Joint Sealing

The vast majority of industrial gutters are manufactured from galvanised steel which are bolted or riveted together usually at 3 metre intervals and then sealed with mastic.

Over the years the joint sealant deteriorates causing the joints to leak. These joints can easily and effectively be repaired by cleaning the joint and applying a primer and a new coat of sealant.

If the gutters have been vinyl lined the joints may be repaired by using new vinyl patches or a more economical option would be to apply torch-on felt patches to the defective areas.

Gutter Surface Treatments

Galvanised steel will over time start to corrode causing the gutters to rust, flake and eventually perforate. If left, this corrosion will degrade to such an extent that the gutters will need to be plated prior to any works, or in the worst case be replaced.

Most gutter surface treatments are determined by both the condition of the gutters and the longevity required. For example if you lease your building you may only require a treatment that will last for five years; however should you own the building you may require a guaranteed fifteen year treatment.

We have various alternative treatments to suit your requirements and only in the worst case situations would recommend a bespoke gutter lining system.
