Frequently Asked Questions

For External Plumbing Specialists In Exeter

Here’s everything homeowners usually ask us about our external plumbing services in Exeter when replacing or upgrading their water supply pipe. We’ve broken it down so you know exactly what to expect.

Before the Job Starts

❓ How much does it cost to replace a water supply pipe?

It depends on the length and access.
We provide clear quotes upfront, and we keep things competitive. Trenchless installs are often cheaper overall because they reduce reinstatement costs.

❓ Are you insured and certified?

👉 100%.
We’re fully insured, Street Works certified, and follow all industry regulations, so you’re in safe hands.

❓ How long does a water main install take?

👉 Most jobs are done in a day — including reinstatement. Bigger or more complex installs may take a little longer, but we’ll keep you informed every step of the way.

❓ Do I need permission to replace my water supply pipe?

Not usually.
In most cases, we handle all necessary notifications and coordination with the water supplier. If anything specific is needed, we’ll guide you through it.

❓ Can you replace the water pipe from the street to my house?

Yes — that’s exactly what we do. We can replace or upgrade the pipe from the boundary stop tap right into your home.

❓ How do I know if my pipe is made of lead?

If your home was built before 1970, there’s a good chance. Lead pipes are dull grey and soft. If you’re unsure, we offer quick inspections to check.

❓ Will you need to dig up my garden or drive?

Not if we can help it.
We use trenchless moling wherever possible, it lets us install new pipes without disturbing the surface. If we do need to dig, we keep it tidy and fully reinstate everything.

While We’re on the Job

❓ Can I stay in the house while the work is being done?

👉 Absolutely.
We work mostly outside, and we keep mess and disruption to a minimum.

❓ Will my water be turned off during the job?

Yes, but only for a short time.
We’ll always give you notice and aim to keep any disruption to an absolute minimum. We reconnect everything as quickly as possible.

After the Job’s Done

❓ What if I spot an issue later?

👉 We stand by our work. If anything doesn’t seem right, just give us a call and we’ll put it right.

❓ Do you tidy up after?

👉 Always. Whether we’ve dug or used moling, we reinstate everything, turf, gravel, concrete, or tarmac.

❓ Will I need to contact the water board again?

👉 Nope — we’ll usually handle all closing notifications and paperwork so you don’t have to.
