What is DOFF Steam Cleaning and Why Choose It?

DOFF steam cleaning is a superheated, low-pressure steam system (up to 150°C at the nozzle) designed specifically for sensitive heritage applications. Unlike traditional pressure washing or chemical cleaners, DOFF uses minimal water volume and no abrasives, making it ideal for removing biological growth, grime, paint, graffiti, and pollutants from historic masonry. This method is accredited by organizations like English Heritage and aligns with Parks Canada Standards and Guidelines for the Conservation of Historic Places in Canada.
In BC’s coastal climate—where moss, lichen, algae, and salt deposits are common on Victoria’s historic structures—DOFF provides a safe, effective solution. It kills spores and biofilms at the root without saturating or eroding soft brick, sandstone, limestone, or terracotta. Benefits include:
• Gentle on Delicate Surfaces: Low pressure (under 5 bar) prevents etching, cracking, or mortar erosion—perfect for protected heritage sites. • Eco-Friendly and Chemical-Free: Uses only superheated water, reducing environmental impact and avoiding residue buildup.

• Versatile Applications: Effective on exteriors, interiors, roofs, and monuments—suitable for residential heritage homes in Oak Bay or commercial facades in Gastown.

• Long-Term Protection: Removes contaminants that cause decay, extending the lifespan of your building and potentially qualifying for heritage grants like those from the Vancouver Heritage Foundation or Heritage BC.
With over 75 years of combined experience, our team has applied DOFF cleaning to high-profile projects like Government House, Craigdarroch Castle, and the City Halls in both Victoria and Duncan—delivering results that honor BC’s architectural heritage.

Our DOFF Steam Cleaning Process

We follow a meticulous, heritage-compliant process to ensure optimal results with minimal risk:
1. Initial Site Assessment: We conduct a thorough inspection of your property in Victoria or the surrounding areas, identifying soiling types (e.g., biological growth, carbon staining) and substrate fragility. This includes test patches to confirm DOFF’s suitability.
2. Preparation and Setup: Protect surrounding areas, ensure proper water supply, and calibrate the DOFF Integra for low-pressure operation. We use extension hoses and poles for hard-to-reach spots, minimizing scaffolding needs.
3. Steam Cleaning Execution: Apply superheated steam in controlled passes, removing contaminants layer by layer. Our trained operators monitor temperature and pressure to avoid over-saturation or thermal shock.
4. Post-Cleaning Inspection and Care: Rinse residues, assess results, and provide maintenance recommendations—such as periodic inspections to prevent re-growth. We also offer documentation for heritage grant applications or insurance purposes.
This process typically takes 1–5 days depending on project size, with minimal disruption to your site.
