Old leak repairs

Some leaking chimneys already carry patches: roof cement over the flashing, silicone on the crown, a coat of paint or clear sealer on the brick. Each was an attempt to stop a leak, and each can now hide where the water really gets in.

When the O'Neil chimney has that history, old patches come off in the test zones so the materials underneath can be judged and wetted properly. Taking them off is a job of its own. Testing through a layer of tar would only tell us about the tar. If water is coming in right now in O'Neil, call (904) 920-5495 on the 24/7 line.

The county for O'Neil is Nassau County. The coast is close to O'Neil.

Read, test, fix, recheck

Attic stains and readings
We read the stain pattern on the rafters and take moisture readings on the chimney breast before any water goes on.
Water test by zone
Flashing, faces, crown and flue are each wet on their own for a set time while someone watches inside.
Fix at the proven entry
The part that let water in gets the repair, whether that is flashing, a crown coating, a cap or repointed joints.
Dry-out and a storm check
Wet areas are noted for drying, and after the next heavy rain we check that the stain stays dry.

Storm season leaks in O'Neil

Between June 1 and November 30, heavy rain and wind arrive together. A leak that shows only in those storms may never appear under a garden hose.

In O'Neil we test what can be tested, write down what could not be reproduced, and suggest a second targeted test if a storm brings the leak back.

For O'Neil leak repairs, the 10% discount is printed apart from the price, so you see it come off.

Reading the chimney breast with a moisture meter

A moisture meter pressed against drywall or plaster shows how wet the material is behind the paint, long before a stain appears. We take readings on the chimney breast and the wall or ceiling around it before any test water goes on, then again after each zone.

A reading that climbs after a zone is tested points at that zone even if no drip appears. Readings also help after the repair: a breast wall that dries back to the level of the walls around it is good evidence the leak has stopped, and it tells you when the surface is dry enough to repaint.

Flooding the crown with the flue covered

To test the crown on its own, the flue opening is covered so no water can run down the liner, and a gentle flow is run across the top of the crown for a set time. Water that gets into cracks in the crown, or around the flue tile where there is no bond break, drops into the core of the chimney.

Because that water has farther to travel, crown leaks can take a while to appear inside. We watch the attic and the firebox for longer on this zone, and we note how long it took, because a delayed result is itself a sign of water moving through masonry.

Holes drilled into the chimney for mounts

Satellite dishes, antennas, lights and gutter brackets get fixed to chimneys because the masonry is solid and convenient. Every anchor drilled into brick or a mortar joint is a new path for water, especially when the fixing sits on the face that takes the weather.

We look for old and current mounts, check whether the holes were sealed, and test those areas along with the face around them. Abandoned mounting holes get filled with mortar or a suitable sealant, and working mounts can often be moved to a spot that does not pierce the chimney at all. Each hole is recorded by face.

Leak questions from O'Neil

Will the water test make my leak worse?

The test puts water where rain already goes, in controlled amounts, and we stop a zone as soon as water shows inside. We protect the area below the leak with towels or a tray. Any water that comes in is much less than a storm would bring.

Does the 10% discount apply to leak work?

It does. Leak tracing and repair booked within 72 hours of the inspection come 10% off like any other job. Bring it up on the call.
