Fix it right: (815) 296-8285 · Tuckpointing, rebuilds, flashing & firebox · Insured & Bonded · Romeoville, IL
Chimney repair covers the masonry and structural work that keeps water, heat, and gases where they belong — tuckpointing crumbling mortar, rebuilding damaged brickwork, sealing flashing, repairing the crown and firebox, and waterproofing. Water is the number-one enemy of a masonry chimney, and small problems left alone become expensive rebuilds. Masterful Chimney Sweep repairs chimneys across Romeoville with an honest assessment of what actually needs doing. Call (815) 296-8285 to get started.
The repairs we handle most
- Tuckpointing — grinding out failed mortar joints and repacking them with fresh mortar. This is the most common masonry repair and it stops water from working its way into the structure.
- Brick and block rebuilds — rebuilding the section of a chimney above the roofline (or lower) when freeze-thaw damage has spalled the brick beyond patching.
- Crown repair and replacement — sealing or recasting the concrete crown at the very top, which sheds water away from the flue and masonry.
- Flashing repair — resealing or replacing the metal flashing where the chimney meets the roof, a leading cause of ceiling stains near the chimney.
- Firebox repair — replacing cracked firebrick and failed refractory mortar inside the firebox so heat stays contained.
- Waterproofing — applying a vapor-permeable sealant that repels water while letting the masonry breathe.
Why water damage gets expensive fast
A masonry chimney takes weather from every side and from above. When the crown cracks or the mortar joints open up, rain soaks into the brick. Through an Illinois winter that water freezes and expands, breaking the masonry apart from the inside — the spalling and flaking you can see on many older chimneys. The same water rots the flashing seal and stains ceilings inside the home. Catching it at the tuckpointing stage costs a fraction of what a partial rebuild costs later, which is why we flag masonry issues during every inspection.
Signs your chimney needs repair
- White staining (efflorescence) or a chalky residue on the exterior brick.
- Crumbling, cracked, or missing mortar between the bricks.
- Flaking, spalling, or pieces of brick on the roof or ground.
- A cracked crown at the top of the chimney.
- Rust on the damper or firebox, or a water stain on the ceiling near the chimney.
- Gaps or loose metal in the flashing where the chimney meets the roof.
Our approach to repair work
Masonry is skilled work, and matching mortar and brick on an older Romeoville chimney takes experience. Owner Leo Jenkins has spent 18 years doing exactly that. We start with a clear inspection, show you photos of the damage, and give you an up-front quote that separates the work that is urgent from the work that can wait. We are insured and bonded, so the crew is covered before anyone gets on your roof. If a repair uncovers a liner problem, we can also handle relining so the whole system is sound. Current starting prices are on our pricing page.
Frequently asked questions
What is tuckpointing?
Tuckpointing is the repair of the mortar joints between bricks. We grind out the old, failed mortar and repack the joints with fresh mortar, which restores strength and keeps water out. It is the most common chimney masonry repair.
How do I know if I need a repair or a full rebuild?
It depends on how far the damage has spread. Isolated cracked joints usually call for tuckpointing; widespread spalling and loose brick above the roofline often means rebuilding that section. Our inspection and photos make the answer clear.
Why is my chimney leaking?
The most common causes are a cracked crown, open mortar joints, a missing or damaged cap, and failed flashing at the roofline. We trace the source rather than just sealing over it.
Can you match the brick and mortar on my older chimney?
Yes. Matching color, texture, and joint style is part of doing masonry repair correctly, and it is something experience makes a real difference on.
Does waterproofing really help?
A proper vapor-permeable sealant repels rain while still letting the masonry release moisture. Applied after any needed repairs, it meaningfully slows freeze-thaw damage. We do not recommend a hardware-store sealer that traps moisture inside the brick.
How long do chimney repairs take?
Tuckpointing or a crown repair is often a one-day job; a partial rebuild takes longer and depends on weather. We give you a realistic timeline with the quote.
Do not ignore a chimney leak
A chimney leak rarely fixes itself, and the damage compounds every time it rains. Water that gets past a cracked crown or open joint travels down through the masonry, rusts the damper and firebox, rots roof framing, and eventually shows up as a stain on a ceiling or wall. By the time the stain appears, the water has usually been getting in for a while. If you see any sign of water near your fireplace or on the chimney exterior, call (815) 296-8285 and we will find the entry point and stop it before it turns into structural repair.
