We are having issues with water entering into the house during driving rains because of compromised (old) mortar in the chimney. Thus, we are having our chimney sack washed (its seems like the only answer according to our contractor).

At that point, we would want our whole house one color. Its a two story house (3200 square feet).

We were given 2 priceS:

Sack wash whole house and chimney-23k (the plus is it secures the mortar for the whole house).

13400 to mortar chimney then paint rest of the house.


My question is what is the typical life span of painted brick vs mortar wash in southeast LA?

How old is the mortar? Sure it’s not the flashing? You can tuck and seal the mortar

Do not rush into this approach. I know the stress/aggravation of a water leak in a house.

Has the brick been sealed with siloxane?

There is a difference between sacking brick and tuck pointing.

Have you had anyone other than this contractor look at it?

I have old brick and mortar on my chimney also and it was leaking any time it rained. I bought a chimney brick sealer for $100 on Amazon and sealed it myself and it no longer leaks.
