Images of how end section of gutter joins with down pipe connection.

The gutter ends short and the two ends are held with mastic.

Is this how it should be done ?

Is it acceptable ?

There is a little upstand mid way between the two ends which leads me to imagine the two ends should terminate there.

Should there be rubber sealing strips in evidence ?

My experience of gutters is extremely limited but any I've done had an engineered overlap at the connections and a rubber seal inserted there.

No.

There should be a moulded mark to indicate where the end of each section
of gutter goes - to allow for expansion/contraction.

Yes.

its a major bodge!

Not really - normally the joining pieces have an internal rubber seal
that is designed to allow the gutter to slide in the fitting as it
changes length with temperature. Sealing it solid with silicone etc is
not usually a good move since you are in effect gluing the bits together.

Is it acceptable ?

In a normal joint, no. At the end of a run and connected to a downpipe -
that depends on how much free movement the downpipe allows. If the top
is free to move a bit from side to side as the gutter changes length it
might hang together.

There is a little upstand mid way between the two ends which leads me
to imagine the two ends should terminate there.

When "hot" yes - they may be left a bit short in cold weather.

Should there be rubber sealing strips in evidence ?

They are normally part of the fitting - you won't see them unless you
dismantle the joint to look.

Many thanks for the replies. It gave me the courage to tackle the
supplier. He responded to say that the rubber gaskete are in place
and the mastic is a belt and braces effort. Claims they used a low
modulus sealant. Would this still allow sufficient expansion and
contraction ?

Good story - must remember that one :-)

It's a complete bodge. Silicon doesn't stick to plastic gutter in the long term. The only way to join gutter or down pipes is with solvent glue, which melts the two surfaces together. Even this is not the practical for gutter joints; rubber seals and unions are for this. To hold down pipes and off set joints use solvent glue
