Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Cap & Crown Across St. George
Chimney cap and crown repair in St. George, NY typically runs $340-$890 depending on whether you’re replacing a corroded cap, sealing crown cracks, or rebuilding from the flue up. Most jobs we book in St. George are completed in a single visit, with materials stocked for harbor-specific corrosion issues we see nowhere else on Staten Island. Call (516) 613-3035 for a free estimate - we’ll give you a straight number and a date.
We’ve been dispatching crews to St. George from our New York City office for decades. We know the late-Victorian row houses on the harbor slope, the coal-era chimneys that were never properly lined, and the way a nor’easter can peel a galvanized cap back like a sardine tin. Our Chimney Cap & Crown technicians are background-checked, uniformed, and carry the professional-grade materials to fix it right - DuraFlex, HeatShield, Gelco, and the stainless hardware that actually survives here.
Why Hearthstone Chimney Co. Is St. George’s Preferred Chimney Cap & Crown Company
St. George homeowners call us because we’ve earned a reputation for saying what needs to be said and fixing only what needs fixing. Over 42 years, we’ve built that reputation one chimney at a time - no shortcuts, no upsells, just documented work with photos you can see and a plain-English verdict.
Our reviews from St. George customers consistently mention the same things: we show up when we say, we explain the problem without talking down, and we leave the job site cleaner than we found it. One customer on St. Mark’s Place told us she’d fired two other companies for pushing a full rebuild when all she needed was a crown coating and cap swap. We photographed the cracks, coated the crown, set a stainless cap, and she hasn’t had a leak since.
Response time to St. George is typically within a few days of booking, sometimes sooner depending on weather windows. We coordinate dispatch from our New York City office, but our crews live and work across Staten Island - they know Richmond Terrace from Bay Street and which blocks catch the worst harbor wind.
That local knowledge matters. A cap that works in Great Kills can fail in St. George in half the time. We know which chimneys face the harbor directly, which sit in the wind shadow of the hill, and where the freeze-thaw cycling hits hardest. That specificity saves you money and keeps water out.
Our Chimney Cap & Crown Services in St. George
Cap Installation
New cap installation in St. George starts around $340-$520 for a standard single-flue stainless model, with custom caps running higher depending on dimensions and mesh specs. We measure on site, fabricate or order to fit, and install with proper storm collars and screening. On harbor-facing stacks, we specify 304 or 316 stainless - never galvanized - because we’ve seen too many rust-through failures on St. George’s salt-air chimneys.

Cap Replacement
Cap replacement is our most common call in St. George, and for good reason. The galvanized caps installed by builders and previous owners simply don’t hold up to New York Harbor exposure. We regularly pull caps off St. George chimneys that have rusted through on the harbor side while the landward side still looks presentable. Replacement with stainless runs $380-$620 including removal and proper sealing. If the crown beneath is cracked, we’ll tell you before we start and price the repair together - no surprises on the bill.

Crown Repair
Crown repair in St. George addresses the concrete or mortar wash that tops your chimney and sheds water away from the flue. Harbor-driven rain and freeze-thaw cycling open hairline cracks into full radial breaks that let water straight into the masonry below. We grind out damaged material, apply a bonding agent, and rebuild with professional-grade crown mix or flexible coating depending on the extent of damage. Typical range: $450-$780. Severe cases requiring full rebuild run $680-$890. Every crown repair includes a photo report and our 90-Day Done Right Promise in writing.

Crown Coating
For crowns with early cracking but sound structure, crown coating is a preventive fix that extends service life five to ten years. We clean the surface, fill active cracks, and apply a flexible, breathable sealant formulated for coastal freeze-thaw conditions. In St. George, where crowns take more thermal stress than inland chimneys, this treatment pays for itself by deferring rebuild costs. Runs $340-$480.

