Our approach to chimney waterproofing in Colonialtown South

Two parts of the job our chimney specialists explain to homeowners in Colonialtown South before any product is applied.

Waiting for fresh mortar to cure

New mortar holds a lot of water while it cures, and sealing it too early can interfere with that process. The Brick Industry Association calls for freshly repointed joints to cure at least 72 hours before a coating goes on, and SaverSystems sets the same minimum for its chimney product after repairs or tuckpointing.

When your chimney needs joint work and waterproofing, we schedule them as two steps. The mortar goes in first, the cure time passes, and then we come back for the treatment once the surface is also dry enough for the product. Both visits appear on one estimate, so the plan is clear from the start.

Where a silane product fits

Silanes are smaller molecules than siloxanes, so they can penetrate dense surfaces well. They react fastest on alkaline materials such as concrete and concrete block, and products meant for brick often add a catalyst to help them cure on the less alkaline clay.

On a concrete block chimney or a dense cast top section, a silane or a pre-blended silane and siloxane product may be the better match. We read the maker's substrate list before choosing and never mix products on site. A pre-blended product keeps the proportions the manufacturer tested.

Keeping rain off a fresh application

SaverSystems tells users of its water-base chimney repellent not to apply it when rainfall is expected within six hours unless the surface is protected with polyethylene film or its equivalent. Rain on a fresh coat can wash product off before it has taken hold.

We check the forecast the day before and again that morning. When a storm is likely to roll in, we either set up protection or move the date. Our family team would rather call you to reschedule than spray a treatment the weather will rinse off by evening.

Sealant where masonry meets other materials

Where masonry meets metal, wood or siding, a flexible sealant usually fills the joint. When that sealant cracks or pulls away, water runs straight into the gap. Masonry guidance lists replacing failed sealant among the repairs a repellent should not replace.

On a chimney, those joints can be around a cricket, at the counterflashing or where a chase meets brick. We check them during the inspection and replace failed sealant as a separate item. The masonry repellent then handles what it is made for, which is the water the brick and mortar absorb.

Asked in Colonialtown South about chimney water repellent

Still deciding? These answers help, and the inspection in Colonialtown South is free.

Can you waterproof a painted chimney?

Usually not with a penetrating repellent. Products like these are made for bare masonry, and makers say not to apply them over paint or glazed brick. We look at the paint's condition and tell you honestly whether to leave it, repair around it or plan something else.

Can you waterproof a stucco or stone chimney?

Often, yes, with a product whose maker lists that surface. Stucco cracks and loose stone joints get repaired first. We follow the product's instructions for that material and treat a test area where the result is uncertain.
