Midvale sits in Salt Lake County with a semi-arid climate that brings cold winters and warm summers. Freeze-thaw cycles drive water into brick and mortar joints on chimneys serving homes in Old Town Midvale and around Bingham Junction. Proper waterproofing uses breathable silane-siloxane sealers applied after cleaning and tuckpointing to let moisture escape while stopping liquid penetration. Homes near the Bingham Junction TRAX Station often have 1950s-1970s construction with single-wythe chimneys that crack faster when water freezes inside the flue.
Applying waterproofing too early on new mortar or over failing crowns leads to trapped moisture and spalling. We inspect the crown, flashing, and cap first, then address any gaps before sealing. West Jordan and Murray share the same winter conditions, so the same approach works when we cross into those areas, but Midvale's older stock in Old Town requires extra attention to soft mortar that absorbs more water during spring thaws.
Edge cases include chimneys with metal liners where sealant must stop short of the liner to avoid corrosion, and homes on sloped lots near Midvale City Park where wind-driven rain hits one side harder. We never seal over active leaks or efflorescence without first fixing the source. Work is scheduled around dry windows in our variable spring and fall weather to ensure the product cures properly.
Technician insight
In Midvale, the thing that catches most people out with chimney waterproofing is applying sealer over soft mortar in Old Town homes without first tuckpointing. Our cold winters turn that trapped moisture into spalling within one freeze-thaw cycle, especially on chimneys facing the prevailing winds off the valley.
Old Town Midvale Chimney Leak
Water was entering around the crown on a 1960s brick chimney in Old Town Midvale. Inspection showed open mortar and a hairline crown crack allowing meltwater to reach the attic. We repointed the joints, repaired the crown, then applied waterproofing. No further staining appeared after the next winter storms.
