We’ve been working on Arlington chimneys since 1984. Russell Haines started this company with the belief that a homeowner deserves to see what the sweep sees, understand what needs fixing, and pay exactly what was quoted. That hasn’t changed in 42 years. When we drive down Massachusetts Avenue toward a triple-decker in 02474 or pull up to a Queen Anne on Park Avenue in 02476, we’re not guessing at what we’ll find. We’ve seen these chimneys before. The coal-era flues, the oil-conversion patches, the crowns that have been shedding mortar since the Reagan administration. Arlington’s housing stock is a known quantity to us, and that familiarity saves our customers both time and money.
Why Hearthstone Chimney Co. Is Arlington’s Preferred Chimney Cap & Crown Company
Local reputation built on showing our work. In a town where word still travels at the hardware store and the farmers market, we’ve stayed busy for four decades because we document every inspection. Our Level-2 camera work ends with photos you can see and a plain-English verdict. No jargon, no scare tactics, just the condition of your crown and what it’ll take to fix it right.
Reviews from Arlington homeowners. Our customers here mention the same things again and again: the technician arrived when promised, explained the repair without pushing, and the final bill matched the estimate. That’s the 90-Day Done Right Promise in action - in writing, no arguing. If it’s not right, we come back.
Response time that respects your schedule. Arlington is compact, and we keep parts and materials stocked for the typical pre-1940 chimney configurations we encounter here. Most cap and crown calls in 02474 and 02476 are scheduled within 24 hours, and emergency water intrusion or animal entry gets priority same-day service.
Knowledge that only comes with time on local roofs. We know which blocks near Spy Pond see accelerated crown deterioration from wind-driven rain off the water. We know the triple-decker stacks off Broadway often need multi-flue caps sized for flue tiles that don’t match modern standard dimensions. That kind of specificity matters when you’re deciding between a $340 crown coating and a full rebuild.
Our Chimney Cap & Crown Services in Arlington
Cap Installation
New cap installation in Arlington runs $220-$480 for a standard single-flue galvanized or stainless unit, with copper and custom profiles running higher. The triple-deckers near the 02474 center frequently need multi-flue caps covering three or four flue tiles in one assembly, which we fabricate to fit after precise field measurement. A properly fitted cap keeps Arlington’s heavy leaf fall, squirrel population, and wind-driven precipitation out of flues that may already be compromised from decades of fuel-type changes. We install caps from Gelco and Olympia Chimney with stainless hardware that won’t rust out in five New England winters.
Cap Replacement
Cap replacement is one of our most common Arlington calls, especially after the February freeze-thaw cycles have finished cracking rusted galvanized caps from the 1990s. A typical replacement in Arlington costs $180-$420. We remove the failed unit, inspect the flue tile and crown surface beneath it - this is where we often find hidden crown damage the old cap was masking - and install a new cap sized correctly for your flue. If you’re in one of the 02476 bungalows with an original terracotta flue tile, we’ll match the cap to the actual tile dimension, not a nominal standard that leaves gaps.
Crown Repair
Crown repair in Arlington ranges from $280 for crack sealing and waterproofing to $680 for partial rebuilds where the concrete wash has deteriorated significantly. Arlington’s freeze-thaw cycle is brutal on crowns: water enters hairline cracks, expands overnight when temperatures drop into the teens, and progressively fractures the crown from the top down. We see this pattern constantly on the older brick stacks off Massachusetts Avenue and Broadway. Our repair protocol includes removing loose material, forming a proper slope for drainage, and applying a cementitious crown mix or HeatShield CrownCoat depending on the extent of damage. The finished crown sheds water toward the edges, not into the flue.
Crown Coating
Crown coating with a flexible waterproof membrane runs $340-$520 in Arlington and is our recommended preventive treatment for crowns showing early deterioration but still structurally sound. We apply this after thorough cleaning and minor crack repair. The coating bridges small future cracks as the crown continues to age, extending service life by years. For the Victorian-era chimneys in Arlington Heights and the Brattle Street vicinity, where full crown replacement would involve delicate scaffolding and matching historic profiles, coating often represents the most practical preservation approach. We use professional-grade materials from HeatShield and Famco, never hardware-store brush-on products that fail within two seasons.

