Chimney Sweeping & Cleaning
How often should a chimney be swept?
The National Fire Protection Association recommends an annual inspection, with sweeping as needed based on creosote buildup — typically once a year for regular wood-burning fireplaces.
Does sweeping make a mess in my house?
A properly done sweep shouldn't leave any soot in your home. We seal the work area and use vacuum containment before opening the flue.
Chimney Inspection
What's the difference between Level 1 and Level 2?
Level 1 is a basic visual check for a chimney with a known service history. Level 2 adds a video scan of the flue and is required for real estate sales, after an appliance change, or after any event that could have damaged the system.
Can I get an inspection without a sweep?
Yes — inspection and sweeping are billed and scheduled separately, though we'll flag it if your flue needs a sweep to properly complete the inspection.
Chimney Repair
How do I know if my chimney needs repair or just cleaning?
Cracks, water damage, and mortar loss need repair; soot and creosote buildup need cleaning. An inspection is the fastest way to tell which one you're dealing with.
Is chimney repair covered by homeowners insurance?
It depends on the cause and your policy — sudden damage (like a lightning strike) is more commonly covered than gradual wear. We can provide documentation for a claim either way.
Chimney Relining
How long does a chimney liner last?
It depends on material and use, but a properly installed stainless steel liner typically lasts 15-25+ years with regular maintenance.
Do all chimneys need a liner?
Modern building codes require one, and even older unlined chimneys benefit significantly from adding one — both for safety and appliance efficiency.
Chimney Cap Installation & Repair
Will a chimney cap reduce draft?
A correctly sized cap has minimal impact on draft — it's an oversized or poorly designed cap that causes problems, which is why proper sizing matters.
Can a chimney cap stop animals from getting in?
Yes — a cap with a mesh screen is the standard way to keep birds and animals out while still allowing smoke to vent.
Chimney Crown Repair
What's the difference between a chimney crown and a chimney cap?
The crown is the concrete/masonry surface covering the top of the whole chimney structure. The cap is the smaller cover, usually metal, that sits over the flue opening itself. Both matter, but they're different components.
Can a cracked crown really cause that much damage?
Yes — water entering through crown cracks can freeze and expand in winter, accelerating masonry damage throughout the chimney, not just at the top.
Masonry & Rebuilding
Does a leaning chimney need to be fully rebuilt?
Not always — it depends on the extent of foundation or structural movement. An inspection determines whether repair or full rebuild is the right call.
What is tuckpointing?
Tuckpointing is removing deteriorated mortar from between bricks and replacing it with fresh mortar, which restores both the structural integrity and appearance of the chimney.
Chimney Waterproofing
Will waterproofing trap moisture inside the chimney?
Not if the correct vapor-permeable sealant is used — this is the whole point of using a purpose-made masonry water repellent instead of a generic sealant.
How long does waterproofing last?
Most treatments are rated for 5-10 years, depending on product and exposure.
Dryer Vent Cleaning
How often should dryer vents be cleaned?
Annually for most households, more often for larger families or households that do frequent laundry.
Is this the same as cleaning the lint trap?
No — the lint trap only catches a portion of lint. The rest accumulates in the ducting itself, which is what this service addresses.
Fireplace Repair & Installation
Can you install a fireplace where there wasn't one before?
Yes, in many cases — factory-built units with their own venting system can often be added without a traditional masonry chimney. We'll assess your home's layout.
Do you repair gas fireplaces too?
Yes, for the firebox, venting, and mechanical components — gas line and appliance-specific work may involve coordination with a licensed gas technician.
Wood Stove Installation
Can a wood stove use an existing fireplace chimney?
Often yes, with a properly sized liner connecting the stove to the chimney — this is a common and effective setup.
Do wood stoves need a permit?
Many jurisdictions require one — we can advise on local requirements as part of planning the installation.
Gas Fireplace Service
How often should a gas fireplace be serviced?
Annually is standard, similar to a furnace, even though gas units don't produce creosote the way wood-burning ones do.
Why is my gas fireplace flame uneven?
This is often a burner or ignition component issue, sometimes related to dust/debris buildup — an inspection will identify the specific cause.
Animal & Bird Removal
Is it safe to just remove the nest myself?
Not recommended — some species (like chimney swifts) are federally protected, and improper removal can be both illegal and unsafe.
Will a cap definitely keep animals out for good?
A properly fitted cap with mesh screening is the most effective long-term prevention, yes.
