How do I remove old glued-down commercial carpet from a concrete floor in my Miramichi office building?

Removing glued-down commercial carpet from concrete requires mechanical scraping, adhesive removal, and proper disposal — this is heavy physical work that typically takes 2-3 days for professional crews. The age of your Miramichi building determines whether asbestos testing is required before starting.

Commercial carpet removal is fundamentally different from residential carpet that's simply stretched and tacked down. Commercial installations use pressure-sensitive adhesive that bonds the carpet backing directly to the concrete slab, creating a permanent attachment that requires aggressive mechanical removal. The carpet itself will come up in sections, but the real work is removing the adhesive residue that remains bonded to the concrete.

Start with asbestos testing if your building was constructed or renovated before 1986. Commercial carpet adhesives from this era commonly contain asbestos fibres, and disturbing these materials without proper containment releases hazardous particles. Testing costs $25-50 per sample and takes 2-3 days for results. If asbestos is present, you'll need a licensed abatement contractor — never attempt DIY removal of asbestos-containing materials.

For non-asbestos installations, rent a walk-behind floor scraper (available at equipment rental shops in Miramichi for $150-200/day). These machines use oscillating blades to cut through the carpet backing and scrape adhesive from the concrete surface. You'll also need a heavy-duty shop vacuum, plastic sheeting to contain debris, and proper ventilation — this process creates significant dust and fumes. Plan for 150-300 square feet per day depending on the adhesive type and your experience level.

Adhesive removal requires chemical strippers or continued mechanical scraping. Water-based adhesives (more common in newer installations) respond to warm water and scraping. Solvent-based adhesives need chemical strippers — ensure adequate ventilation and follow all safety protocols. The concrete surface must be completely clean before installing new flooring, as any remaining adhesive will prevent proper bonding of new materials.

This is demanding physical work that most building owners hire out. Commercial flooring contractors have specialized equipment (ride-on scrapers, industrial adhesive removers, dust collection systems) that completes the job in 1-2 days versus 4-5 days for DIY efforts. For office buildings in Miramichi, expect removal costs of $2-4 per square foot depending on the adhesive type and disposal requirements.

Consider hiring a professional if your building is over 1,000 square feet, if you suspect asbestos, or if you need the space operational quickly. Find commercial flooring contractors through the New Brunswick Construction Network who have experience with adhesive removal and proper disposal of commercial carpet waste.
