Commercial Hardwood Floor Refinishing in Duluth, MN
Offices, restaurants, retail floors, churches, function halls and the historic buildings downtown. Commercial hardwood fails differently from residential: the finish goes first, in defined traffic paths, long before the wood itself is in any trouble.
Scheduling Around Your Business
Most commercial work here runs evenings, overnight or across a weekend. Offices go Friday evening to Monday morning. Restaurants get done between close and open. Where a space cannot close at all, we section it and work one zone at a time with containment between zones, which takes longer overall but keeps you trading.
Finish Specification
Commercial-grade water-based polyurethane, three to four coats rather than the two a home receives. It cures harder and faster than oil-based, and the low odour matters when people are back in the room the next morning. In a Duluth winter, with the building sealed and the heat running, that odour difference is not a minor consideration.
Historic and Institutional Floors
Duluth's downtown and its older churches and halls hold some of the best wood in the region: heart pine and old-growth oak, laid when the ore money was building the city, and in many cases never properly serviced since. These floors are frequently thin from earlier sandings.
They get measured before anything is switched on. Where thickness is marginal the right answer is a screen and recoat rather than a sanding, precisely because there is not much wood left to spend.
Maintenance Beats Refinishing
The cheapest commercial floor is the one that gets recoated on schedule. A recoat every two to four years in a busy space costs a fraction of a full sanding and removes no wood. We will quote the refinish you asked about and then tell you what the maintenance cycle should look like, because that is where the money is actually saved.
What It Costs
Commercial refinishing runs $4 to $8 per square foot depending on condition, coat count and access. After-hours and phased work carries a premium for the scheduling rather than the labor. Maintenance recoats run $1.50 to $3. Everything is quoted in writing after a site visit, with the reopening time stated up front.
Can you work outside our trading hours?
Yes, and for most commercial work that is the default. Offices and retail typically go Friday evening to Monday morning. Restaurants are done between close and open. We plan around your hours rather than ours.
How soon can we reopen?
With commercial-grade water-based finish you are usually back on the floor in socks within hours and in normal use the next day. Oil-based needs 24 hours between coats and is rarely the right choice for a space that has to reopen quickly.
Do you work on historic buildings?
Yes. Duluth's downtown and its churches hold heart pine and old-growth oak laid a century ago, often thin from earlier sandings. These get assessed for remaining thickness before anything is switched on, and sometimes the right answer is a recoat rather than a sanding.
What finish stands up to real commercial traffic?
Commercial-grade water-based polyurethane at three or four coats rather than the two a house gets. It cures harder and faster. For heavy traffic we set out a recoat schedule up front, because recoating on time costs far less than sanding again.
Can you phase it so we stay open?
Usually. We section the floor and work one zone at a time with containment between them. It takes longer overall but you keep trading.
