Homebuyer Drain Surveys

Know what you're buying — before you sign the contract.

Drainage isn't covered by a standard homebuyer survey, and it's one of the most expensive things to put right if it fails after completion. A pre-purchase survey from DrainFixer gives you a WRc-standard CCTV video, a plain-English summary, indicative repair costs and negotiation leverage before exchange.

Common causes

  • Original Victorian clay pipework reaching end of life

Our process

How we handle homebuyer drain surveys

01
Book before survey stage
Ideally after a positive homebuyer survey but before exchange.
02
Full CCTV run
Every drainage run and chamber inspected.
03
Plain-English report
Written for buyers — no jargon, clear photos, defect grading.
04
Indicative repair costs
So you can negotiate on price or repairs before exchange.

Kit we bring

  • HD self-levelling cameras
  • Sonde locators
  • Plain-English reporting templates

While you wait — do

  • ✓ Book as soon as your homebuyer survey is booked
  • ✓ Get the vendor's consent for access in writing

Please don't

  • ✕ Don't wait until after completion — you lose all negotiating leverage

Common questions

Do I need the vendor's permission?▾
Yes — but 99% of vendors agree once your solicitor requests it. We can arrange the visit around their schedule.
How much can drainage repairs cost?▾
A small patch repair may be £400–£800. A full excavation and re-lay can exceed £5,000. A survey costs a fraction of that and can save thousands.
