Drain Repairs questions.
How do I know if my drain needs repairing or just clearing?
If it blocks again soon after clearing, or you see wet patches, smells, or sinking ground, the pipe itself is likely damaged. A camera inspection confirms it before you spend on a repair.
Do you reinstate the ground after a repair?
Yes. Reinstating the site properly is part of every job, the ground put back so you would barely know we had been there.
Will you tell me the cost before you start?
Always. You get a clear price up front and a call before any extra work, so there are no surprises when the job is done.
