Cap off redundant drain pipe

[AdamD]

Had issues with rodents recently, cctv drain survey suggests a hole in the pipe, was quite clear from the camera. The area where it is is a redundant drain pipe and we need to excavate and cap it off. What sort of cost should I have in mind for my quotes? Ball park obviously.

How hard depends on the type of ground to dig, depth, and type of pipe that needs capping (clay or pvc)?

 

But even of your visitor is getting into your drains, how is he getting into the house from there?

How deep do you have to dig? Assuming you maybe need to excavate the connection, take out a 'T' joint and replace a straight section the digging is probably the worst bit. Assuming the drain is circa 100mm you can get sleeves with jubilee clips to span the gap (or 2 smaller sleeves and an infill bit of pipe if it's a wider gap). Cross-posted with @ProDave.

Concrete and likely earth below that. Not sure how far, maybe 0.5-1m.

It’s a clay pipe. 
 

Not sure but could be from the sewer, through the broken pipe and burrowing in. Hard to tell.

Not sure at this stage. No idea how to find out how deep it is. It’s like 18m from the manhole where we started with the cctv camera and uphill.

The problem is we don’t know they are getting in that way, but we also don’t know they’re not. No other clear entry points and where the evidence was is commensurate with this bit of broken pipe. Crap like this is a shot in the dark in a way, feels like dead money but ultimately it’s a 90 year old house so dodgy clay pipe work feels sensible so it’s one of those do we risk them coming back by saving this cost or bite the bullet and say well that’s another avenue closed

 

any ball park cost estimates?

Seriously, a 90 year old house will be full of cracks and gaps that a mouse can get through.  They can get through the holes in an air brick.  You will NOT stop mice getting into that house.  Get some poison or your preferred type of trap and treat it as something you have to do living there.

 

My present house built to be air tight, is the first house I have lived in where so far the only mouse we have had in the building got in through an open window.  Otherwise they don't get in here.
