Reaching/filling holes behind kitchen units

byron55

Has anyone had any experience with finding and filling holes behind kitchen units without ripping whole kitchen out?

We bought a duplex (top two floors) fourteen years ago and have had intermittent issues with mice over the years. We know they get in from kitchen on top floor - units spread over two walls - likely from holes under gas boiler in corner. We once sawed hole in bottom shelf of unit under this corner and filled a huge hole in corner of floor with cement. This had an impact for a while. We also pulled out fridge freezer and filled holes around pipes, which also had effect only for while (these fillings have not been touched by mice, so these were not the problem). This last winter we had a bad mice problem again.

The kitchen is not in bad condition - if we didn't have this issue we would be likely only replacing the doors, but I think this will be a waste of money in long run.

I can't see any other solution to end the issue once and for all but to rip out units and block up every single gap the builders left.

I was just wondering if maybe anyone on here has had similar problems with their kitchen? Any advice would be greatly appreciated.

you will need visual on the holes.
What I done for the gaps at bottom of dabbed pb behind the kick board is use length of qualpex with expanded foam gun.
if you get visual, albeit it at a distance, then compressed chicken wire in the hole first and then the foam

Thanks Calahonda,
Aye, I think the corner cupboard will have to come out at least - can see rest of walls with torch, but can't get good enough view of that corner. Thanks for the tip on the chicken wire.

can the back of the cupboard come out some are just 4mm , else cut the back out, leaving an inch or so all round and then you can cover it with a slightly bigger piece

So at the weekend I pulled out the washing machine fully and got access to the frame under the counter top. I can see two large holes I missed those years ago when I cut through lower shelve in corner. I can't reach them properly without taking out the panels but I'm sure these have to be the problem, so definitely not considering ripping out kitchen anymore. When I get a day free, I'm going to dismantle this corner as much as I can/need until I reach them well enough to do good job on them. Shocking the way things were left behind the units but I guess builders aren't thinking of mice. Thanks for the advice.
