Wood Board & Batten Siding Restoration, Waterproofing & Water Damage Repair – Toronto
This Toronto exterior renovation project involved the complete restoration of deteriorated wood board and batten siding around an exterior door and window.
The existing wood siding had experienced significant deterioration and rot over time, particularly around the window and door openings. Once the damaged boards were removed, we discovered that moisture had also penetrated behind portions of the siding and affected the underlying wall assembly.
Instead of simply replacing the visible siding, the damaged areas were opened up so the source and extent of the deterioration could be properly addressed.
Removal & Water Damage Repair
The existing deteriorated vertical wood siding and battens were carefully removed around the affected sections of the exterior wall.
Once the wall was exposed, all accessible rotted and water-damaged wood was removed. Damaged sections of the underlying wall and wood components were repaired or replaced as required, providing a solid base before the exterior was closed again.
Special attention was given to the areas surrounding the window and exterior door, where previous water penetration had caused some of the most significant deterioration.
BlueSkin Waterproofing
Before installing the new exterior finish, the repaired areas were protected using BlueSkin self-adhered waterproofing membrane.
BlueSkin was installed at critical areas of the wall assembly and around vulnerable openings to provide an additional water-resistant barrier behind the exterior siding.
This was an important part of the restoration because the objective was not only to replace the damaged wood, but also to improve the wall's protection against future moisture penetration.
Window & Door Flashing
New metal head flashing / drip caps were installed above the exterior window and door.
These flashing details help direct rainwater outward and away from the top of the openings instead of allowing water to migrate behind the trim and siding.
Proper flashing was particularly important on this project because much of the original deterioration was concentrated around these vulnerable areas.
Silicone & Exterior Caulking
The waterproofing system was completed with exterior-grade silicone and professional exterior caulking.
Necessary joints, transitions, edges and penetration points were carefully sealed to help create a continuous weather-resistant exterior envelope.
Combined with the BlueSkin membrane and new metal flashing, the sealing work provides multiple layers of protection rather than relying on caulking alone to keep water out.
New Wood Board & Batten Siding
After completing the repairs and waterproofing, the exterior was rebuilt with new vertical wood board and batten siding.
The new boards were installed to maintain the architectural character and vertical appearance of the original façade while replacing the deteriorated sections with clean, solid material.
Window and door areas were carefully detailed so the new work integrated naturally with the surrounding exterior.
Custom Black Aluminum Door Trim
The exterior door surround was also upgraded with a custom black aluminum finish.
The black aluminum creates a clean transition between the wood siding and the existing door while providing a much sharper and more contemporary appearance.
The contrast between the natural wood board and batten siding and black aluminum detailing gives the completed entrance a distinctive modern look.
