Chimney Services in Crown Point, IN
Seven services, grouped by the problem they solve, with a plain guide to choosing the right one before you call.

Clean and check: the two visits every chimney needs
Sweeping removes flammable deposits and inspection judges whether the structure is sound; NFPA 211 calls for the inspection every year. Chimney sweeping and cleaning removes what burning leaves behind. Wood smoke condenses on the flue walls as creosote, and it comes in three stages: a dusty soot that brushes away, crunchy black flakes that need a stiffer rotary head, and a shiny tar glaze that has to be broken down chemically or mechanically. Each stage burns hotter than the last if it ignites, which is the whole reason for sweeping before the deposit thickens.
Chimney inspection answers a different question: is the structure sound? A Level 1 inspection covers the readily accessible parts of a chimney that has been used the same way for years. Level 2 adds a video scan of the flue interior plus the attic, crawl space and other accessible areas, and it is the one NFPA 211 calls for when a property changes hands, an appliance is swapped, or the chimney has been through a fire or a storm.
Fix and protect: masonry, liners and the top of the stack
Three services stop water and contain heat: masonry repair on the outside, a liner on the inside, and caps and crowns on top. Chimney repair and masonry work deals with water damage, because nearly every masonry failure in this climate starts with water. Mortar joints erode first; tuckpointing grinds them out and packs new mortar before bricks loosen. Where the stack meets the roof, step flashing and counter-flashing let down into a cut mortar joint keep runoff out of the attic. Spalled bricks, whose faces have blown off after freezing while saturated, get replaced.
Chimney relining gives the flue a new inner wall. Clay tiles crack from a chimney fire or from decades of thermal shock, and once joints open, heat and gases reach the brickwork. A stainless steel liner listed to UL 1777 restores a continuous path, and it also corrects sizing: a flue too large for the appliance drafts lazily and runs cool, which makes more condensation and more creosote.
Caps, crowns and dampers are the roof-level parts that decide how much rain enters. The crown is the slab on top of the masonry; it should slope away from the flue and overhang the brick so water drips clear. The cap sits over the flue opening with a mesh skirt against sparks, birds and raccoons. A top-sealing damper replaces a warped throat damper with a gasketed lid operated from the firebox.
Gas appliances and the other vents in the house
Gas fireplaces, dryer exhaust ducts and furnace ductwork each need their own service, because none of them is cleaned by sweeping a chimney. Gas fireplace tune-ups keep a clean-burning appliance reliable. The pilot flame heats a thermocouple and, on millivolt systems, a thermopile (small heat-powered sensors that prove the pilot is lit); when either weakens, the gas valve drops out and the fire will not stay lit. Service covers those parts, the burner ports, log placement, the glass gasket and the vent or termination cap.
Dryer vent cleaning is a fire-prevention job more than a housekeeping one. Lint that escapes the screen settles wherever airflow slows: elbows, sags in flexible duct, and the exterior hood flap. The residential code section on dryer exhaust, IRC M1502, caps the run at 35 feet with deductions for each elbow, and an over-length run clogs far sooner.
How to choose the right service
Choose a chimney service by the fuel you burn and the symptom you see, then let an inspection confirm it. If you would rather talk it through, call (219) 203-9797.
Start with what you burn
Cordwood means creosote, so sweeping and inspection come first. Gas means ignition parts and venting, so a tune-up is the visit. A pellet or wood stove needs its connector pipe and liner cleaned along with the appliance.
Name the symptom, not the fix
Tell us “water in the firebox after rain” rather than “I need a cap”. Leaks have at least five common sources and the chimney symptom guide shows how each one presents.
Think about what changed
A new furnace, a new insert, a home purchase or a lightning strike each change what the chimney must do. Any of them is a reason to ask for a Level 2 inspection instead of a routine sweep.
Combine visits where it makes sense
A sweep plus Level 1 inspection is the standard pairing. Dryer vent cleaning adds little time while the equipment is already at the house.
Check the starting price, then call
Figures for all seven services are kept on the pricing page and nowhere else, so there is one number to refer to when we talk.
Not a scheduling matter
If a carbon monoxide alarm is sounding or you smell gas, leave the house first and call 911 or your gas utility from outside. Chimney service comes after the emergency is handled.
Choosing between chimney services
Which chimney service should come first after buying a house?
A Level 2 inspection. NFPA 211 specifies that level on the sale or transfer of a property because the new owner has no history of how the fireplace was used or maintained, and a camera pass is the only way to see the flue joints.
Is a chimney sweep the same thing as a chimney inspection?
No, a chimney sweep and a chimney inspection are different jobs. Sweeping removes deposits; inspecting evaluates condition. They are usually done together because a flue coated in soot cannot be examined properly, and a flue that has just been cleaned is the best time to look at the tile.
When does a chimney need relining instead of repair?
When the damage is inside the flue rather than on the outside. Cracked or missing clay tiles, eroded joints between tiles, or a flue mismatched to a new appliance are liner problems. Loose exterior brick, bad flashing and a cracked crown are repair problems.
Do I still need a cap if the crown is in good shape?
Yes, a chimney needs a cap even when the crown is sound. The crown sheds water off the masonry around the flue, but the flue opening itself is a hole in the roof. Without a cap, rain falls straight down it, and animals treat it as a hollow tree.
Can several services be handled in a single visit?
Often, yes: several chimney services can share one visit. Sweeping, a Level 1 inspection and dryer vent cleaning fit together naturally. Masonry repair and relining are usually scheduled separately because they depend on what the inspection finds and, for mortar work, on the temperature.
Does a gas fireplace need service if it burns clean?
It does. Gas leaves little soot when adjusted correctly, but pilot assemblies foul, thermocouples weaken, spiders nest in burner orifices and glass gaskets flatten. A unit that produces soot on the logs or glass is telling you its air-to-fuel mix is off.
What is the difference between tuckpointing and a crown rebuild?
Tuckpointing renews the mortar joints between bricks on the sides of the chimney. A crown rebuild replaces the slab on the very top. They fail for the same reason, water and frost, but they are different parts and different repairs.
Can I book just an inspection without a sweep?
Yes. A Level 1 or Level 2 inspection can be booked on its own, for a home sale, after a chimney fire, or when you want the flue checked before the first fire of the season. If the inspection finds the flue is dirty enough to hide problems, we will say so before any sweeping is added to the visit.
Not sure which service fits? Describe the problem by phone.
Tell us what you burn and what you have noticed. We will name the visit that fits.
