Remedial sealant for homes and businesses in Summerstown
The wrong product in the wrong joint will not last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We are often asked to deal with gaps opening along the back of the worktop and sealant that came away because the surface wasn’t prepared, across failed movement joints, mouldy bath & shower sealant and expansion joints.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Summerstown are no different.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Bathrooms and kitchens in Summerstown
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as St Mary's Church, walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Earlsfield station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How the job changes by surface
Windows & doors
Some leaks around windows come from the wall or the window itself. If the frame joint isn’t the cause, we’ll say so.
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Why act early in Summerstown
Another bead over the top won’t fix a failed joint. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Cracks in the fitting rather than the joint
- Plumbing leaks behind walls or under trays
- Movement from fittings that are not supported
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

- Expansion joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant

How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. In Summerstown, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Keep children and pets away from the work area
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can

Advice
Signs you need remedial sealant in Summerstown
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Look out for these signs:
- Dark patches showing through the sealant
- Beads that never stuck properly
- Thick, messy sealant smeared over tiles
- Kitchen joints letting water behind the worktop
Managing a site like Burntwood School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
What your quote should include
- When the joint can take water or movement
- How the surfaces are prepared before sealing
- Is the old sealant removed completely?
- Who does the work, and how experienced they are

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Your questions about remedial sealant in Summerstown
Do you work for landlords with property near Earlsfield station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
I live in a flat in Summerstown. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What happens if the problem is the tray or the plumbing?
Then we explain what we have found. A plumber or fitter may be needed.
My shower still leaks after a reseal. Can you sort it?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
