What is the cost per square foot for polished concrete flooring as a finished surface in a NB home?

Polished concrete flooring in New Brunswick typically costs $8-$15 per square foot for a basic polished finish, with decorative options ranging $12-$25 per square foot fully installed. This makes it a mid-range flooring option that's particularly well-suited to NB's challenging moisture conditions.

The cost breakdown includes surface preparation ($2-$5/sq ft), grinding and polishing ($4-$8/sq ft), and sealing ($1-$2/sq ft). Decorative elements like acid staining, integral colour, or exposed aggregate patterns add $3-$8/sq ft to the base price. For a typical 800 square foot basement or main floor area, expect total costs between $6,400-$12,000 for basic polished concrete, or $9,600-$20,000 with decorative finishes.

Polished concrete offers significant advantages in New Brunswick's Maritime climate. Unlike hardwood or laminate that expand and contract with humidity changes, concrete remains dimensionally stable through NB's extreme seasonal swings from 20% winter humidity to 65%+ summer levels. The sealed surface is completely waterproof, making it ideal for basement installations where moisture migration through concrete slabs is a constant concern. In coastal communities like Saint John, Shediac, or Bathurst, polished concrete won't be affected by salt air or persistent dampness that can damage other flooring materials.

The installation process requires existing concrete in good condition — cracked, severely uneven, or oil-stained slabs need repair work that adds $3-$6/sq ft to the project cost. New concrete pours specifically for polished flooring run $6-$10/sq ft before polishing begins. The grinding and polishing process takes 3-5 days and creates significant dust, so plan for plastic sheeting and air filtration during installation.

Polished concrete works exceptionally well with radiant floor heating, which is increasingly popular in NB homes during our long heating season. The thermal mass stores and releases heat efficiently, creating comfortable temperatures underfoot while the polished surface reflects light to brighten basement spaces. However, without radiant heat, concrete feels cold during NB winters — consider area rugs in living spaces.

Hire a professional for polished concrete installation. The specialized grinding equipment, diamond polishing pads, and chemical densifiers require experience to achieve consistent results. Poor technique creates visible swirl marks, uneven sheen levels, and premature wear that cannot be easily corrected. Most NB flooring contractors subcontract polished concrete to specialists with the proper equipment and training.
