Measuring, choosing and fastening a chimney cap
Count the flues before pricing a cap
Some chimneys carry one flue and some carry two or more, often at different heights. From the yard, a double chimney can look like a single one. The count changes the job, because separate caps on each flue and one large cap over all of them are different installations.
We count and measure every flue during the free inspection. Where one flue serves the fireplace and another serves a different appliance, each keeps the termination its own appliance calls for. The estimate then shows whether we propose single caps, a multi-flue cap or a mix, with the reason written next to each.
Open area under the lid and the draw
A rain cap sits over the flue with open sides beneath its lid. The Florida Building Code sets a minimum for that open area, in proportion to the flue outlet the cap serves. A cap that is too small or sits too low can narrow the path the smoke has to take.
We size the cap against the flue it covers, not against the width of the chimney. Where one cap covers several flues, each flue still needs its own clear path out. If your fireplace smoked after an earlier cap was fitted, mention it when you call. That history tells us where to start looking.
Enough crown for a multi-flue cap
A crown-mounted cap needs a flat, sound area on the crown for its flanges. The maker's guidance keeps the flanges back from the crown edge, so a narrow crown can leave too little room. Cracks, patches and a sloped surface can also make the flanges sit unevenly.
We measure the crown around the flues and check where each flange would land. If the space is tight, we look at other styles or a made-to-measure base. Where the crown needs repair before it can hold a cap, that repair is listed on its own line, with the cap priced separately.
A cap that did not match its flue
Some caps simply did not match their flue when they were fitted. A cap that is too small may perch on the tile with bolts at full stretch. One that is too large may lean, leave gaps at the corners or catch the wind.
We compare the existing cap with the flue it sits on and tell you whether the fit was ever right. If it was not, we measure properly and propose a cap that matches the flue. Tell us if the old cap came from a store and was fitted without measuring. That history often explains why it failed.

Asked about chimney cap replacement in Princeton
Will you need to drill into my chimney crown?
Only for caps that mount on the crown. Their flanges are fastened into the crown and kept back from its edge so the concrete does not crack. Caps that clamp to a flue tile or band around the brick need no drilling there.
Do you clean up after replacing the cap?
Yes. We take away the old cap and its hardware, clear debris from the roof area and haul it off. If the flue has to stay open overnight for any reason, we cover it at the end of the work day.
Can you replace just the screen on my cap?
Where the maker offers a replacement screen and the rest of the cap is sound, that can be enough. A piece of generic mesh is not the same thing, because the opening size affects both sparks and draft.
