How to prepare for new flooring

Whether you go for vinyl, carpet or even ceramic tiles, changing your floor covering is a great way to give a room a new lease of life. But before you start work, make sure the surface underneath is sound and level. If it isn't, any defects are likely to show through. This will spoil the look of your new floor and eventually cause it to wear unevenly. Luckily, there are some effective ways to deal with problem floors which we will share with you.
