It all depends on the square footage, how much repair is needed. If the entire wooden floor needs to be repaired, then the repair may take longer. I would advise you to contact this company for Wood Flooring Repair in London https://woodenflooringexperts.co.uk/wood-floor-repair-london/ They do it quickly and with high quality. But if there are a lot of repairs, they won't do such repairs cheaply. Wooden floors are hard to repair, especially if the wood is soft.
