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.

AfterMortar Repointing in Brooklyn, NY
Mortar repointing in Brooklyn typically runs between $400 and $1,800 depending on how much of the chimney needs attention, and in most cases we can complete the work in a single visit. If you’ve noticed crumbling joints, white staining on your brick, or gaps wide enough to catch a finger, the mortar is failing – and that failure only moves in one direction without repair.
Wendell Pike has been doing this work in Brooklyn since 1999. He’s seen what happens when homeowners let failing mortar ride another winter, and he’s also seen plenty of jobs where a neighbor was sold a full rebuild when a careful repoint was all the chimney needed. That’s not how we work. When you call (516) 289-9316, you get an honest look at what’s actually going on – not a pitch for the most expensive option on the board.
Mortar repointing is exactly what the name says: the old, deteriorated mortar between your chimney’s brick or stone courses gets removed, and fresh mortar is packed back in to restore a watertight, structurally sound joint. It sits under our broader Chimney Repair in Brooklyn umbrella, and it’s one of the more common repairs we handle across neighborhoods from Flatbush to Bay Ridge to Crown Heights. Brooklyn’s freeze-thaw winters are hard on mortar. The good news is that catching it early is far cheaper than rebuilding the courses it eventually destroys.
When You Need Mortar Repointing
Mortar deteriorates slowly, which means homeowners often don’t notice a problem until it’s become a bigger one. Here are the clearest signs that your Brooklyn chimney needs repointing:
- Joints that are visibly recessed or crumbling. Run your finger along the mortar lines – if the joint sits more than a quarter inch back from the brick face, or if mortar comes away in chunks or powder, it’s time. We see this constantly on pre-war row houses in Park Slope and Bed-Stuy, where original mortar has been in place for eighty or ninety years.
- Efflorescence – that white, chalky staining on the brick. It means water is moving through the masonry and carrying mineral salts to the surface. The mortar joints are usually where it’s getting in.
- Brick faces that are chipping or spalling. Once water infiltrates through deteriorated joints and freezes inside the brick, the face of the brick itself starts to pop off. At that point you’re dealing with more than a repointing job – but catching the mortar early prevents it from getting there.
- Water stains on the ceiling or upper walls near the fireplace. In Brooklyn’s older housing stock, a leaking chimney often gets mistaken for a roof problem. If the staining tracks near the chimney chase, the mortar joints are worth checking before you call a roofer.
- A chimney inspection report flagging deteriorated mortar. If a CSIA-certified sweep has run a camera and flagged joint deterioration, take it seriously. What starts as a surface problem can undermine brick courses within a few seasons if Brooklyn winters keep doing their work.
- It’s been more than 25 years since the chimney was last repointed. Mortar has a lifespan. On a chimney that sees regular use in a Brooklyn climate, 20 to 30 years is a reasonable service window. If you don’t know when the last repoint happened, that’s worth finding out.
Our Mortar Repointing Process
A repointing job done right isn’t just filling gaps. The prep work matters as much as the new mortar, and cutting corners on it is how you end up with fresh joints that fail in three years instead of twenty. Here’s how Wendell and his crew handle it:
- Visual inspection and joint mapping. Before any tools come off the truck, we walk the chimney – from the firebox and smoke chamber up through the flue to the crown – and note every section where mortar has deteriorated. We separate cosmetic wear from structural failure. Not every joint needs the same attention, and honest scoping saves you money.
- Old mortar removal. We cut or grind out the deteriorated mortar to a minimum depth of three-quarters of an inch, usually closer to an inch on joints that have gone soft all the way through. This is the step that separates a proper repoint from a surface patch. Skim-coating over failing mortar looks fine for a year and then falls out, taking new mortar with it. The right depth gives fresh mortar the mechanical grip it needs to last.
- Joint cleaning. Once the old mortar is out, we brush and blow the joints clear of dust and loose material. We also wet the brick lightly before packing new mortar – dry brick pulls moisture out of fresh mortar too fast and weakens the cure.
- Mortar matching and application. Mortar mix matters more than most homeowners realize. Modern Portland-heavy mixes are harder than the brick on older Brooklyn buildings, and when a hard mortar and a soft brick expand and contract at different rates, the brick loses – it cracks or spalls while the mortar stays put. We match the mortar type to the masonry. On older soft-brick buildings, that usually means a lime-based mix. We work in lifts on deep joints to prevent shrinkage cracking.
