How we fit a chimney cap in Mission Bay
Measure the tile, not the hole
For a cap that clamps onto a flue tile, the outside size of the tile matters more than the opening inside it. Tile walls vary in thickness, and a cap sized to the inside of the flue can end up too small to slide over. Rectangular tiles also need both sides measured.
We take those measurements on the roof during the free inspection. Where the tile is chipped, out of square or wrapped in old mortar, we note it, because that changes the fit. The estimate lists the sizes we measured, so the cap that arrives is the cap that fits your flue.
Old caps set in adhesive or sealant
Some old caps were set in heavy sealant or mortar instead of being bolted or clamped. Removing them can take patience, and the tile top may come away with them. That is not a reason to leave a failed cap in place, but it is a reason to plan the removal.
We tell you in advance if the old cap looks stuck fast to the tile. The estimate then covers careful removal, cleaning off the old material and any tile repair that turns out to be needed. If the tile does break, we stop and explain the options before continuing, so no extra work happens without your approval.
Lid size and wind-driven rain
Lids come in different sizes relative to the screen beneath them. A lid that barely covers the flue can let wind-driven rain slip under it. A wider lid sheds more of it, provided the open area under the lid still suits the flue.
We look at the lid on your current cap and at the direction the weather usually hits the chimney. If rain has been reaching the firebox despite a cap, the lid size is one of several things we check. The proposal names the lid style and explains why it was chosen for your chimney.
One estimate line per part of the top
A clear cap estimate reads like a short list of separate jobs. The cap has its own line, naming the style, the metal and the screen. Tile repair, crown repair, flue clearing and any flashing work each get their own line, with a sentence on why they are needed.
That layout lets you approve the cap and hold back on the rest, or the other way round. It also shows what is not included, such as a roof section for a roofer to handle. Ask us about any line that reads vaguely. We would rather rewrite it than have you approve work you do not understand.
Parts of the cap job we price separately
- Flue height above the crown
- Lid height and open area beneath it
- Crown cracks noted as a separate item
- Old adhesive cleared from the tile
Chimney cap answers for homes in Mission Bay
Will a new cap stop water getting into the fireplace?
A cap keeps rain out of the flue opening. It cannot stop water that enters through a cracked crown, open mortar joints or failed flashing. If water keeps appearing after the cap is fitted, the entry point probably lies elsewhere and needs its own assessment.
What happens if the flue tile is cracked under the cap?
A cap clamped to a cracked tile may not hold, and the crack can let water into the chimney. We list the damaged tile as its own line on the estimate so you can decide on that repair before the cap goes on.
Are chimney caps covered by a warranty?
Our workmanship warranty covers the installation we carry out. The cap itself may carry its maker's own terms, and we pass those details on with the written record of the work.
