Chimney repair and diagnosis in Kingswood Manor

Spark arrestor screens and their size

Some chimney caps carry a mesh screen around their sides. That screen is a spark arrestor, and on a masonry chimney the Florida Building Code lists what it has to meet.

A spark screen only helps while its mesh is open. Soot, creosote or leaves packed into it cut down the opening the smoke has to pass through, which works against the open area the code sets.

Where a screen is clogged, bent or rusted through, our crew checks whether cleaning will do or the cap needs replacing, and whether a replacement is sized for your flue. Screen and cap then share one priced line.

• Its open area is at least four times the open area of the flue outlet
• The screen resists heat and corrosion
• It can be reached and removed so the flue can be cleaned

Loose stones on a stone veneer chimney

Some stone chimneys are built of solid stone, while others carry the stone as a veneer, one outer layer set against a framed or block chimney behind it. A stone that rocks, drops or shows an open joint around its edge has lost its bond to that backing.

Where masonry veneers a frame chimney, the Florida Building Code requires through-flashing and weep holes so water that gets behind the stone can drain back out. A veneer built without them, or with them buried in mortar, has no way to shed that water.

Our stone chimney repair service chooses between resetting stones and taking down a section. On your Kingswood Manor home the estimate names the stones or courses involved and which of these applies.

• A few loose stones on sound, dry backing are reset
• Wet or soft backing behind the stone is repaired first
• Missing flashing at the base means rebuilding that course
• Wide movement across the face points to a section rebuild

The cleanout door at the base of a flue

A small metal door at the bottom of a chimney, outside or in a utility space, is usually a cleanout. The Florida Building Code requires a cleanout opening close to the base of each masonry chimney flue, with a noncombustible cover, so ash and debris can be taken out. Fireplace flues that can be cleaned through the fireplace opening are the exception.

Cleanout doors rust, warp and lose their latches. One that is missing or hangs open gives animals and water an easy way in, and one rusted shut leaves debris sitting at the base out of sight.

Replacing the door is a small job, but the frame has to sit tight in the masonry so the new cover closes properly. The base of the flue is cleared first, then a noncombustible door and frame are fitted. Any of these signs puts the door on the estimate.

• A door that will not latch or close flush
• Rust holes or a warped frame
• Loose mortar around the frame
• Ash or debris spilling from the opening

Turning an inspector's note into a repair plan

Home inspection reports often flag a chimney in general terms. 'Cracking observed at crown', 'flashing appears sealed with caulk' or 'further evaluation recommended' tells you something is off without saying what it takes to fix.

Each note needs to become a named part, a cause and a repair. A crown crack might call for sealing or for a new crown. Caulked flashing might need counterflashing set into the mortar joints. A vague call for evaluation may turn out to cover nothing serious, or a flue that should not be used at all.

Hand our technicians the report and they work through it line by line on the chimney itself. The written estimate then answers each note with the component, what was found and the repair with its price, along with anything the report missed. If a flagged item turns out to be sound, you hear that too.
