Home DIY

we're getting some cold air entering into kitchen from behind the
cabinets mounted on the external wall. assume this is because there's
a hole somewhere (for services?) that the builder just thought would
be out of sight, out of mind when the cabs are placed.

think I've discovered potential source for this in (unheated) basement - where the new mass abuts the old, holes have been left (e.g. to feed wiring from front of house to rear.) I assume this is just letting cold air blow right into some space behind the cabinets... not sure what the configuration is beyond these holes between the two masses and whether there are any gaps in insulation. though presume there's some gap somewhere. don't see anything on the external wall - so this seems like the most obvious ingress point. still waiting to hear from the architect. could this be fixed by stuffing these holes with rock wool? sorry about pish photies

this is v. annoying and presumably a function of the completion work being done around march 2020 just as everyone went into lockdown. this meant e.g. the architect couldn't come visit and so we had to compile our own snagging list for the defects liability period. building standards have had to do all their inspections virtually too so they haven't picked this up. hopefully the contract term (5 year contractor liability for 'faulty' work) will cover us

edit: just heard back from architect. builder's on the case whew