Trusted Brands We Service in Arlington
We work exclusively with professional-grade chimney materials: Gelco and Olympia Chimney for caps and multi-flue assemblies, HeatShield for crown coatings and refractory repairs, and Famco for specialty flashing and ventilation components. These aren’t builder-grade substitutes ordered online. We stock common Arlington sizes - including the non-standard flue tile dimensions found in pre-1940 construction - so most cap and crown jobs don’t wait on shipping. When a homeowner on Gray Street calls with water dripping into the firebox, we can often have the right cap on the truck and the leak stopped the same day.
Common Chimney Cap & Crown Problems We See in Arlington Homes
- Crown wash cracked and spalled from freeze-thaw cycling. Arlington’s location in the Mystic River watershed means consistent winter moisture followed by hard freezes. The concrete wash on 100-year-old crowns was never formulated for this abuse. We regularly find crowns on Park Avenue and Brattle Street that have lost their slope entirely, pooling water directly above the flue.
- Missing or improperly fitted caps on multi-flue triple-decker stacks. In the dense housing near Massachusetts Avenue, a single exterior chimney often serves three units with separate flue tiles. Only one flue may have a cap, or a cap may be sized for one flue and leave the others exposed. Squirrels, raccoons, and rain enter the open flues, and creosote from one unit can affect draft in another.
- Original coal-era crowns never rebuilt for modern appliances. Many Arlington chimneys still carry the crown that was poured when the house burned coal. Those crowns were sized for hot, fast draft and weren’t designed to accommodate the cooler, wetter exhaust of modern gas inserts or the creosote-producing burn of wood stoves. The mismatch accelerates deterioration.
- Water staining and interior damage from crown leaks misdiagnosed as roof problems. Homeowners in 02474 and 02476 sometimes spend money on roof repairs when the actual entry point is a cracked crown or failed crown-to-flue seal. Our camera inspection distinguishes crown leaks from flashing or roof issues before any work begins.
Pricing for Chimney Cap & Crown in Arlington, MA
Here’s what cap and crown work actually costs in Arlington’s market, based on jobs we’ve completed in 02474 and 02476 over the past two seasons:
| Service | Typical Range in Arlington |
|---|---|
| Single-flue cap installation (stainless/galvanized) | $220 - $480 |
| Cap replacement | $180 - $420 |
| Multi-flue cap (triple-decker, 2-4 flues) | $380 - $720 |

| Partial crown rebuild | $480 - $680 |
| Full crown rebuild with forming | $720 - $1,200 |
What moves a job toward the higher end: accessibility complications (steep roofs, tight alleyways common off Broadway), non-standard flue tile dimensions requiring custom cap fabrication, and hidden deterioration discovered beneath a failed cap that demands more extensive crown work than initially visible. What keeps costs down: catching problems early through routine inspection, which is why we also offer Chimney Cleaning & Sweep in Arlington to identify crown and cap issues before they require rebuilds.
Every estimate is free, detailed, and fixed before work begins. The number on the estimate is the number on the invoice. We also offer $50 off any repair over $250, a permanent 5% senior and veteran discount, and free second opinions on any written estimate you’ve received elsewhere.

Yes, we work across all Arlington ZIP codes, from the triple-decker neighborhoods near Massachusetts Avenue in 02474 to the single-family streets around Arlington Heights and Brattle Street in 02476. The chimney configurations differ - 02474 sees more multi-flue stacks, 02476 more individual Victorian flues - and our technicians arrive prepared for whichever they encounter.
Active water leaking through a cracked crown or missing cap is an emergency in Arlington’s climate. Every freeze-thaw cycle widens cracks and drives water deeper into mortar joints. A crown that could have been coated for $340 in October often requires a $680 rebuild by March. If you see water in the firebox, white efflorescence on exterior brick, or pieces of concrete wash on the ground near your chimney, call now. We’ll assess urgency honestly - some conditions can wait, others shouldn’t.
Arlington cap and crown costs run roughly comparable to Cambridge and Somerville, slightly below downtown Boston rates where parking and access add time. Our pricing is consistent across our service area - we don’t inflate for zip codes. The main variable is your chimney’s actual condition and accessibility, not your address. We’ll give you an exact number after inspection, and our free second-opinion offer means you can compare our estimate against any other written quote with no obligation.
All our cap and crown work is covered by the 90-Day Done Right Promise - in writing, no arguing. If the repair fails or the leak returns within 90 days, we come back and make it right at no charge. Beyond that, material warranties vary by product: Gelco and Olympia Chimney stainless caps carry manufacturer warranties against defects, and HeatShield crown coatings are backed by their own product guarantee when applied per specification. We document every job with photos so there’s no dispute about what was done or when.
