Why FS Group
Our engineers set out from two bases, one in Walthamstow and one in Waltham Abbey. From there they reach every London area below, plus the towns of Essex, Kent and Hertfordshire. Each area page lists the streets and postcodes we visit, with reviews from people nearby.
Weekdays from 8am to 6pm, a standard unblock is charged per half hour. Ring first and you learn the rate before an engineer leaves.
See all our ratesHad a booking issue initially, but when called in the morning, engineer promptly came, and sorted the issue (blocked drain) very efficiently and thoroughly. He also walked us through the issue and pricing and made sure we understood the choices before proceeding. Would not hesitate to use again. 5*
Excellent service from FS Drainage I had a blocked outside pipe & Jordan had it cleared in a short time no fuss or drama just got on with the job he explained why I had the problem & what to watch out for to prevent from happening again very happy with the service. Carol - Harlow
We were extremely impressed with the service provided by FS Drainage Services. They came out the same day at a reasonable, set price and the plumber was very quick, friendly and efficient. I would highly recommend them.
Speedy and effective service plus good advice from a friendly engineer for the agreed fee. What more can you ask?
He arrived on time, cleared the drains and was very friendly and informative. He then cleaned up after himself and disinfected the floors with Zoflora. The charge was very fair and in accordance with the quote. I will definitely use them again and highly recommend them.
A small but complex blockage was expertly cleared by Josh. Much appreciated and will most definitely use again. Thank you Josh.
