So first some background on Damp proofing
It is reckoned that we spend an average of 90% of our life indoors. Moisture is an important factor in the quality of any indoor space, for example there is evidence of a link between damp housing and respiratory problems in children.

So conditions need to be right
Incorrect moisture levels can reduce comfort, and increase stress as well as influencing the occupant's health. Johnson Ellis Ltd., Damproofing in Hemel Hempstead can assist with solutions.

Damp Proofing In St Albans

Damp Proofing in St Albans

There are 3 main types of dampness

  • rising damp ( from outdoors via air and ground )
  • penetrating damp ( from contact with wet materials )
  • condensation ( from indoor activities and conditions )

Damp in Hemel Hempstead and Damp proofing in St.Albans

All of these are likely to create damage to a building, resulting, at best, in defects in the decorations and at worst wet and dry rot thus weakening structural timbers.

Before initiating any remedial work it is essential to assess

  1. is dampness present ?
  2. is the building suitable for a particular treatment ?
  3. is the building being modified and will that affect any treatment.?

A Johnson Ellis Ltd survey will take into account all of the factors and we will only suggest remedial works if you need them.