- Tooling and finishing. Once the mortar has set to leather-hard, we tool the joints to match the original profile – usually a concave or weathered joint on Brooklyn-area chimneys. This isn’t just cosmetic; the tooling compresses the mortar surface and sheds water more effectively.
- Final inspection and cleanup. We check every joint we’ve touched, clean mortar smear off the brick face, and walk you through what we did and why. If we spotted anything else during the job – crown cracking, flashing separation, a damaged cap – we’ll tell you about it plainly and let you decide what to do next. No pressure either way.
Mortar Repointing Pricing in Brooklyn
Mortar repointing in Brooklyn runs between $400 and $1,800 for most residential chimney repair jobs. A chimney that needs two or three courses repointed around the crown costs far less than one where the entire exposed stack has open joints. Here’s a general breakdown of what affects where your job lands in that range:
| Scope of Work | Typical Range (Brooklyn) |
|---|---|
| Minor repointing – crown area and a few courses | $400 – $650 |
| Partial repointing – upper half of the exposed stack | $650 – $1,100 |
| Full chimney repointing – all exposed exterior joints | $1,100 – $1,800 |
| Repointing plus crown repair or cap replacement | $1,400 – $2,400 |
A few things push a job toward the higher end: difficult roof access on a Brooklyn row house or brownstone, taller chimneys that require staging, brick that’s eroded badly enough to need individual replacement alongside the mortar work, and jobs where we find interior smoke chamber mortar that also needs attention.
Any repair over $200 qualifies for our $40 off standing offer – no coupon code needed, just mention it when you call. Seniors and veterans always get 10% off the total job. And if you’ve already gotten a written estimate from another company and it felt off, our free second opinion is exactly that – we’ll look at the scope, tell you honestly whether it seems right, and let you make the call without any pressure.
Upfront pricing is how we operate. The number we quote you on the phone is the number on the invoice when the job is done. Wendell doesn’t send someone to your door to discover new problems after you’ve agreed to a price.
FAQs – Mortar Repointing
How is repointing different from tuckpointing?
Repointing and tuckpointing are often used interchangeably, but they’re not quite the same thing. Repointing means removing deteriorated mortar and replacing it with fresh mortar – the goal is structural repair and weatherproofing. Tuckpointing is a finishing technique where a thin line of contrasting mortar is applied to give the impression of very thin, precise joints; it’s more of a cosmetic treatment than a structural fix. Most Brooklyn homeowners need repointing, not tuckpointing. If someone quotes you tuckpointing on a chimney with genuinely deteriorated joints, make sure they’re also doing the removal and repack work, not just surfacing over the problem.
How much does chimney mortar repointing cost in Brooklyn?
Most Brooklyn chimney repointing jobs fall between $400 and $1,800 depending on how many courses need attention, how high and accessible the chimney is, and whether any brick replacement is required alongside the mortar work. For a detailed breakdown, see How Much Does Chimney Repair Cost? (2026 Price Guide) - Brooklyn, NY. A partial repoint of the upper stack – the most common scenario we see in Flatbush, Windsor Terrace, and similar neighborhoods – typically runs $650 to $1,100. Call (516) 289-9316 for a free estimate. We quote upfront and we don’t change the number at the door.
Can I wait another season before repointing?
Sometimes, and sometimes not – it depends on how far along the deterioration is. Mortar that’s worn but still present and sitting at roughly a half inch of recession is probably fine to monitor through one more winter. Mortar that’s crumbling out, allowing water into the joint, or leaving gaps visible from ground level should not wait. Brooklyn’s freeze-thaw cycle – where temperatures can swing above and below freezing dozens of times between November and March – forces water deeper into open joints every time it cycles. A joint that’s borderline in October can be actively spalling brick by April. If you’re not sure which category you’re in, a quick inspection from Wendell will tell you plainly. No charge for the honest answer.
Will new mortar match my existing brick color?
It will get close, and usually close enough that you won’t notice unless you’re looking for it. Fresh mortar always cures a bit lighter than aged mortar, but it weathers down over a season or two. On the structural side, mortar type matters far more than color – we match the mortar composition to the brick hardness, which is especially important on the older soft-brick row houses and brownstones common across Brooklyn. We use quality materials sourced through suppliers like Gelco and Olympia Chimney to get consistent results. If you want a precise cosmetic match on a historically sensitive building, we can discuss pigmented mixes – just let us know when you call.
