In our experience neither of these ‘solutions’ work as the circular brush still allows debris to pass through into the gutter and attracts moss which grows on the brush itself. Leaves stick to the brush allowing rainwater off the roof to run over the top and down the walls. They become cumbersome and messy and have to be removed as the gutters will still need clearing!
The plastic grid guard that attaches to the top of the gutter has the same problem of still allowing debris to pass into the gutter and then build up on top of the grid. It is then necessary to remove the grid before the gutter can be cleared.
In most cases where these products were in place the customer requested not to have them re-installed.

GutterGleam offer a comprehensive gutter clearing service – as well as clearing the gutters of debris – we check and clear all drainpipe bends for blockages, check for damage to fascias and carry out repairs to leaking joints. We use ladders as well as industrial vacuum cleaners for difficult hard to reach areas such as over conservatories etc.
We recommend the installation of small plastic cowls that sit in the top of the drainpipe to prevent future blockages and that gutters are cleared at least once a year.
We can, on request, survey the outside of your property for any other potential problems before they become costly.
