After seeing recommendations on here, we've just used Back To Wood (Steve and Nichola) to restore and stain the floorboards in our lounge and on our landings. Highly recommend them - the floors are transformed and crucially for us - there was almost no dust! They even worked over the weekend so that the landings could be done whilst we and the kids were out of the house. You might have to wait a bit for them as they get booked up, but if there's no time pressure I'd say they're worth hanging on for. 07949 411650
