What we do
The whole envelope.
Water rarely respects trade boundaries. Northspan looks at the exterior as one connected system, finding the real source of a problem before recommending the right repair.
01Building Envelope Restoration
Coordinated repairs that restore performance across connected exterior systems.
We address the full exterior assembly—not just the visible symptom—coordinating the systems and transitions required for a lasting repair.
- Condition assessments
- Failure investigation
- Air and water barriers
- Flashing and transitions
- Sealants and control joints
- Localized reconstruction
- Drainage improvements
- Close-out documentation
02Water-Infiltration Investigation
Practical investigation to identify how and where water is entering the building.
Water can travel far from its entry point. We review adjacent systems and vulnerable transitions before developing a focused repair scope.
- Leak-source investigation
- Roof and wall review
- Window and door transitions
- Flashing assessment
- Masonry moisture concerns
- Below-grade leakage
- Drainage and grading review
- Repair recommendations

Northspan develops and delivers coordinated renewal programs that improve appearance, weather resistance and long-term performance while respecting operations and budgets.

- Multi-system coordination
- Phased construction
- Resident communication

Repairs that restore the safety, appearance and weather resistance of exterior assemblies.

- Brick and stone replacement
- Mortar repointing
- Concrete repairs
- Lintel and sill repairs
- Chimneys and parapets
- Control-joint sealants
