Question DetailsAsked on 8/16/2017

How much is it to get my chimney sealed and capped?

I have some bricks on my chimney sloughing off. My insurance company said it needs to be sealed and capped. How much is that and what is involved?

Do you have the same question? Follow this Question

I am surprised they did not ask for repointing of the brick too - just sealing will do little or nothing to brick that is already sloughing off - plus sealing brick is actually very bad for it if not internally or back-face ventilated (as chimneys generally are not) because it seals in the water that is going to get in there through cracks and such.

Anyway, sealing and capping by a Mason or some Chimney Sweeps who also do minor repairs - probably about $100-250 for the sealing depending on whether just the above-roof part or entire chimney exterior surface to the ground, capping (just taking off the chimney cap and screening and replacing with a domed sheet metal cap) usually about $100 on same trip.

Be sure to get a receipt/invoice which shows SPECIFICALLY that they "sealed chimney" and "capped chimney" to provide to the insurance company, so it exactly matches the terminology of what the wanted done.

You can find other previous questions about repointing both entire exterior part of chimney, and also just above-roof portion (which generally goes a lot earlier) - see the Home > Chimney link under Browse Projects, at lower left.
