Stucco repair in Ottawa costs between $500 for minor patching to $15,000+ for full resurfacing. Ottawa's freeze-thaw cycles are particularly harsh on stucco, making cracks and deterioration common issues that need prompt attention to prevent water infiltration. Minor crack repair costs $500-$1,500 and involves filling hairline cracks with elastomeric caulk or stucco patching compound. Moderate repair (sections of damaged stucco) costs $1,500-$5,000. Major repair or resurfacing ($5,000-$15,000+)...
Cracking is the most common stucco problem in Ottawa. Hairline cracks (less than 1/16 inch) are usually cosmetic and caused by normal building movement. Wider cracks indicate structural movement or water damage and need immediate attention. Spider-web cracking (map cracking) often indicates the stucco was applied too thinly or dried too quickly during application. Water damage behind stucco is a serious concern. Signs include bulging or soft spots in the stucco surface, dark staining or discolo...
Elastomeric patching ($500-$1,500) uses flexible repair compounds that bridge hairline cracks and move with the building. This is the most cost-effective solution for minor cosmetic cracking. The repair is typically painted over with elastomeric paint for a uniform finish. Stucco section replacement ($1,500-$5,000) involves removing the damaged section, inspecting and repairing the substrate (building paper, lath, sheathing), and applying new three-coat stucco (scratch coat, brown coat, finish ...
If your stucco is severely deteriorated, consider whether repair or replacement with an alternative cladding makes more sense. Stucco repair costs $5,000-$15,000 for significant damage, while residing with vinyl ($8,000-$15,000), fibre cement ($12,000-$25,000), or engineered wood ($10,000-$20,000) provides a fresh start with potentially lower maintenance. Stucco advantages in Ottawa: excellent fire resistance, good sound insulation, customizable colours and textures, and a premium appearance. S...
Stucco work is a specialized trade. Look for contractors with specific stucco experience — general contractors and painters may not have the expertise for proper stucco repair. Ask to see completed stucco projects in Ottawa and check references. Get three quotes that include: scope of repair (patched area, section replacement, or full resurface), substrate inspection and repair, colour matching approach, warranty on workmanship (minimum 2 years for repairs, 5 years for resurfacing), and timelin...
Minor patching costs $500-$1,500, section replacement $1,500-$5,000, and full resurfacing $8,000-$15,000. Per square foot, expect $8-$30 depending on the repair method.
Ottawa's 50+ annual freeze-thaw cycles cause water to penetrate hairline cracks, freeze, expand, and widen them. Building settlement, thermal expansion, and impact damage also cause cracking.
Hairline cracks can be sealed with elastomeric caulk (DIY cost $20-$50). Larger cracks and structural repairs should be done by a professional to ensure proper technique and prevent water infiltration.
Properly maintained stucco lasts 40-60 years in Ottawa. Without maintenance, freeze-thaw damage can cause significant deterioration within 15-20 years.
EIFS (Exterior Insulation and Finish System) is a synthetic stucco applied over rigid foam insulation. It looks like traditional stucco but is lighter, more insulating, and requires specialized repair techniques.
