PVC gutters – joint failure

Cause

Solvent joint failure

Repair

  • when working at height, always let someone know. Ensure the access ladder is safe and is securely set up on stable ground. It is always safer to work from a platform such as scaffolding rather than leaning out from the top of a ladder

  • remove the failed section(s) of gutter, if necessary by cutting with a fine tooth saw. Where joints and other elements are unbroken, clean thoroughly, removing any old adhesive. It may be possible to refix these in place with new solvent cement. With proprietary PVC systems, replacement connectors, corners and lengths of gutter are available and are generally welded together with solvent cement

  • replace any damaged brackets. Brackets securing the guttering may be internal (hidden) or external, depending on the guttering profile. Fix with stainless steel fixings at least 20 mm long. Brackets should be generally no greater than 500 mm apart, or 300 mm in areas of high wind or in areas where snowfall is possible, but check what the manufacturer recommends

Cause

Initial installation did not allow for thermal expansion and contraction 

Repair

  • as for the first repair, but also install proprietary expansion joints or expansion outlets in the guttering. Just slide the spouting into these – to allow for movement, do not fix these with solvent cement
