When you are going to lay your new floor, you need to begin by looking at the base. What does the existing floor look like? Does the base consist of a concrete slab, wood floor, mat, parquet or maybe masonite? If you have an old floor that is whole and undamaged – then you can lay your new floor on top. If it is an old wall-to-wall carpet, we recommend that you remove it. If you have a concrete slab, you should make sure that it is smooth and even.
If you want to be sure of getting a floor that lasts a long time, it's important that it's laid on a good base. If you let an old, squeaky floor stay there under your new parquet, the problem will still be there. You will basically get a new floor that squeaks.
Uneven surfaces in the base can be a strain on the new floor, causing it to sag and shortening its life.
Neither creaking or unevenness mean that you are forced to tear out your old floor. If you fix the creaking sections and fasten floor boards and level out an uneven base, it is perfectly OK to let it stay there. But this does not apply to carpets. A carpet can attract moisture and create an environment where mould thrives.
Also remember that it's important to choose the right underlay. In some cases, a moisture barrier is needed between the old and the new floor. If you are unsure of what to do with your old floor, don't hesitate to ask your Pergo dealer.
Although it might not look so bulky when it's laid out flat, quite a bit of work might be needed to remove an old floor. Think about both the space and the weight. A regular trailer is probably enough. Wood floor, vinyl floor and laminate should be turned in to the recycling centre and sorted as combustible material.
