Oskaloosa, the Mahaska County seat, has a good share of older homes, and many of them have brick chimneys that have been doing their job for a long time. Top Notch Chimney Sweep & Services serves Oskaloosa with chimney sweeping, inspections, repairs and relining, plus certified dryer vent and air duct cleaning. We’ve been at this since 2002.
The Liner Is the Part That Protects Your House
Inside most masonry chimneys is a flue liner, often clay tile in older homes. The liner contains heat and smoke and keeps them away from the brick and the wood framing around the chimney. It also gives the smoke a smooth, properly sized path to get out.
Over decades, liners take a beating. Heat cycles, moisture, acidic byproducts from burning and the occasional chimney fire can crack tiles and erode mortar joints. A damaged liner can let heat reach combustible materials and let carbon monoxide escape into the house. The trouble is, you can’t see any of it from the fireplace or the roof.
Seeing Inside the Flue
We use video camera equipment, including Chim-Scan, to look inside the flue from top to bottom. That’s the core of a Level 2 chimney inspection, and it’s how we find cracked tiles, gaps and blockages that a flashlight would miss. You’ll get a clear explanation of what we saw.
Fixing a Damaged Liner
If the liner is damaged, chimney relining restores a safe path for smoke and gases. We’ll recommend the right approach for your chimney and the appliance it serves. Relining is also often needed when someone switches from one type of heating appliance to another, since the old flue may not be sized right for the new one.
With clay tile, a brand-new liner isn’t always the first step. We’re certified to install HeatShield®, a refractory sealant that can fill cracked joints, resurface a worn flue or bond a reinforced sleeve inside the old tiles. When full replacement makes more sense, stainless steel liners work with every fuel type and come with a lifetime warranty when professionally installed.
Brick and Mortar on Older Oskaloosa Homes
The outside of an older chimney tells its own story. Mortar joints wear down faster than the brick around them, and once they start to crumble, water gets in more easily. We fix that by tuckpointing, which means removing the failing mortar and packing in fresh.
Spalling is the other common issue: the face of a brick flakes or breaks away after water inside it freezes. Spalled bricks can be cut out and replaced. Our team has trained in Traditional Historic Masonry Restorations at the Campbell Center for Historic Preservation, which helps when a chimney is old enough that the repair should suit the original work. See minor masonry repairs.
Freeze, Thaw, Repeat
Mahaska County gets the same winters as the rest of Iowa, and every freeze-thaw cycle works on a chimney a little more. Water that soaks into brick, mortar or a cracked crown expands when it freezes. Over enough winters, that loosens the top courses of brick and opens gaps in the liner. A yearly inspection catches it while the repairs are still small.
Signs an Older Chimney Needs Attention
- Pieces of clay tile or mortar in the firebox
- Chipped or crumbling brick near the top of the stack
- A musty or tar-like smell from the fireplace in summer
- Smoke that won’t draw up the chimney
- A damper that’s rusted in place or won’t close
Any of these means it’s time for a closer look before you light another fire. On an older chimney, small symptoms are often the visible edge of a bigger issue in the liner or smoke chamber, which is exactly what the camera is for.
Buying an Older House in Town
If you’re buying a home in Oskaloosa with a fireplace or stove, the chimney deserves its own inspection. NFPA 211 calls for a Level 2 inspection when a property is sold or transferred, and that includes the camera run through the flue that a general home inspection doesn’t cover. On an older chimney, that’s where the costly surprises tend to be. We work with buyers, sellers and real estate professionals and explain the results in plain terms. Sellers can benefit too: an inspection before listing gives you time to handle a sweep or a small repair before a buyer’s inspector notes it.
Regular Sweeping Still Matters
Even a sound chimney needs regular care. An annual chimney sweeping removes creosote before it becomes a fire hazard and clears out debris and nesting material. Your floors stay covered and dust stays controlled from start to finish, and that’s guaranteed.
The Air You Breathe Indoors
Older homes often have ductwork that hasn’t been cleaned in years, if ever. Dust and debris settle in the ducts and get pushed around every time the furnace or air conditioner kicks on. Our certified air duct cleaning uses a HEPA vacuum system and specialized brushes to pull that buildup out instead of stirring it into your rooms.
Wood Heat, Gas Logs and What Each Needs
A wood-burning fireplace or stove needs regular sweeping to remove creosote, along with an inspection of the liner, smoke chamber and firebox. Gas logs don’t leave creosote, but the burner, pilot, valves and venting still need checking, and vented logs depend on a clear flue. If you’ve converted an old wood fireplace to gas, the liner deserves a look too, since gas exhaust behaves differently in a flue sized for wood.
Best Time to Book
April through August is our off-season, and appointments are easiest to get then. It’s also the right weather for masonry and liner work, so anything we find can be fixed before heating season. Fall and winter fill up with urgent calls. If you’ve noticed something during the burning season, though, don’t wait for summer. Stop using the fireplace and call us so we can find the earliest date that works.
Dryer Vents Belong on the List
Lint gets past the trap and builds up inside the dryer duct. A clogged duct makes the dryer run longer, wastes energy and raises the risk of fire, and with a gas dryer it can keep exhaust from leaving the house. Our certified dryer vent cleaning clears the line and checks it for damage. It’s easy to pair with a chimney visit to your Oskaloosa home.
Experience Matters on Old Chimneys
Older chimneys can be quirky. Tom Hunkele, who has run the company since 2002, is a Past President of the National Chimney Sweep Guild and a Certified Master Chimney Technician, and his crew includes a Certified Chimney Professional and a CSIA Certified Chimney Sweep. We’ve spent 24 years working on chimneys of every age across Central Iowa.
We serve neighboring Pella and New Sharon too.
