Chimney

6 Questions

The NFPA recommends a chimney inspection at least once a year and cleaning as needed. For most Tampa homeowners who use their fireplace regularly during cooler months, an annual sweep and inspection covers both. Even if you rarely use your fireplace, an annual check is worth it — Florida’s humidity accelerates mortar deterioration, and warm temperatures make chimneys a year-round target for animal nesting and debris buildup.

Creosote is a dark, tar-like residue that forms when wood smoke condenses on the inside of your flue. It builds up in three stages — from light flaky deposits (easiest to brush away) to a thick hardened glaze (the most dangerous and difficult to remove). At any stage, creosote is highly flammable and a leading cause of chimney fires. Regular sweeping removes it before it reaches dangerous levels.

To slow buildup between professional visits, burn only dry, seasoned hardwood and avoid burning cardboard, trash, or treated wood.

Contact us if you notice any of the following:

  • White staining (efflorescence) on exterior bricks
  • Crumbling or missing mortar between bricks
  • Spalling — bricks that are flaking, cracking, or breaking apart
  • Water in the firebox or damp spots on walls near the chimney
  • Smoke backing into the room instead of drafting up the flue
  • Unusual or musty odors, especially after rain
  • A rusted or stuck damper

Do not use your fireplace again until a professional has assessed the situation.

Yes — in Tampa’s wet climate a chimney cap is essential, not optional. A cap sits over the flue opening at the top of the chimney, blocking rain, debris, and animals while still letting combustion gases vent properly. Most caps also include spark arrestor mesh to catch live embers before they reach your roof.

Without a cap, rainwater enters the flue directly and accelerates deterioration of the liner, damper, and firebox. A cap is one of the least expensive chimney components and one of the most effective at preventing costly damage.

Yes, and it’s one of the most popular upgrades we do. A gas insert installed into your existing firebox gives you the look of a real fire with no creosote buildup, no log hauling, and instant on/off control. The conversion requires a gas line connection (coordinated with a licensed gas fitter) and a flue assessment to confirm the existing liner is rated for gas venting. We’ll walk you through every step and what it means for your specific setup.

It does — and in some ways Florida is harder on chimneys than colder climates. High humidity accelerates mortar erosion and metal corrosion inside the flue. Tropical storms and hurricanes can damage caps, crowns, flashing, and masonry. Warm temperatures make chimneys attractive nesting spots for birds and small animals all year long. And because fireplaces are used less frequently here, damage can go undetected far longer than in a home where the fireplace runs every week in winter. Annual inspections are the best defense.

Dryer Vents

6 Questions

Most households should have their dryer vent professionally cleaned at least once a year. If you run multiple loads per day, have a large family, or dry a lot of heavy items like towels and bedding, every 6 months is safer. The longer the vent run — especially if it includes bends or turns — the faster lint accumulates and the more frequently it needs attention.

Watch for these warning signs:

  • Clothes take more than one cycle to fully dry
  • The dryer or laundry room feels unusually hot during a cycle
  • You notice a burning smell while the dryer is running
  • The exterior vent flap barely opens or doesn’t open at all
  • It’s been more than a year since your last cleaning
  • Lint is visible around the dryer vent opening or behind the machine

Any of these signs means you should stop using the dryer until the vent is inspected.

Dryer fires are one of the most common causes of residential house fires in the United States — the U.S. Fire Administration reports roughly 2,900 home dryer fires per year, with failure to clean the dryer vent as the leading contributing factor. Lint is highly combustible. When it builds up inside the vent duct, it restricts airflow and traps heat. The combination of restricted airflow and accumulated lint creates exactly the conditions a dryer fire needs to start.

A clean vent isn’t just about dryer performance — it’s a basic home fire safety measure.

Most dryer vent cleanings take between 30 and 60 minutes. Longer duct runs, multiple bends, or heavy lint buildup can add time. We use professional rotary brush and vacuum equipment to clear the full length of the duct — not just the accessible section near the dryer — and we inspect the duct condition at the same time. The area is left clean when we finish.

You can clean the lint trap yourself after every load — and you should. But the lint trap only catches a portion of what passes through the dryer. The rest travels into the duct and accumulates along the entire length of the run, around bends, and at the exterior vent. Consumer dryer vent brush kits can help with short, straight runs but rarely reach the full duct or clear blockages at bends and joints. A professional cleaning addresses the full system and confirms the duct is intact, properly connected, and venting correctly to the outside.

Beyond clearing lint from the duct, we inspect for a few things that frequently cause problems:

  • Duct material: Flexible plastic or foil accordion duct is a fire hazard and should be replaced with rigid or semi-rigid metal duct
  • Duct length and routing: Excessively long runs or too many bends reduce airflow and increase lint buildup — we flag these
  • Exterior vent flap: The flap should open freely when the dryer runs and close completely when it doesn’t — a stuck or missing flap lets animals and outside air in
  • Connections: Loose joints or disconnected sections can leak lint and carbon monoxide into living spaces

If we find something that needs attention, we’ll tell you clearly what it is and what it takes to fix it.
