places for moisture to penetrate. As moisture penetrates the crown, it accumulates in the chimney chase area and exits through the chimney wall. A deteriorated, cracked, damaged, or incorrectly built crown needs repair. At Armstrong, we seal chimney crowns and rebuild them if needed. We use CrownCoat, a fast-setting elastomeric coating that forms a flexible waterproof membrane. CrownCoat is specifically formulated to repair and protect chimney crowns from water intrusion. It does this by covering the whole crown, filling any existing cracks to help to prevent further cracks from forming.  If your crown has extreme damage, we can rebuild it from scratch. 

    Chimney Caps and Mortar Joint Repointing

    Uncapped, your chimney presents a hole in your roof. This allows rain and snow to enter your chimney flue, potentially damaging attached heating appliance connections or metal fireplaces and dampers. An uncapped opening also can allow birds, rodents, and other animals to make a home inside your home or chimney. We install stainless steel and copper chimney caps and can custom-build a cap to any size chimney. Our stainless steel chimney caps come with a lifetime warranty. 

    We can repoint failed mortar joints that have deteriorated over time. We grind out failed mortar joints and tuck point to restore masonry. 

    Chimney Water Repellent

    Applying water repellent to your exterior chimney bricks can help prevent costly repairs in the future. Armstrong uses ChimneySaver Water Repellent, a penetrating, VOC-compliant water repellent that contains a proprietary modified siloxane. This water-based siloxane penetrates masonry up to 1/4 inch or more, depending on surface porosity and moisture content at the time of application. ChimneySaver Water-Base Water Repellent reacts with the minerals in masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors.

    Chimney Flashing Sealing

    Flashing is used between the chimney and roof to keep moisture and water out of your home.  We reseal chimney flashing and rebuild it if needed. To seal flashing, we use FlashSeal, an elastomeric sealant specially formulated for permanent adhesion to asphalt shingles, aluminum flashing, brick, and other chimney and roofing materials. It stops problem leaks around the base of chimneys, stacks, and vents, as well as around skylights. FlashSeal repairs flashings that have been tarred, re-tarred, or cracked.

    Stainless Steel Chimney Liners

    Relining your chimney is the least expensive and most practical way to restore use to a damaged, deteriorated, or older masonry chimney. Relining your chimney provides peace of mind that your chimney is suitable for continued use. At Armstrong we use only top-of-the-line titanium blend stainless steel chimney liners, which protect the inside of your chimney and have a lifetime warranty with annual inspection.

    Older clay-lined chimneys are susceptible to accelerated deterioration from modern heating appliances. Chimneys that never had a chimney liner need one for proper operation. Age and moisture can cause the interior of lined and unlined chimneys to crack and collapse into itself. Today’s modern gas and oil-fired appliances require a properly sized liner. 

    A chimney fire, lightning strike, falling trees, and other disasters can damage fragile tile liners, causing them to crack. An annual chimney inspection can often identify early signs of deterioration so preventive measures can be taken.

    Armstrong specializes in restoring and servicing chimneys and can complete a full chimney rebuild if needed.
