Highlights

I've known Crystal DMS for some years and have always found their work to be excellent. We had a seriously blocked drain reported by a tenant at 5 pm last Saturday; I called Crystal, they responded immediately and the drain was cleared 2 hours later. Superb service as always.

NigelTrustATrader5.0 rating

I would like to thank Jordan and Sam for an efficient job. They explained the issue in detail and resolved it promptly. Thank you!

HannahTrustATrader5.0 rating

We have had ongoing problems with a partially blocked toilet for several years. Three different plumbers and Dynorod have all been out without solving the issue. I chatted with Paul and it was clear that he understood the problem and was confident he could solve it. Jordan and Sam came out the next day. They were able to clear the drain within 2 hours. They explained to us exactly what they were doing as they went along and showed the clear drains when they had finished. I wish we had called Crystal DMS first!

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.

Check the WaterSafe register
Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
