You have probably seen them: those hairline fractures, maybe a spiderweb pattern, or even a more significant crack stretching across your stucco. If you live in Salt Lake City, you know our homes take a beating, and Stucco is no exception. It is not just about making things look good again; it is about protecting your biggest investment from what our local weather throws at it in Salt Lake City.

Here in the Salt Lake Valley, we have a climate that is very tough on exterior finishes. We are talking about those intense UV rays from our high altitude, massive temperature swings – sometimes 40 degrees in a single spring or fall day – and those brutal freeze-thaw cycles all winter long. This constant expansion and contraction of materials is a major reason for Stucco damage in Salt Lake City. Add in our expansive clay soil, which shifts as it gets wet and dries out, and you have a perfect storm for Stucco cracks.

Why Our Salt Lake City Climate Makes Stucco Repair Tricky

Salt Lake City Stucco & Plastering has seen it all in our years. What works for Stucco Repair in a humid coastal town just will not cut it here in Salt Lake City. Our dry air, high elevation, and temperature extremes mean Salt Lake City Stucco & Plastering has to approach Stucco Repair differently.

  • UV Degradation: That intense sun we get all summer in Salt Lake City? It breaks down Stucco finishes faster than you would think. Elastomeric coatings, which might last 15 years elsewhere, often only get a 10-year warranty here in Salt Lake City because of the strong UV rays.
  • Freeze-Thaw Cycles: This is a very important one for Stucco in Salt Lake City. Moisture gets into tiny cracks in the Stucco, freezes, expands, and then thaws, pushing the Stucco apart. It is a relentless process that causes a lot of the deeper Stucco issues we see.
  • Rapid Temperature Swings: Stucco is rigid, but it still moves. When the temperature drops 30 degrees overnight in Salt Lake City, that Stucco material is under serious stress.
  • Alkaline Soil: You might not think about the dirt around your house in Salt Lake City, but our alkaline soil can contribute to efflorescence, that white powdery substance, especially if your Weep Screeds are not doing their job for your Stucco.

Common Stucco Problems Salt Lake City Stucco & Plastering Sees Around Town

Whether you are in a charming 1970s home in Sugar House or a newer build out in Daybreak, certain Stucco issues pop up consistently for Salt Lake City Stucco & Plastering:

  • Hairline Cracks: These Hairline Cracks are often just cosmetic, especially if they are thinner than a sixteenth of an inch and do not run in a straight line. Hairline Cracks are common around windows and doors where there is natural stress on the Stucco. Salt Lake City Stucco & Plastering can usually seal these Hairline Cracks up with a flexible caulk.
  • Larger Cracks: If you have Stucco cracks wider than an eighth of an inch, or ones that run diagonally from corners, or even a stair-step pattern, those are warning signs for your Stucco. These Larger Cracks can point to movement in the framing or foundation, or worse, water getting behind the Stucco.
  • Moisture Intrusion: This is the silent killer for Stucco. Even in our dry climate in Salt Lake City, if water gets behind the Stucco because of failed Flashing, bad caulking, or overflowing gutters, it can cause serious damage to the Stucco substrate and even rot. High moisture readings are a very big red flag for Stucco Moisture Intrusion.
  • Delamination or Spalling: This is when the Stucco starts to separate from the wall or flake off. Stucco Delamination or Spalling is often a sign of long-term moisture issues or improper Stucco installation.
