About Chimney Repair
Chimney repair encompasses a wide range of services: tuckpointing deteriorated mortar joints, replacing spalling or cracked bricks, rebuilding damaged crowns, repairing or replacing flashing, relining damaged flues, and in severe cases, partial or full chimney rebuilds. The right repair depends on a thorough inspection to identify the root cause of the damage.
A damaged chimney is more than an eyesore — it's a structural and safety hazard. Water infiltration through cracked mortar or a damaged crown can rot roof framing, damage ceilings and walls, and lead to mold growth. A compromised flue liner can allow carbon monoxide and combustion gases to enter your home. Addressing chimney damage early is almost always less expensive than waiting until the damage becomes severe.
Signs You Need It
- Visible cracks in the mortar joints or brick faces
- Spalling (flaking or crumbling) brick on the chimney exterior
- White staining (efflorescence) on the brick — a sign of water infiltration
- Water stains on the ceiling or walls near the chimney
- Rust stains on the firebox or damper
- Crumbling or missing sections of the chimney crown
- Loose or missing bricks at the top of the chimney
Our Process in Northbrook
Comprehensive inspection
We inspect the full chimney from firebox to crown, including a video scan of the flue liner, to identify all damage and its root cause — not just the most visible symptom.
Written repair estimate
We provide a detailed written estimate explaining what needs to be repaired, why, and what the repair involves — no surprises, no upselling.
Repair execution
Our masons perform the agreed repairs using materials matched to your existing chimney. We match mortar composition and color, and source brick that matches your existing masonry as closely as possible.
Waterproofing and protection
Where appropriate, we apply a professional-grade breathable waterproofing sealant to protect the repaired masonry from future moisture infiltration.
How Pricing Works in Northbrook
Every chimney is different, so we don't quote service prices over the phone. A registered & insured technician comes out for a $69 inspection visit, inspects everything, and gives you an exact written price on-site before any work begins. If you approve the work, the $69 is deducted from your final bill.

Frequently Asked Questions
Most chimneys can be repaired rather than replaced. A full rebuild is typically only necessary when the structural integrity of the chimney is compromised — for example, when the chimney is leaning, when the brick is severely deteriorated throughout, or when a rebuild is more cost-effective than extensive repairs. Our inspection will give you an honest assessment.
Yes — chimney-related water infiltration is one of the most common causes of interior water damage in older homes. Water can enter through a cracked crown, failed flashing, deteriorated mortar, or a missing chimney cap and travel down the flue or through the masonry into your attic, walls, and ceilings.
We typically schedule service in Northbrook within the same week. For urgent situations — such as a chimney fire, active leak, or carbon monoxide concern — we prioritize same-day or next-day appointments. Call 773-900-4838 to check current availability.
