Stucco & Exterior Finishing Services in Nepean

Homes from the 1960s-1970s building boom have parging that is over 50 years old and severely deteriorated. The original cement-sand mix has cracked extensively, with sections delaminating from the foundation wall entirely due to Leda clay settlement and decades of freeze-thaw.

On 1980s homes, stucco accent panels on upper storeys and gable ends have often failed at the transition to brick, allowing water infiltration. Proper flashing and counter-flashing at these material changes is critical during repair.

Nepean's homes with 1990s barrier EIFS face moisture problems compounded by the use of wood-based sheathing that is particularly vulnerable to rot. Re-cladding involves upgrading to drainable EIFS or acrylic stucco over a proper rain screen assembly.

Townhome complexes from the 1980s and 1990s with uniform stucco or EIFS exteriors require coordinated maintenance across multiple units. Aging sealants and failing finishes across entire complexes need systematic replacement programs.

Leda clay soil combined with Ottawa's deep 1.2 to 1.5-metre frost line creates significant heave forces on foundation walls. Spring snowmelt pooling against foundations where grading has settled over decades accelerates parging deterioration.
