The short answer

Chimney repair fixes the parts that keep water out and move exhaust safely: mortar, bricks, crown, cap, flashing, damper and flue liner. If you notice water in the firebox, white staining, brick flakes, smoke smells or poor draft, stop using the fireplace or appliance and have the chimney inspected before the next fire.

A chimney takes a beating in New York. Freeze-thaw cycles crack mortar, rain works into gaps around the crown and flashing, and years of exhaust wear down the flue lining. Small problems usually stay quiet until they show up as a damp firebox, a stained wall or a smoky room. EmberGuard Chimney Sweep repairs masonry chimneys, flues, crowns, caps, dampers and flashing for homeowners in New York and nearby cities. Our certified technicians look for the cause, not just the symptom. They explain what they found and what the repair involves before any work begins. The goal is a chimney that keeps water out, vents safely and holds up through the next heating season.

Signs you need chimney repair

Most chimney damage starts small and on the outside, where it's hard to see. These are the signs homeowners usually notice first. If you see any of them, stop using the fireplace or stove until the chimney has been checked.

  • Water in the firebox, or damp spots on the ceiling or wall next to the chimney, especially after rain or snowmelt
  • White, chalky staining on the brick, which means water is moving through the masonry
  • Brick flakes, crumbled mortar or pieces of flue tile collecting in the firebox
  • A smoky or tar-like creosote smell in the room, often stronger in humid weather
  • Poor draft: smoke rolling into the room, fires that are hard to start, or a stove that won't burn cleanly
  • Scratching, chirping or nesting noises in the flue, which usually point to a missing or damaged chimney cap
  • A rusted damper that won't open or close fully
  • Cracked or leaning masonry, or gaps where the chimney meets the roof

What our chimney repair service includes

Every repair job starts with an inspection so the work matches the actual problem. Depending on what we find, a repair visit can include any of the following.

Before we start, we walk you through the findings with photos or camera footage. We also explain which items need attention now and which can wait.

  • Inspection of the chimney exterior, crown, cap, flashing, firebox, damper and flue
  • Camera inspection of the flue when the lining can't be seen from the top or bottom
  • Repointing: removing failed mortar and replacing it with new mortar matched to the existing joints
  • Replacing cracked, spalled or loose bricks
  • Repairing or rebuilding the chimney crown and sealing cracks
  • Installing or replacing a screened chimney cap to keep out rain and animals
  • Resealing or replacing flashing where the chimney meets the roof
  • Repairing or replacing the damper
  • Repairing firebox brick and joints
  • Relining the flue when the original lining is cracked or the appliance has changed
  • Cleanup and a written summary of the work done

How our crew works inside your home and on the roof

Inside, the crew lays drop cloths from the door to the fireplace and covers the hearth and nearby furniture. We seal the fireplace opening and run HEPA vacuums during any work that disturbs soot or debris, so dust stays out of your room. If the flue needs cleaning before repairs, we use rotary brushes sized to the flue. Then we run a camera through it to check the liner, joints and smoke chamber.

On the roof, technicians work only when weather and access make it safe. We protect the roofing around the chimney, keep mortar and debris contained, and haul away old materials. For rowhouses and homes with tight or shared roof access, we plan the approach ahead of time.

When we finish, we vacuum the work area, remove the drop cloths, and check the damper and draft with you.

The standard we follow

Our work follows NFPA 211, the national standard for chimneys, fireplaces and vents. It calls for these systems to be inspected once a year.

Chimney professionals use three inspection levels. Level 1 is for chimneys where nothing about the system has changed. Level 2 is called for when the system changes, such as a new appliance or a switch of fuel, or when the home is sold. Level 3 is needed when a hidden hazard can only be reached by opening part of the chimney or building. We recommend the level that fits your situation and explain why.

If a New York City building is converting its boiler from oil to gas, the chimney has to be evaluated as part of that work. A new liner is often needed, because gas exhaust produces acidic condensate that can corrode a masonry flue. We can inspect the flue and reline it as part of the conversion.

New York City's heat season runs from October 1 through May 31. Late spring and summer are the easiest times to schedule repairs that take a heating system out of service.

What affects the price

Every chimney is different, so we price repairs after the inspection. These are the main factors.

You get a written estimate before repair work begins. If we find something new during the job, we stop and talk with you before doing anything extra.

  • Chimney height and roof access, including roof pitch and number of stories
  • Fuel type, such as wood, gas or oil, which affects which liners and dampers are suitable
  • Flue size, shape and condition, and whether a new liner is needed
  • How much creosote or soot buildup has to be removed before repairs can start
  • Whether a camera inspection or a Level 2 or Level 3 inspection is required
  • The extent of masonry, crown or flashing damage and the materials needed to match it

How a visit works

When you contact us, we ask what you've noticed, what the chimney serves (a fireplace, stove, furnace or boiler) and how the roof is reached. That helps us send the right crew and equipment.

On the first visit, a certified technician inspects the chimney, takes photos or camera footage, and explains what's wrong and what it will take to fix it. Simple repairs, such as replacing a cap or fixing a damper, can often be done the same day. Larger jobs like rebuilding a crown, repointing or relining are scheduled separately.

After the work, we clean up, show you before-and-after photos, and leave a written summary. That gives you a record for your next annual inspection or a future home sale.

FAQ

Common questions

Don’t see your question? Call (472) 287-7082 and we’ll talk it through.

Can I keep using my fireplace while I wait for a repair?

If you see water in the firebox, falling flue tile, smoke entering the room or signs of animals in the flue, stop using it until the chimney has been inspected. Damaged flues and blocked chimneys can let heat, smoke or exhaust go where they shouldn't.

Is white staining on my chimney brick a problem?

White staining means water is passing through the masonry and leaving minerals behind. The stain itself is mostly cosmetic, but the water causing it can crack bricks and mortar over time. We find where the water is getting in, which is often the crown, cap or flashing.

How long does a chimney repair take?

Small repairs like a new cap or a damper fix can often be finished during the inspection visit. Repointing, crown rebuilding and relining take longer and depend on the chimney's size, roof access and the weather.

Do I need a new liner if my building switches from oil to gas?

Often, yes. In New York City, the chimney has to be evaluated when a boiler converts from oil to gas. Gas exhaust produces acidic condensate that can corrode a masonry flue, so a new liner is frequently needed.

How often should my chimney be inspected?

The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. A more detailed inspection is recommended when you change appliances or fuel, sell the home, or suspect a hidden problem.

Can you repair a chimney in winter?

Many repairs can be done in cold weather, but some masonry work depends on temperature and dry conditions. Roof work also depends on safe access. We'll tell you what can be done now and what is better scheduled for warmer months.
