The floorboards were nailed right on top of the joists and had concrete subfloor below. We not only had to replace any damaged or missing boards, we also had to check the condition of the joists to make sure they are not rotten. We were also tasked with insulation fitting as well as subfloor preparation. The combination of so many assignments at once made our job harder and more time-consuming. However, as fully trained professionals we knew more than enough to provide excellent results. And we did, as usual.
Floor sanding and refinishing is more about changing the appearance of the wood and preventing problems in the future. It is important to do it whenever the need arises but when the damage is already there, the situation becomes a lot more complicated.
If the floor had been properly maintained and taken care of, the more extensive and obviously expensive repairs would have never been needed. After extensive examination, we discovered that despite their non-uniform appearance, the joists were not rotten or damaged. We did not have to replace them.
The next step was preparing the subfloor and seeing to the floorboards. We already knew which needed replacing and salvaged those we thought could be reused. You can clearly see the distinction between old and new pieces on the pictures below. After securing the boards and ensuring the floor is stable, we could proceed with the easy part – the sanding.
