Protect Your Exterior From Weather Damage

Stucco installation and repair services for homes and businesses in Ontario, California

Stucco provides a durable, weather-resistant finish that holds up well in the dry heat and occasional rain common across Ontario. Over time, even well-applied stucco can develop cracks from settling, impact damage, or moisture infiltration, and these openings allow water to reach the underlying structure. Left unaddressed, small cracks widen and let water seep behind the surface, which can damage framing and insulation. You may notice discoloration, bulging, or soft spots around damaged areas.

Moes Concrete handles both new stucco installation and repairs for residential and light commercial properties in Ontario and surrounding areas. New applications are designed to match existing textures and colors, so repairs blend in without standing out. The process involves cleaning damaged sections, applying a bonding agent, layering scratch coat and brown coat, and finishing with a color-matched topcoat. For larger projects, new stucco is applied over properly prepared lath and weather-resistant barriers to create a continuous exterior shell.

How Stucco Repairs and Installations Work

When repairing stucco in Ontario, the crew begins by removing loose or damaged material around the affected area, then cleans the substrate to ensure proper adhesion. A bonding agent is applied before the first coat goes on, and each layer is allowed to cure before the next is added. The final coat is textured and tinted to match the surrounding surface, so the repair integrates without visible seams.

After the work is complete, you will see a smooth, uniform finish that protects the wall from moisture and weather. Cracks are gone, and the surface no longer feels soft or spongy when pressed. Properly applied stucco forms a hard, breathable shell that regulates moisture movement and resists fading in direct sunlight. New installations follow the same layering process, with metal or fiber lath fastened to the sheathing and a water-resistive barrier installed beneath.

Moes Concrete uses materials and techniques familiar to Southern California building standards, which prioritize moisture control and thermal performance. Stucco work often coordinates with window and door trim, and repairs may involve flashing or sealant upgrades around these openings. The service does not include structural framing repairs, but the crew will identify any underlying issues that need attention before finishing the exterior.

Common concerns about stucco work

Homeowners in Ontario often want to know how long repairs take to cure, whether new stucco will match their existing finish, and what causes stucco to crack in the first place. These details help you understand what is happening behind the surface and what results to expect.

What causes stucco to crack on exterior walls?
Cracks form when the building settles, when stucco is applied too thickly without proper curing time, or when moisture gets trapped behind the surface and causes expansion. Poor flashing around windows and doors also contributes to localized cracking.
How long does stucco take to cure after installation or repair?
Each layer needs 24 to 48 hours to cure before the next coat is applied. Full curing can take up to 28 days, but you can expect the surface to be hard and weather-resistant within a week under normal conditions.
Why is it important to match the texture and color during repairs?
Matching texture and color ensures the repair blends with the rest of the wall and does not create visible patches. Moes Concrete uses samples and custom mixes to replicate the existing finish as closely as possible.
What happens if water has already damaged the wall behind the stucco?
The crew will assess the underlying structure and recommend repairs to the sheathing or framing before applying new stucco. Stucco itself is durable, but it only performs well when applied over sound, dry substrate.
How does stucco hold up in Ontario's climate?
Stucco performs well in dry, hot climates and resists fading and cracking when properly installed. It breathes enough to release trapped moisture but forms a tight seal against wind and rain when combined with proper flashing and sealants.

Stucco work restores curb appeal and strengthens your home's exterior against the elements. If you need stucco repairs or are planning a new installation in Ontario, call Moes Concrete to schedule a consultation and review your options.
