Maida Vale

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.

I don’t often write reviews but I was seriously impressed by F and S Group. I texted them before 8:00 this morning, an immediate reply with same day service. The engineer, Will, was great- polite, professional and sorted my drainage issue which had caused a lot of stress and provided clear explanations so I knew exactly was happening. To top it off, it was a great price. Very impressed and will recommend this company to all of my contacts.

Josh was quick, professional and efficient! I contacted FS over a totally blocked up shower drain that I tried to clear using Mr. Muscle drain gel but it didn't work at all. Couldn't even penetrate into the drain because there was completely no more room in there. Josh came round within 2 hours of me calling and finished the job much quicker, within 15 minutes. I appreciate the dedication to quality service. I highly recommend! Cheers!

Fantastic service from start to finish. Went out of their way to accommodate me with a very blocked and problematic drain after a particularly heavy period of rainfall. Engineer was extremely professional and efficient, sorting out a drain blocked with years of building debris within 30mins. Amazing service, excellent value for money, would definitely recommend.

What we see most

The drain problems we fix most often in West London

Basements

Many houses in Kensington, Chelsea and Fulham have basements below the drain. Water there may need a pump to reach the sewer, so a blockage shows up fast.

Mansion blocks

Older blocks in Hammersmith and Maida Vale run long cast-iron stacks. We clear them from the top or the bottom, depending on where the blockage sits.

Shops and restaurants

Kitchens along Southall Broadway and King Street need grease kept out of the drain. We jet lines on a schedule so they keep flowing.

Shared stacks in conversions

In Notting Hill and Fulham, period houses converted to flats pass every floor’s waste down a single stack.

Leaves in front lightwells

Front lightwells in Kensington and Chelsea collect leaves in the gully, and rainwater pools at the basement door.

Roots in Ealing gardens

Interwar homes in Ealing and Acton have long garden runs where tree roots creep into the joints.
