Can I fit gutters level?

At what centres do I fit fascia brackets?

Fascia bracket centres must not exceed 1m maximum centres. Fit an extra fascia bracket 150mm one side of any union, running outlet or stop end.  Angles must have a facia bracket fitted both sides within 150mm.

How do I control expansion and contraction?

Fit gutter to insertion mark on fitting and fix fitting to fascia board, following installation instructions. Deepflow, Deepflow150, Clip-master and Flowline can also be fitted using the notch-jointing technique with a notch adaptor.  Click here for step-by-step installation instructions.

What screws do I use to secure the fascia bracket to the fascia board, in order to fit gutter?

When fixing to cellular fascia boards the two outer-most fixing holes must be used and 1¼” x 10g (32 x 5mm) pan or round head non-ferrous screws should be used.  The use of countersunk screws is not recommended.

How should gutters be installed?

Gutters should be fitted as high as possible to the roof edge and fascia brackets should be set out with aid of a string line and level. Click here for full rainwater installation information.

How should the eaves edge be finished?

The roof tile over hang should be no greater than 50mm. Where over fascia vents are used, a spacer height adjuster (RGS1) should be fitted behind each fascia bracket.

Do you make special gutter angles?

Yes, special gutter angles can be made to order.  Please contact our Customer Services department on 01622 852585, stating the angle required.  Delivery time is usually 3-4 weeks.

What sizes are your rainwater downpipes?

Our downpipes are available in 68mm and 82mm circular, and 65mm square outside diameters

Can I fit your 68mm rainwater downpipes to 2½" cast iron?

Yes, 68mm pipe spigot usually fits into cast iron sockets, with the use of silicone sealant.

Do I need to fit a gully at the base of rainwater pipe?

Yes, if it's a combined sewer system

At what centres should I fix your rainwater downpipes?

At a maximum of 1.8m centres, using pipe clips on the downpipe barrel.  Remember to always support the socket on the end of the pipe using a socket pipe clip. 

What maintenance is required for gutters and rainwater downpipes?

PVCu is a good corrosion resistant material and only requires an occasional wash with soapy water.  Remove debris from the gutters and downpipes to ensure smooth flow and repair any defects immediately.
