Holladay sits in Salt Lake County with a semi-arid climate that swings from hot summers to long cold winters carrying heavy snow. Many homes in Holladay Village, Mount Olympus, and Cottonwood were built decades ago with brick chimneys that lack modern flashing or crown seals. Snow piles on roofs near Olympus Hills Park and Holladay City Park, then melts and refreezes, forcing water through cracked mortar and porous brick. Without waterproofing, this leads to interior staining, rusted flue liners, and eventual structural failure that shows up first in attics during spring thaw.
Proper waterproofing starts with removing old sealant and loose debris, then applying a breathable masonry sealer rated for freeze-thaw cycles common here. We also address the chimney crown and step flashing where water enters most often on homes near Millcreek and Cottonwood Heights. Older Salt Lake County chimneys often have terra-cotta flues that shift slightly each winter, so sealants must remain flexible rather than crack. Skipping the crown or using non-breathable products traps moisture inside the masonry and accelerates spalling the following season.
Access matters in this terrain. Steep driveways and narrow lots around Mount Olympus require careful ladder placement and sometimes roof anchors to reach the chimney safely. We check for existing code-compliant spark arrestors and ensure any new waterproofing does not block draft. Homeowners in Holladay frequently discover issues only after water stains appear on ceilings, so annual inspections before first snow remain the practical step to avoid larger repairs later.
Technician insight
In Holladay, the thing that catches most people out with chimney waterproofing is how quickly snow melt from the north-facing slopes around Mount Olympus re-freezes in the crown joints. Older brick homes here expand and contract enough each winter that a rigid sealant fails within two seasons, letting water reach the flue liner before homeowners notice.
Mount Olympus Chimney Leak
Water stains appeared on the ceiling after a heavy March snow. We found cracked crown mortar and failed flashing on a 1970s brick chimney. New flexible sealer was applied to the crown and step flashing, and the masonry was coated with breathable waterproofing. No further leaks occurred the next winter.
How it works
- 1
Site Inspection
We examine the crown, flashing, and brick joints from the roofline on Holladay properties, noting snow load patterns and prior repairs.
- 2
Surface Preparation
Loose mortar and old coatings are removed so the new sealer bonds directly to sound masonry.
- 3
Crown and Flashing Treatment
A flexible, breathable sealant is applied to the crown and step flashing to block meltwater entry points common after Salt Lake County winters.
- 4
Full Chimney Sealing
Masonry sealer is rolled or sprayed across all exposed brick and mortar, then allowed to cure before the first freeze.
Pricing
Pricing varies by chimney height, access, and existing condition; we provide upfront quotes after inspection.
