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.
Famco Crown Repair: The Lawrence Owner’s Guide
Famco crown repair in Lawrence typically runs $350 to $700 installed, depending on how much of the existing crown can be saved and which Famco-compatible crown system matches your flue tile. We keep the common Famco crown sizes on the truck, so most Lawrence jobs are done in a single visit. The way most homeowners find the problem is plain: they see a crack from the ground, notice water staining on the ceiling near the chimney, or a home inspector flags it before a sale. A cracked crown lets water sit on the masonry, and in Lawrence that means freeze-thaw cycles working the crack wider every winter.

If you’ve got a Famco crown that’s split, spalled, or pulling away from the flue, you’re in the right place. This page tells you exactly what we see on Lawrence chimneys, what it costs to fix, and when you can leave it alone.
Which Famco Models This Applies To
Famco makes cast-in-place chimney crown forms and pre-cast crown caps in a handful of standard dimensions. Most Lawrence homes with a single flue take a crown sized between 16 by 16 inches and 24 by 24 inches, with an outside drip edge that overhangs the brick by at least two inches. The gotcha we run into regularly: the flue opening in a Famco crown is sized for standard 8-by-8 or 13-by-13 clay tile, and if your chimney has a stainless liner, the opening needs a trim collar or a field cut. Rushing that fit leaves a gap that birds and rain find within a season.
We use genuine Famco crown forms when the job calls for a poured crown, and we’ll tell you plainly when a quality aftermarket pre-cast crown does the same job for less money. The decision usually comes down to flue size and whether the existing crown can be salvaged. Top Hat Chimney is an independent local shop, not affiliated with Famco, but we’ve installed enough of their crowns to know which series fits which chimney. If you can read the model number off the old crown or measure the flue tile, we can confirm the right part before we even schedule the truck.
Signs Your Famco Crown Repair Is Failing
- Hairline cracks running across the crown surface. Water gets in, then freezes. In Lawrence, a hairline crack in November is a quarter-inch gap by March. The crown is the chimney’s roof, and a cracked roof leaks.
- Pieces of crown material in the gutter or on the roof. That’s called spalling, and it means water has been working through the crown for a while. Once the surface starts shedding, the damage accelerates.
- Water staining on the ceiling near the chimney chase or on the firebox walls. Not every stain traces to the crown, but when the stain shows up after rain rather than after a fire, the crown is the first suspect. We camera the flue to confirm before recommending anything.
- Efflorescence on the brick below the crown. That white powdery residue is minerals leaching out of the masonry. It tells you water is moving through the brick, and on Lawrence chimneys the crown is the usual entry point.
- The crown has pulled away from the flue tile or shifted off-center. A crown that’s no longer seated properly lets water run straight down the outside of the flue. This is common on older Lawrence chimneys where the original wash-and-cap was never a true poured crown.
Replacement Cost & What’s Included
For a standard single-flue chimney in Lawrence, a Famco crown repair with a new poured or pre-cast crown lands between $350 and $700. The spread depends on three things: whether we can reuse the existing form or need to build a new one, how much of the old crown needs to be removed, and whether the flue tile needs any repair before the new crown goes on. The price we quote on the phone is the price on the invoice. No fuel charges, no surprise add-ons. And as always for Lawrence customers, repairs over $200 carry the $40 discount, and seniors and veterans take 10% off. Every crown job is covered by our 90-Day Done Right Promise: if it’s not right, one call brings Wendell back.
DIY or Call Us?
A crown repair is not a high-tension or high-voltage job, but it is a roof-height job, and the roof is the last place to learn the difference between a stable footing and a bet. Older Lawrence chimneys often have steep pitches and aged flashing, and the crown itself can be loose enough that putting weight on it breaks more than it fixes. If you want to check yours from the ground with binoculars, go ahead: look for cracks, missing pieces, and any proud silicone patches from a previous owner. But the repair itself needs a ladder, the right crown mix, and a clean, smooth pour. Wendell and his crew have done enough of these on Lawrence rooftops to know the wind off Jamaica Bay doesn’t wait for you to steady your trowel. Call (516) 604-2573 and we’ll give you a straight answer on what yours actually needs.
FAQs
A properly poured Famco crown on a Lawrence chimney should last 15 to 20 years before it needs serious attention. The freeze-thaw cycles near the water shorten that, especially if the crown was poured too thin or without a proper drip edge. If it’s clean, I’ll tell you it’s clean. Schedule an inspection and we’ll tell you exactly where yours is in that lifespan.
A hairline crack can be sealed and we do that often, but a crown with multiple cracks, spalling, or separation from the flue is beyond patching. The repair works when the crown is otherwise sound and the crack is narrow enough to clean and caulk. Call (516) 604-2573 and we’ll tell you which camp yours falls into, based on what we can see from the roof.
Most crown replacements take one visit, usually three to five hours from setup to cleanup. We remove the old crown material, inspect the flue tile, set the form or pre-cast crown, and pour. The crown needs to cure, but that doesn’t keep you waiting: the chimney can handle a fire again within a few days. We’ll give you a straight answer on timing when we see the job.
We keep the most common Famco crown sizes and forms on the truck, and we also stock compatible crowns from Copperfield when a specific flue size calls for it. If your chimney needs a size we don’t carry, we’ll have it within a few days. Call (516) 604-2573 with your measurements and we’ll check the truck.
