We have a Victorian mid-terrace, with a condensation problem in our subfloor area. A builder has recommended getting a french drain installed around the external walls to try and dry the area better.
When posting on here should I post in builders or drainage specialists?
The builder we spoke to said that the job would be around 2500 (+VAT). This would include excavating concrete, digging the trench, leaving for a few months to dry out and then returning to fill. Also the waste would need to be taken away.
Is this a fair estimate as it seems like a lot to me?
It's probably around 30 ft split between the front and back.
