JAC LTD - Building Surveyors
All properties require maintenance on a regular basis or they eventually become dilapidated and day to day or planned/cyclical maintenance is the only way to keep your property or portfolio in a fit state of health.
Before you make up your mind to purchase a property, it should be surveyed by a professional surveyor, to make sure it is both structurally & cosmetically sound, however, there are some very basic checks that you can carry out first before spending money on any type of survey.
"A pair of binoculars, a good eye and some common sense will be all that is initially required".
Maintenance as a topic can be extremely extensive, however, partly due to the amount of questions we receive daily on dampness, this topic seems as good as any to detail further.
We have detailed throughout this guide, the three most common causes of dampness and hope this information will be on some assistance to you.
Rainwater Ingress
  1. Poorly capped chimney.
  2. Faulty rainwater protection where chimney stack passes through roof.
  3. Displaced roof tiles.
  4. Faulty coping stone, without damp–proof course (dpc).
  5. Defective parapet & valley gutter lining.
  6. Lack of cavity tray over window head.
  7. Defective rainwater pipe & hopper.
  8. Cracked felt on flat roof & incorrect fall to same.
  9. Missing lead soaker adjacent to flat roof.
  10. Rain splashback over dpc.
  11. Defective render.
  12. Mortar droppings on tiles between two leaves of a cavity wall, transmitting penetrating rain to inner wall.
  13. Defective window cill admits water.
  14. Poorly painted window frame.
  15. No threshold to prevent driving rain.
Rising Damp
16. Earth bridging dpc.
17. Earth retaining wall not tanked.
      No vertical damp proof membrane (dpm) & no  air brick ventilation to cellar.
18. Missing dpc under joists resting on sleeper wall.
19. Missing dpc under floor & door frame.
20. Persistent dampness to a solid floor may be caused by faulty/missing dpc/dpm.
21. Blocked ventilation gaps to roof.
22. No air brick to gable wall.
23. Interstitial condensation in flat roof, due to no vapour barrier present.
24. No flu vent in blocked up chimney breast.
25. Cold spot condensation on solid concrete lintel.
26. Condensation behind pictures & in cupboards, due to lack of ventilation.
27. Condensation at the bottom of an external wall.
