Fast, Reliable Chimney Cap & Crown Across Hollis
Last March we pulled up to a cape on Coburn Road where the crown had cracked clean through after another brutal freeze-thaw cycle. The homeowner had watched water seep into the flue all winter, assuming it was “just condensation.” By the time we arrived, the lime mortar had turned to sand and three flues were exposed to the weather. That’s a familiar sight in Hollis. We’ve been repairing chimney caps and crowns here since 1984, and we’ve learned that southern New Hampshire’s extended heating season and violent spring thaws punish masonry harder than most homeowners expect. A chimney cap and crown in Hollis typically runs $280-$750 for standard repairs, with most jobs completed in a single visit. Call (844) 803-1545 - a live person answers, even at 10 p.m. on a Sunday.
Why Hearthstone Chimney Co. Is Hollis’s Preferred Chimney Cap & Crown Company
Hollis isn’t a town you serve well from a distance. The lots are large, the driveways are long, and many homes sit back from roads like Nashua Street and Silver Lake Road with chimneys you can’t properly assess from the ground. We’ve been driving these roads for over 42 years. Russell Haines started this company in 1984, and our technicians know the difference between a 1780s center-chimney colonial near the historic village and a 1985 suburban colonial off Route 122. That matters because the repair approach is entirely different.
Our reputation in Hollis is built on showing up when we say we will and documenting what we find. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. The 90-Day Done Right Promise backs every job in writing - if it’s not right, we make it right, no paperwork and no arguing. Calls are answered by a live person 24 hours a day, 7 days a week. Most of our Hollis customers are referrals from neighbors who’ve had us out for Chimney Cleaning & Sweep in Hollis and learned their crown was failing during the same visit.
Our Chimney Cap & Crown Services in Hollis
Cap Installation
New cap installation in Hollis starts around $340-$580 for a standard single-flue stainless steel unit with proper screen mesh. Many of the older colonials near the town center have multiple flues clustered on one stack, which is where our Chimney Cap & Crown team often recommends a multi-flue cap instead. These cover the entire crown, directing water off the masonry rather than just shielding individual flue openings. For homes on wooded lots off Pine Hill Road or Beaver Brook Road, we size the screen to keep out the heavy leaf and needle load that Hollis properties generate.
Cap Replacement
We replace a lot of caps in Hollis that were installed by roofers or homeowners who didn’t understand chimney dynamics. A cap that sits too low traps moisture. A screen that’s too fine clogs with creosote. We see both problems regularly in the 1975-1995 suburban builds, where original caps have rusted through after decades of service. Replacement runs $280-$520 depending on flue count and access. We carry Gelco and Olympia Chimney caps on our trucks, so most Hollis replacements happen same-day without a return trip.
Crown Repair
Crown repair is our most common spring call in Hollis, and there’s a reason. March and April bring the freeze-thaw cycles that shatter lime-mortar crowns on the town’s original masonry stacks. A proper crown repair - not a caulk job, but formed concrete or specialized crown coat - runs $450-$780. We also evaluate whether the flue liner beneath needs attention; many of these old chimneys were never lined for modern appliances. When that’s the case, we’ll recommend Chimney Liner & Rebuild in Hollis before we seal a crown over a compromised system.
Crown Coating
For crowns with minor cracking but sound structural integrity, we apply HeatShield CrownCoat or similar professional-grade flexible sealants at $320-$480. This isn’t a permanent solution for a crown that’s already crumbling, but it’s the right call for early-stage deterioration on a well-built crown. We schedule these most often in late April and May, after the final freeze has passed and before the summer humidity sets in. The coating needs dry conditions to cure properly, and Hollis’s spring window is narrow enough that we keep flexible scheduling for these jobs.

Trusted Brands We Service in Hollis
We don’t use builder-grade materials. Our trucks carry professional-grade caps and crown repair products from Gelco, Olympia Chimney, and Famco - brands that hold up to Hollis’s weather, not just the first season. Gelco’s stainless multi-flue caps come with lifetime warranties against rust-through. Olympia Chimney’s screening is sized to handle the creosote load we see from green-wood burning without clogging. Because we stock these on our service vehicles, most Hollis customers don’t wait for parts orders. The cap goes on the same day we diagnose the problem.
Common Chimney Cap & Crown Problems We See in Hollis Homes
- Crown cracks from freeze-thaw cycling. Hollis’s March temperature swings - often 20 degrees in a single day - force moisture into hairline cracks, where it expands overnight and widens the gap. By April, a crown that looked sound in October can be shedding chunks. We inspect for this specifically during spring cleaning appointments.
- Multi-flue stacks with no cap coverage. The historic colonials near the village center frequently have two or three flues serving original fireplaces and long-disconnected heating appliances. Without a full-width cap, rain enters the unused flues and erodes the interior masonry. We regularly install custom multi-flue caps on these stacks.
- Rust-through on original galvanized caps. The suburban wave of 1975-1995 construction often included cheap galvanized caps that last 15-20 years in Hollis’s climate. We’re now in the replacement cycle for many of these homes, particularly in neighborhoods off Route 130 and Middle Road.
- Crown wash failures from DIY repairs. We find a surprising number of Hollis crowns coated with standard mortar or caulk by previous owners. These trap water rather than shed it, accelerating deterioration. Proper crown material is formulated to flex and breathe; anything else is a temporary fix that makes the eventual repair more expensive.

Hollis prices are in line with our southern New Hampshire rates overall. The main variable is access - Hollis’s larger lots and longer driveways sometimes add modest travel time, but we do not surcharge for location. A single-flue cap installation costs the same in Hollis as it does in Nashua. The bigger price difference comes from housing stock: Hollis’s older, multi-flue masonry chimneys often need more extensive crown work than the simpler stacks common in newer Merrimack subdivisions.
Every cap and crown job is backed by our 90-Day Done Right Promise in writing - if it’s not right, we make it right, no paperwork and no arguing. Beyond that, manufacturer warranties apply: Gelco and Olympia Chimney stainless caps carry lifetime rust-through coverage. Crown repairs with formed concrete include our two-year workmanship guarantee against material failure. We document every job with photos so there’s never a question about what was done.
