Full on site surveys for diy installer’s or tradesmen

A full on site survey is an essential part of installing a wood floor covering of any kind in your home or commercial setting. Think about what could go wrong if adequate checks are overlooked. To take a chance on a small room is one thing, but to take a chance when you’ve just invested a good deal of money in your new wood floor or been commissioned to carry out work for a client, could be seen as reckless and unnecessary.

What can go wrong? 

You install a nice new wood floor covering on top of a not always so obvious wet sub-floor.

 Warped moisture damaged floor from rising moisture damageDo not let this happen because you took a chance!!


Moisture damage! If your floor soaks up moisture from a wet sub-floor, it can swell and expand excessively. There are a number of well documented ensuing results such as Buckling, Cupping, Damp smells, Mould growth, De-bonding and unsightly Plank separation!

You install a nice new wood floor covering on top of an uneven sub-floor. Bounce! If your sub-floor is uneven you will be left with a Bouncy or Spongy feeling to your new floor with potential further issues of Joint abrasion leading to Plank separation and the common problem of Excessive creaking!

The 'sleeve method' relative humidity test being carried out..

 You can avoid all of this by getting a professional on-site survey! Get advice before you install! Get peace of mind! 

What you’ll receive by calling us to carry out a site survey? 

  • Room relative humidity test : The ideal RH of a room is between 45 – 55%. Anything less or anything more, you risk the wood flooring contracting or expanding excessively. We will assess this and give you prior knowledge before you fit the flooring in sub standard conditions, risking wasting your money, replacing the floor or at the least having to live with a failed floor. If you’re a conscientious tradesmen that’s taken on the task of fitting an expensive wood floor and it’s out of your field, give us a call! There’s no need to buy £500 worth of equipment. Get reassurance at a fraction of the cost as well as any technical advice suited to the particular installation.
  • British standards compliant for testing relative humidity be expelled from a concrete sub-floor.Surface relative humidity test : Surface RH should be below 75% for solid sub-floors. This isn’t an obvious issue and requires specialist equipment to assess. Using the British standards humidity box method for concrete sub-floors, this non-invasive test is carried out over a 72 hour period. It is the safest way to know the sub-floor is suitable. If the reading comes back above 75% we can advise you on the best way to proceed. This service falls under our ‘comprehensive survey’ charge.
  • Surface relative humidity test : Using the none British standards but highly regarded for accuracy ‘sleeve method’ for concrete sub-floors. This is an invasive test requiring the sub-floor to be drilled to allow placement of the sleeves. The sleeves are then left in for a 72 hour period. This method is ideal should the site be busy as there is less chance of disturbing the sleeves over the time period. It cannot be used to test sub-floors with underfloor heating! We can carry these tests out in one visit (included with our ‘basic survey charge’) should you wish, but the results may not be as accurate as the recommended test parameters. This service falls under our ‘comprehensive survey‘ charge.
  • A full ventilation check for suspended timber sub-floors : If there’s a lack of adequate ventilation, this can have a huge effect on the climate conditions both under the floor and above it. Poor ventilation can also leave joists rotting and a constant damp smell in your property. We can inspect the sub-floor ventilation and give guidance on how best to resolve the issue.
  • Direct moisture testDirect surface moisture content requires assessing with specialist equipment : For both wood sub-floors and solid. We can test the direct moisture content of your sub-floor and give advice should the readings come back high or low.
  • Sub-floor level check : This is best done with a seasoned and experienced eye and a straight edge. It’s always good to get a second opinion on how best to level an uneven floor from the correct preparation to using the best and correct materials. This is a key part of any floor covering and more so with a wood floor due to the associated installation problems ensuing from an uneven sub-floor.
  • Advice on how to deal with moisture issues to prevent future problems : From natural drying techniques to sub-floor moisture suppression. This advice can take a lot off your mind and give you the reassurance that all will be well after you’ve installed the floor.
  • Correct wood floor acclimatisation and storage advice : This is often overlooked but is an extremely important process when fitting a wood floor. We will advise you of the best place and condition to store your floor prior to the installation. We always take manufacturers guidelines into consideration and work their requirements to suit your individual situation.
  • Wonder what are friend thinks?Installation advice : We can answer any questions you may have and give handy hints and tips on the best way to install your floor for both ease to yourself and a great finish. Covering aspects such as correct starting points (this can be a head scratcher when taking on a job you’re not used to), safe working practises (in any property or building there can be dangers lurking – get advice if you’re unsure), final finish (gain insider knowledge on how to finish your floor best with the tools you have) and maintenance for a long lasting wood floor that will look great for years.