Custom Cap
Multi-flue chimneys, oversized flues, and decorative pots require custom caps measured and fabricated to order. We work with Copperfield and Famco for St. George’s custom jobs, with typical lead times of one to two weeks. Custom caps start around $520 and run to $1,200+ for complex copper or multi-flue designs with integrated dampers. We template on site, confirm dimensions with you, and install with the same no-surprise pricing.

Trusted Brands We Service in St. George
We stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes, no hardware-store specials. For St. George’s salt-air environment, that means stainless caps and crowns with proper coastal ratings, not galvanized steel that’ll rust through in three seasons. We keep common stainless cap sizes and crown coating materials on our trucks, so most St. George jobs don’t wait on parts. When custom work is needed, we order direct from the manufacturer and track it ourselves - you don’t chase deliveries.
Common Chimney Cap & Crown Problems We See in St. George Homes
- Galvanized caps rust through on the harbor-facing side first. Salt-laden air off New York Harbor corrodes steel faster than an inland Staten Island chimney ever sees. We see this on Richmond Terrace and the blocks facing the ferry terminal most often - the cap looks fine from the street, but the harbor side is paper-thin.
- Hairline crown cracks open into full radial cracks from nor’easter wind-driven rain and repeated freeze-thaw cycling. Water enters, freezes, expands, and splits the crown wider each winter. North-facing stacks on the harbor slope take the worst of it.
- Step and counter flashing pulled loose by coastal wind lifts, opening gaps where water enters the brickwork and accelerates spalling on harbor-exposed stacks. We’ve found flashing gaps on St. George chimneys that had been leaking for years before the homeowner noticed interior damage.
- Coal-era flues with thimble connections, never properly lined, compound cap and crown problems by allowing exhaust gases and moisture to condense inside the chimney, accelerating mortar deterioration from the inside out. This is endemic to St. George’s attached row houses and requires a Level-2 camera inspection to assess fully.

FAQs - Chimney Cap & Crown in St. George
Salt-laden air off New York Harbor accelerates steel corrosion by a factor of three to five compared to inland Staten Island neighborhoods. The harbor-facing side of a galvanized cap on a St. George chimney can rust through in three to five years, while the same cap in Great Kills might last twelve to fifteen. We specify 304 or 316 stainless for every St. George replacement. Call (516) 613-3035 if you’re unsure what material is on your chimney now - we can check during a free estimate.
Every twelve months for harbor-exposed chimneys in St. George, and every eighteen months for those in the wind shadow of the hill. The salt air, wind-driven rain, and freeze-thaw cycling here punish crowns faster than inland climates. We include crown condition in every Level-2 inspection, with photos you can see. If you’re due, call (516) 613-3035 for a seasonal check.
We grind out loose or spalled material, assess the structural integrity of the remaining crown, apply a bonding agent formulated for freeze-thaw conditions, and rebuild with professional-grade crown mix or flexible coating. On St. George’s hardest-hit chimneys, we may recommend a full rebuild with enhanced slope and overhang to shed harbor rain more aggressively. Typical crown repair runs $450-$780; full rebuilds run $680-$890. We photograph before, during, and after, and back it with our 90-Day Done Right Promise.
Only if the chimney serves multiple appliances or fireplaces with separate flues. Many St. George row houses have a single flue adapted from coal to oil or gas, so a standard single-flue cap is correct. But some multi-family conversions and larger Victorians do have two or three flues in one chimney stack, and a multi-flue cap with proper partition walls prevents cross-drafting and keeps rain out of all flues. We determine this during inspection - never guess from the ground. Call (516) 613-3035 and we’ll sort it out.
Yes. Coastal wind in St. George lifts step flashing and opens counter-flashing joints where you can’t see them from below. We’ve found active leaks on chimneys whose owners swore the flashing was sound, because the gap was on the harbor side, two courses up, visible only from the roof. Our Level-2 inspection includes close-up photos of flashing condition. If it’s sound, we say so. If it’s not, we show you exactly where it failed. Estimates are free - call (516) 613-3035.
