How much does it cost to apply a whitewash finish to interior exposed brick in an Ottawa loft?

Whitewashing interior exposed brick in an Ottawa loft typically costs $3 to $8 per square foot, meaning a standard accent wall (100-150 square feet) runs $300 to $1,200, while a full loft with multiple exposed brick walls can reach $2,000 to $4,000. The wide price range depends on the brick's condition, desired opacity level, and whether you're hiring a professional or tackling it as a DIY project.

Ottawa's loft conversions — particularly in Centretown, the ByWard Market, and Hintonburg — often feature beautiful century-old brick that's perfect for whitewashing. The technique involves applying a thinned paint mixture that allows the brick texture and some original colour to show through, creating that sought-after industrial-chic look. However, Ottawa's dry winter air (often below 20% humidity) actually works in your favour for this project, as the low moisture helps the whitewash cure evenly without blotching.

For a DIY approach, you'll need about $30 to $50 in materials per 100 square feet: white latex paint ($40-60 per gallon covers roughly 400 square feet when thinned), mixing medium or water for thinning, brushes, rags, and drop cloths. The key is working in small sections while the mixture stays workable — apply with a brush, then immediately wipe back with rags to achieve the desired transparency. Professional application adds $2 to $5 per square foot in labour but ensures consistent coverage and proper surface preparation.

Critical considerations include testing your mixture on an inconspicuous area first, as Ottawa's older brick can be quite porous and absorb whitewash differently than expected. Some heritage loft buildings may have lime mortar that reacts differently to modern paints, potentially requiring specialized products. Also, whitewashing is difficult to reverse completely, so commit to the look before starting.
