How we handle remedial sealant in Somers Town
In Somers Town, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. We are often asked to deal with repeat leaks from the same joint and decorators’ caulk around a bath or shower, on expansion joints, failed movement joints and leaking tray & enclosure joints.
Hard London water leaves limescale on sealant, grout and taps alike. In Somers Town, remedial sealant is as much about a room looking cared for as about keeping water out.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

For landlords and businesses
Housing providers, facilities teams and property managers book us too in Somers Town and across Greater London. Several sites can go on one quote, and we are fully insured for the work.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Leave it or put it right?
Ripping out a bathroom isn’t usually needed. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you’ll hear it from us. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What you get with us
- Any old sealant cut out fully, not covered over
- Trusted Arbo and Everbuild sealants
- White, clear, grey or another colour, product permitting
- You choose the colour before work begins

Bathrooms and kitchens in Somers Town
Somers Town has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
If you let a flat or house near London Euston station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. In the older streets around St Mary's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Somers Town is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

The process
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. In Somers Town, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints

What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- Access and height
- The old material and how stubborn it is
- Working hours on commercial sites
- The number and length of the joints
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we’ll talk you through it.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The type of property
- Roughly how big the job is
- Photos by email, if that’s easy
- Any previous sealing or DIY work
There’s no standard price list. Instead, we give you a clear price for your job. To get started, call 0345 464 0079 or drop us an email.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild products only
- Keep movement joints clear of mortar and paint
- Always have old sealant cut out, not covered
- Run the fan after every shower
Do not let anyone seal over it later. New silicone does not bond to old.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
When it isn’t the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Movement from fittings that are not supported
- Water damage behind tiles that needs a tiler
- A tray or bath that’s cracked
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
