Complete Roof and Chimney Repair Services in Wilmington, DE
A failing chimney is one of the most common, and overlooked, sources of severe roof leaks. Water infiltrating damaged chimney masonry can quickly rot surrounding roof decking, destroy interior drywall, and weaken ceiling joists.
Chimney Flashing Repair & Installation
Chimney flashing seals the vulnerable gap where your chimney meets the roof deck. When flashing lifts, rusts, or breaks down, rainwater flows directly into your home. We install custom-crafted metal flashing systems and counter-flashing that create an impenetrable, watertight seal between your roof shingles and masonry.
Chimney Crown Repair & Sealing
The concrete crown sitting on top of your chimney is its first line of defense against rain and ice. Cracks in the crown allow water to seep into the brickwork, freezing and expanding during winter months. We perform durable crown repairs, apply flexible waterproof sealants, or pour full crown replacements to prevent costly structural deterioration.
Masonry Repointing & Brick Repair
Repointing (or tuckpointing) restores decaying mortar joints between your chimney’s bricks. Fresh, expertly applied mortar prevents water intrusion, restores structural integrity, and renews your chimney’s exterior appearance without requiring a full tear-down.
Chimney Rebuilding & Demolition
When structural damage, settling, or severe storm impacts compromise your chimney beyond simple repairs, you may need a complete or partial rebuild. We safely dismantle failing masonry structures and rebuild sturdy, beautiful chimneys engineered to meet all local building codes.
Waterproofing & Sealing
Brick and mortar absorbs moisture during rainstorms. Our commercial-grade breathable masonry sealants prevent water absorption, stop freeze-thaw spalling, and extend the lifespan of your chimney structure.

Signs Your Chimney Needs Repair or Replacement
Chimney damage is not always obvious from the ground. Small cracks, failing mortar, or loose flashing can gradually allow moisture into the structure and surrounding roof system. Knowing what to look for can help you address problems before they worsen.
Cracked or Crumbling Mortar
Mortar joints naturally deteriorate with age and weather exposure. If you notice cracking, missing mortar, or joints beginning to crumble, you may need repointing to restore stability and limit moisture intrusion.
Loose, Cracked, or Spalling Bricks
Bricks that are cracked, flaking, bulging, or pulling away from the chimney can indicate ongoing moisture damage or structural movement. Localized damage may be repairable, while widespread deterioration can require partial or complete rebuilding.
Water Stains Near the Fireplace or Ceiling
Discoloration on ceilings or walls near the chimney may indicate a problem with flashing, masonry, the chimney crown, or surrounding roofing materials. Because water can travel before becoming visible inside, a professional should inspect the actual source.
Damaged or Missing Chimney Flashing
Flashing creates a seal where the chimney meets the roof. Rusted, loose, lifted, or improperly installed flashing can let rainwater beneath the roofing system and into the roof deck or the home’s interior.
Cracks in the Chimney Crown
The chimney crown directs water away from the masonry below. Cracks can let moisture penetrate the structure, where repeated freezing and thawing may contribute to further deterioration.
Leaning or Unstable Masonry
A chimney that appears to be leaning, separating from the home, or developing large structural cracks should be evaluated promptly. Significant movement may indicate that repairs alone are no longer sufficient and that rebuilding may be necessary.
If you notice any of these warning signs, a professional chimney inspection can help determine whether targeted repairs, masonry restoration, or a larger rebuild is the most appropriate solution.
Frequently Asked Questions About Chimney Services
How can I tell if a ceiling leak is coming from my chimney or my roof?
Chimney-related leaks often appear on ceilings or walls near the fireplace, chimney chase, or flue. Common causes include deteriorated flashing, cracks in the chimney crown, damaged mortar joints, or masonry that has begun absorbing moisture. Because water can travel before becoming visible indoors, a professional inspection can help determine whether the source is the chimney itself, the surrounding roofing materials, or the transition between the two.
What is chimney repointing, and when is it needed?
Chimney repointing involves removing deteriorated mortar from the joints between bricks and replacing it with new mortar. This process helps restore the masonry’s strength and reduce opportunities for water intrusion. Repointing may be recommended if you notice cracked or crumbling mortar, loose bricks, visible gaps in the joints, or moisture entering around the chimney.
How long does chimney flashing typically last?
Properly installed metal chimney flashing can last for many years, but its service life depends on the material, installation quality, weather exposure, and condition of the surrounding roof. Aluminum, galvanized steel, and copper all perform differently over time. High winds, temperature changes, aging sealants, and roof movement can eventually create gaps or loose sections, which is why periodic inspections help catch problems before they develop into leaks.
