FAQs for South Tottenham
I let a flat near Seven Sisters station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Could a tired shower seal in my South Tottenham flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What information do you need?
A short description and the location. If we need more, we will ask.
Do you guarantee remedial jobs?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
How long does remedial resealing take?
That depends on how many layers there are and how many joints. You’ll have a timescale before any work begins.
Remedial sealant in South Tottenham
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and remedial work carries our one-year guarantee. If you have products that weren’t meant for the joint and wide, uneven beads that look worse than the old ones, we can help.
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.
Each job carries a 12-month guarantee, large or small.

What affects the quote in South Tottenham
The price is agreed before any work begins. It takes into account:
- Whether there’s mould to deal with
- Whether the work is at height
- The number of rooms or windows
- The old material and how stubborn it is
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before we start.
What to tell us for a quote
To make quoting easier, let us know:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Any previous sealing or DIY work
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
Why act early in South Tottenham
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. 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 is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What remedial sealant looks like in South Tottenham
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 has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Earlsmead Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Seven Sisters station?

What the job involves on each surface
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Don’t point over movement joints
- Never seal over old silicone
- Check trays and worktops don’t move
- Keep an eye on the ceiling below the bathroom
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
