MEASURING
Measure length of fascia,
allowing enough for mitres
and any joints that may
be required. Generally,
external corners will
require at least twice the width of the gutter to be sacrificed making
the mitre, but internal corners require no extra material. Joins should
overlap approx 100mm. If installing pre-made stop ends no extra
length is required, but “return” stop ends require the width of the
gutter to be added for each stop end.
DETERMINE GUTTER SUPPORT
There are 4 basic methods of supporting a gutter.
A: External brackets.
B: Internal straps and P clips.
C: Internal straps and scotia.
D: Suspension clips and internal straps.
DETERMINE GUTTER FALLS
1: Using a string line, nail one end to
the fascia, running string line from
corner to corner, making sure the
string line is taut.
2: The fall of the gutter should be
calculated (correct fall is 1:500).
Check the fall with a spirit level.
The fall must run towards the
gutter outlet.
EXTERNAL BRACKETS
Nail External brackets at 1.2 metre centres,
following string line. Once all brackets
have been installed, place gutters into
external brackets. Bend tag over bead to
hold in place
P - CLIPS
Install P-clips if required using the same
method as external brackets. Once
P-clips have been installed, sit gutters
onto P-clip lip then bend small tag of
P-clip over back of gutter to hold the
gutter into position.
INTERNAL STRAPS
Install internal straps at 1.2 metre
centres to hold face of gutter into
position. Install pre-made mitres into
corners. Internal straps can also be used
in conjunction with gutter suspended on
timber scotia nailed to a timber fascia.
SUSPENSION CLIPS
This can be used on steel & timber
Fascia with Internal Straps. No string line
is required. For timber fascia nail your
timber suspension clip into place by
placing a clout into the allocated hole in
the top of the clip and driving the clout
into the top of the timber fascia, holding
the clip into position. Clips are to be
placed at maximum of 1.2m centres.
Steel fascia suspension clips are rolled
over the top of steel fascia and placed
into position at 1.2 m centres. (See
section on steel fascia).

1: Ensure all gutter outlets and stop ends are fitted at the correct
locations prior to installation of the gutter.
2: Place gutter on P-clips or scotia already
installed and hold into place by driving
a galvanised nail into the fascia just
above the back of the gutter. Bend the
nail down to hold the gutter but allow
expansion and contraction.
3: To install the next length of gutter,
determine the fall of the gutter. Joins
should always be overlapped to allow
water to flow “over” the joint instead of
“into” the joint. Open the bead of the
“outside” gutter with a pair of pliers, and
close up the bead of the “inside” gutter.
4: Slide the upstream gutter (inside) into
the downstream gutter (outside) allowing
a 100mm lap. Rivet and silicone the two
gutters together, ensuring that all metal
filings (swarf) are first cleaned from the
gutter. Silicone should be smoothed to
ensure that the passage
of water is not impeded.

PRE-ASSEMBLE MITRES, STOP ENDS AND OUTLETS.
Determine method of supporting and strengthening gutter on the
fascia. Gutter support can include external brackets, or internal
straps used in conjunction with either P-clips, timber scotia or
suspension clips.
1: Cut required length with hacksaw and tinsnips.
2: Fit stop ends where required.
3: Cut holes (outlets) for gutters with a hacking knife, and rivet outlet
into position.
4: Cut mitres where needed. Pre-made mitres are available. See the
section on making mitres if you wish to make your own.
5: Remove all swarf and debris from inside of gutters. If gutters
are pre-coloured steel remove plastic from outside of gutters prior
to installation.
6: Seal internally all stop ends, gutter outlets and mitres with
silicone sealant.
7: Make downpipe offsets. Pre-made downpipe offsets are available,
however see section on making offsets if you wish to make your own.
