Chimney questions, answered

Most households here light the first fire in late October, and the calendar at every location fills quickly from mid-September on. If you burned through last winter, the ideal window for a sweep is late spring through August, when the creosote is dry, the schedule is open, and any repair we find can be finished before the first cold night in the Smokies. Call or contact the location nearest you to set a date.

Once the deposit on the flue wall reaches roughly an eighth of an inch, it is time to sweep. Third-stage creosote, the shiny black glaze that forms when green wood or a smoldering overnight fire cools in the flue, is the type that ignites, and it is common in homes that heat mainly with wood. A camera look during the inspection tells us which stage you have.

A Level 1 visual check covers a fireplace that is used the same way every year. A Level 2, which adds a camera scan of the full flue, is the standard for a home purchase, a new insert or furnace connection, or after a chimney fire or lightning strike, and it is the report Tennessee insurance adjusters typically ask for on a claim. A Level 3 is reserved for concealed damage. Every level comes with dated photos.

Each National Chimney Pros location is open Monday through Saturday from 9:00 AM to 5:00 PM and closed on Sunday. Inspections, sweeps, and masonry work are all scheduled by appointment through the location, so call or use the contact form and the staff there will find a date that works for you.

East Tennessee summers keep masonry damp for months, and brick that stays wet loses its face when the first hard freeze arrives in December. Humidity also feeds efflorescence, the white crust that signals water moving through the wall, and it turns old creosote acidic enough to eat clay tile joints. That is why we favor vapor-permeable repellents and lime-compatible mortars over products that trap moisture inside the brick.

Yes. The National Chimney Pros location in Sevierville handles a steady share of overnight-rental cabins, where a stone fireplace may see a fire every night from October through March with a different guest each week. We recommend a sweep and Level 1 inspection before the fall rental season and can coordinate access with a property manager. A photo report after each visit gives owners something to keep on file.

Draft problems in this area usually trace back to one of a few things: a damper that is not fully open, a cold flue on an exterior wall, a liner that is too large for a new insert, or a tightly sealed house with a range hood or dryer running. Tall trees on a mountain lot can also push wind down the stack. An inspection sorts out which one you have before anyone recommends a fix.

Look for shards of clay tile in the firebox, a smoky smell in humid weather, or an inspection camera that shows open joints or missing sections of tile. Older brick houses across Knoxville and Morristown were often built with no liner at all. Any of those findings means combustion gases can reach the wood framing, and the chimney should not be used heavily until it is relined.

It depends on what the inspection turns up. A routine sweep is a set price, while masonry, relining, and leak repair are quoted after we have seen the chimney. In every case you receive a written quote with photos before work is scheduled, and the price on that quote is the price you pay unless you approve a change.

Sudden damage such as a chimney fire, a lightning strike, or a limb through the crown during a storm is often covered. Gradual deterioration from weather and age generally is not. The photo report from a Level 2 inspection documents what happened and when, which is what adjusters need, and we are glad to talk through the findings with your agent.

We do. Our technicians sweep and inspect open masonry fireplaces, wood stoves, fireplace inserts, and factory-built units, and we service vented gas logs and gas fireplaces along with the flue behind them. Wood stove inserts are common in older homes and mountain cabins here, and they need a properly sized liner and a yearly sweep just like an open hearth.

Yes. Masonry repairs, relining, and installations carry a workmanship warranty, and the written quote states what is covered and for how long before you approve it. If something we built does not perform the way it should, call the location that did the work and we will come back and look at it.

Call the nearest location during business hours or send a message through the contact form on this site. A staff member will confirm the date and a morning or afternoon window, and the technician arrives at the scheduled time with the equipment for that job. Inspections and sweeps are usually completed in a single visit.

Every National Chimney Pros technician is CSIA-trained and works from the same inspection checklist, and each location is licensed and insured. Masonry is handled by masons who learned the trade, not sweeps filling in. We are glad to explain our training and standards when you call the location nearest you.
