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.

AfterFast, Reliable Chimney Repair Across Midwood
Chimney repair in Midwood usually falls into a few predictable categories: crumbling mortar joints, spalled brick faces, flashing that’s given up after 30 years of salt air, and flues that haven’t been touched since the house burned coal. We see the same failure pattern on the semis and detached Tudors between Avenue J and Avenue P, and we know what it costs to put right before we ever climb the ladder. Call (516) 289-9316 and Wendell or his crew will be at your door with a straight answer and a written quote, no game-playing.
Why Top Hat Chimney Is Midwood’s Preferred Chimney Repair Company
Wendell Pike has been working chimney stacks since 1999, and he’s spent enough time on Midwood roofs to know what the original builders did right and where they cut corners. The homes here were built between the wars, mostly 1920 through 1945, with solid brick but soft lime mortar that has now survived 80 to 100 freeze-thaw winters. That’s not something a national outfit’s sales rep fresh from training is going to spot from the driveway. It’s the difference between a $400 repoint and a $4,000 rebuild, and the camera footage we show you tells which one you actually need.
Ask anyone on your street. Wendell lives in the same region he works, puts his name and license number on every estimate, and backs every job with a 90-Day Done Right Promise in writing. If it isn’t right, one phone call brings the crew back at no charge. No voicemail, no call center. A live person answers around the clock, and it may well be Wendell himself.
Our Chimney Repair Services in Midwood
Every Chimney Repair job starts the same way: we look, we photograph, and we give you a plain-English verdict. Here’s what that covers most often on Midwood blocks.
Mortar Repointing
Midwood’s semi-detached brick homes were built with lime-rich mortar, which moves with temperature and gives rather than cracks. But nothing lasts a century, especially within a few miles of Jamaica Bay, where the air carries salt and moisture into every exposed joint. Repointing in Midwood typically runs $18 to $32 per square foot, depending on how deep we have to rake and the access from the roof. We match the original lime mortar composition rather than slapping on hard Portland cement, because mortar that’s too rigid will crack your soft common brick within a few winters.
Spalling Brick Repair
Spalling is what happens when water gets behind the face of an old brick, freezes, and pops the surface off. We see it concentrated at the roofline on Midwood’s two-story semis, where old flashing has rotted and let rain track straight into the brick. A typical spalling repair runs $650 to $1,800 depending on how many bricks are shot and whether we’re working from the roof or a lift. If the face has spalled more than a quarter-inch deep, we’ll tell you honestly whether replacement is the better call.
Chimney Waterproofing
Midwood sits in southern Brooklyn, close enough to the Atlantic that the humidity is often ten points higher than inland neighborhoods. On interwar soft brick, that means efflorescence, slow spalling, and a masonry surface that absorbs water like a sponge once the original surface is gone. We use a breathable siloxane waterproofing treatment that keeps water out while letting trapped moisture escape. A full chimney waterproofing on a typical Midwood two-story runs $450 to $850. It’s one of the only chimney repairs that adds decades of life for hundreds of dollars rather than thousands.
Flashing Repair
Flashing is where most Midwood chimney leaks begin. The galvanized steel the original builders installed was never meant to go 80 years, and the salt air coming off the bay shortens that life further. When galvanized flashing rots out, water gets in at the roofline, soaks the brick, and causes the spalling and mortar failure you see two or three feet below. We replace it with stainless or copper, cut into the mortar joint and sealed with premium sealant, not surface caulk. Flashing repair in Midwood runs $500 to $1,400, and it’s almost always the first step before any internal liner work.

Trusted Brands We Service in Midwood
We install and stand behind components from manufacturers that have proven themselves on Brooklyn chimneys: Gelco caps and chase covers, Olympia Chimney dampers and liners, and Famco rebuild kits. We keep common Midwood parts in stock locally, which means a rusted cap or cracked crown from the salt air doesn’t mean a week of waiting for a part to ship. Most repairs finish same-day once the scope is confirmed.
Common Chimney Repair Problems We See in Midwood Homes
- Corroded caps from salt air. Midwood’s prevailing winds carry bay and ocean air straight across the neighborhood. Galvanized caps rust out in 15 years, and then rain and birds get into the flue. Replace with stainless or Gelco, and the problem’s solved for decades, not years.
- Oversized terra-cotta flues from the coal-to-gas conversion. These homes were built to vent coal, with flues far too large for the 40,000-BTU gas boiler that’s heating them now. The result is draft failure and carbon monoxide pooling, a risk that only a properly sized stainless liner retrofit fixes.
- Party-wall flues with cross-vent problems. In Midwood’s semis, one chimney stack often carries flues for both halves of the building. When the internal wythe between those flues deteriorates, exhaust from one home’s furnace can enter the neighbor’s firebox. A pressure test is the only way to confirm it.
- Freeze-thaw damage to lime mortar. Brooklyn averages more than 30 freeze-thaw events a year, and Midwood’s older brick absorbs winter moisture. Without repointing every couple of decades, the faces start popping. Catch it early and it’s a repointing job. Leave it and you’re into a rebuild.

FAQs - Chimney Repair in Midwood
Salt accelerates metal corrosion and masonry deterioration in two ways: it draws moisture out of the air onto surfaces, and it chemically attacks both steel and lime mortar. Your galvanized cap, which might last 30 years inland, rusts through in 15 here, and your crown develops hairline cracks that widen every freeze. The fix is a stainless cap or a Gelco cap, plus annual inspection. Call (516) 289-9316 and we’ll tell you what’s on your roof today.
Yes, and we’ve confirmed exactly that on Midwood streets. On East 16th Street near Avenue M, we found a 1928 Tudor where a gas water heater had been venting through a cracked shared flue into the adjoining home’s sealed fireplace. Our techs ran a smoke test to confirm the cross-vent, then we sleeved the flue with DuraFlex stainless liner and rebuilt the firebox, cutting off the carbon monoxide risk for both halves. If you suspect this in your semi, call us for a pressure and smoke test before anyone spends money on a liner they may not need.
Once a year, burn or no burn. Chimneys break in the off-season too. Your furnace and water heater are venting through that flue every time they run, and in Midwood’s semis, that flue may be 90 years old, oversized, and cracked in places only a camera will show. A Level 2 inspection with video runs around $250 and it’s the cheapest insurance you’ll ever buy against carbon monoxide.
Because winter is doing the damage and spring is revealing it. Water enters the brick face during late autumn rains, freezes and expands through the winter’s 30-plus freeze-thaw events, and the brick face pops when the ice melts. The damage is done by March, but you notice it in April when you’re out in the yard. Once spalling starts, it accelerates, because each missing brick face lets more water into the wall behind it. The repair is to replace the spalled bricks and waterproof the surface before next winter.
Yes, and we do it regularly. We can sleeve one flue independently of the other, rebuild the shared stack, and run a smoke test to confirm the wythe between the two flues is intact. We coordinate with both property owners when access crosses a property line or a party wall is involved. For an exact written scope, call (516) 289-9316 and we’ll walk the site with you.
Key Takeaways: Chimney Repair in Midwood
- Salt air from Jamaica Bay corrodes caps and flashing faster than inland Brooklyn; stainless steel replacement costs more up front but lasts decades.
- Party-wall flues in Midwood’s semis require smoke and pressure testing; cross-vent between units is a real carbon monoxide risk we’ve documented.
- Mortar repointing runs $18-$32 per square foot; skip the Portland cement, use compatible lime mortar, or your brick will crack.
- Camera inspection and a written quote come before any recommendation; if the flue is fine, we’ll tell you to spend nothing.
