Check Your Subfloor Before Fitting Wood Flooring

[Era line] Vetus-19When you’re planning to purchase a new wood floor, one essential thing in your checklist should be your subfloor. Sadly, something which’s often disregarded, your subfloor plays a far more important role in the look and the longevity of your hardwood floor than you might give it credit for. Thus, before you go ahead and put a recently purchased hardwood flooring, take the opportunity to test out what lies beneath. Here are a few things you need to think about…

Learn exactly what your subfloor is Made from

The very first thing you you need to establish is that the substance of your subfloor. The most common subfloors are wooden boards and concrete. If you lift an older carpeting or an old wood floor you are going to get a very clear impression of the state of your subfloor and one of the principal things to identify would be what it is made from.

In case your subfloor is constructed from planks, you are going to come face to face with the issue of whether you need to place a layer of ply over the planks or when the planks are adequately secure to stand until the guide installation of your new flooring. To be able to earn any type of assessment of this ground, you have to check out the planks carefully to determine if they’re secure, well repaired and at reasonable condition. Should they seem at all damaged or shaky, it is likely worth presenting a layer of ply prior to fitting your new flooring. But should you determine that the boards are in good order to maintain your new flooring, then you simply have to be certain they are well repaired and free of protruding nails and sharp items.

If you’re in any doubt, it is worth contemplating putting a layer of ply of your present planks. Ply is a superb surface to the new flooring and should not break your budget.

By carefully assessing and preparing your board subfloor properly, you may significantly enhance the general appearance and lifespan of your floor. NOTE: One more thing to keep in mind if you’re placing a new plank flooring right over an older one is that you need to put the new boards vertical (at a 90 degree angle) into the previous ones.


Concrete is one of the most frequent subfloors today and also the most essential issue to consult a concrete subfloor is your moisture level. Concrete subfloors will need to be in good shape and comparatively dry to help a brand new hardwood flooring successfully.

When it comes to measuring the moisture content, you can either get the pros in or employ or purchase a rust measuring machine. If you get the professionals in, you will not need to be worried about taking dimensions yourself. But should you opt to go it alone, you should take around 30 moisture readings and aim for a constant moderate across your readings of no more than 2-3%. Putting your new hardwood flooring over a damp subfloor will only stock up issues for the long run.

As soon as you’re satisfied that the moisture levels are within acceptable limits, you need to ensure the subfloor is free of old adhesive, lumps and bumps and is usually in good shape before going to lay your new flooring.

Might you want an underlay?

It’s a peculiar thing, but almost everyone accepts an underlay enhances a carpeted floor considerably, but many people don’t even think about underlay when fitting a brand new hardwood flooring. That is a shame, since regardless of what substance your sub floor is made of, a grade underlay will give you:

  • A great laying surface.
  • Increased energy efficiency.
  • Reduced danger of moisture.
  • Lessened noise pollution.
