Water surfacing from the damp earth, humidity coming into from crawlspace vents, and moisture seeping via porous concrete creates a perfect surroundings for condensation, mildew and mildew.

No worries, But yes you must have some type of ventilation, both trickle vents within the home windows, acoustic trickle vents in the walls or a warmth recovery system.



  • We learn online about moisture in insulation and marvel if that can be the problem.
  • This home was in-built 1953 and the previous house owners by no means had one and we haven’t both.
  • We’ve checked with our neighbors who have the same raised basis and pink oak hardwood floors and no one else has a vapor barrier both and have had no problems.

There are approximately 6.6 million dwellings in the UK built before 1919, predominantly constructed with suspended timber ground floors whose thermal performance has not been extensively investigated. The results are presented from anin-situheat-move measuring campaign carried out at 27 locations on a suspended timber ground flooring, and the estimated whole-floorU-worth in contrast with modelled results.
