I think I might get a drain camera. That worked out at £525/hr + VAT.
Good news; no roots in the drains.
Bad news; There's a "belly" in the pipe, so the, er, solids, settle half-away along the run, so it'll have to be dug up and relaid. And no, I'm not doing it myself.
What are the drains made of? Is it pitch fibre? thats about all I can think of that might move over time (with the soil) to give you that Belly effect. UPVC and glazed ceramic shouldn't do this.
They're PVC. And no, they shouldn't move, but they have.
How long is the "belly". PVC will move several inches over a 3 m length. Glazed ceramic came in 3' (4'?) lengths with a fair bit of play in each socket.
Under a driveway that has had heavy vehicles passing or parked near the route fo the drain. How far down are they?
Of course they might not have been properly beded in when installed and they have just settled.
That seems an unbelievably high figure to me. I think I paid no more than a couple of hundred for a survey plus jetting, must have taken more than an hour. Or was it (say) £150 including a fair callout charge for something that they managed to do in a quarter of an hour? The full kit in a typical van (camera plus pressure washer plus long flexible hose) is not cheap.
anything will sag over time if there is subsidence under it
That seems steep for a camera survey the guy who jetted our blocked drain o ffered to do a survey for £150 if the problem came back.

The latter, of course.
It didn't take an hour ...
Assuming they were laid right in the first place...
About 3m
No. They run along the rear wall of the house, adjacent to the garden. I'm hoping they're in the French drains, which will make them easy to dig up.
Start off 40cm down and finish about 70cm down, over some 20m.
Judging by the standard of "workmanship" in this house, that's my suspicion. Combine that with the fact we've just refitted both bathrooms with so-called "water saving" cisterns, and there isn't enough "whoosh" to carry the poo through.
Big assumption, here.
Much travelling time?
OK, but in that case "rate per hour" is not really the thing to quote.
That said, I do agree that the falling price of drain inspection kit means that it could well be a reasonable investment, especially if you know you won't have to look too far from an access point.
Dyno-Rod did used to rather milk their monopoly power at one time, there is much more competition now.
No sounds a bit yuck to me. Brian
Sadly some of the upvc kind can be cracked according to thames water. Its stress normally.
Brian
Ah, so Thames might be correct. Could be roots under the belled area in the split maybe? Brian
About 10 minutes if they charge at the same rate as the chap I had do a TV survey.
That's why they are supposed to be sitting on a bed of pea shingle
100mm deep, then covered and surrounded with another 100mm deep layer of pea shingle, and then if less than a certain distance from the surface, at least 4 inches of concrete to prevent damage from enthuastic gardening or diy.The Thames water area is predominently clay which does tend to swell and shrink.
