FAQs for Bullsmoor
Could a tired shower seal in my Bullsmoor flat affect the neighbours below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Can you help a landlord with a rental near Turkey Street station?
Yes, we work for landlords and letting agents. You can phone 07833 053749 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
How long does remedial resealing take?
Allow a few hours, depending on how many layers have to come out. You will know the timing when we quote.
What if resealing will not fix my leak?
You’ll hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we won’t pretend it will.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
How we handle remedial sealant in Bullsmoor
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out before the joint can be done properly. If you’re dealing with floor or wall movement joints that have failed and sealant peeling off a dusty or damp surface, we can help, on expansion joints, leaking tray & enclosure joints and mouldy bath & shower sealant alike. Some people call us the mastic man, others the silicone man or the sealant specialist, but the work in Bullsmoor is the same: old material out, joints prepared and the right product used.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Bullsmoor are no different.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Advice
Honest limits
To be straight with you, some problems need a different trade:
- Plumbing leaks behind walls or under trays

- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you are not sure, just ring 07833 053749 or email us and we will give you a straight answer.

How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- How many areas need sealing
- Which sealant suits the joint
- The number and length of the joints
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
Asking for a quote
When you call or email, these details help:
- What’s wrong with the joints now
- A few pictures by email, if you can
- Where the job is, and your postcode
- The type of property
If you’re in Bullsmoor and need remedial sealant, ring 07833 053749 or email us. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Leave it or put it right?
Mould under a bead cannot be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Bullsmoor, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before any work starts.

What else we do in Bullsmoor
Common problems we fix in Bullsmoor
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Most people get in touch when they notice something like this:
- Products that weren’t meant for the joint
- Repeat leaks from the same joint
- Gaps opening along the back of the worktop
- A second bead peeling off the first
If you look after a building such as Honilands Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Questions to ask before you book
- How hidden problems are handled
- Who does the work, and how experienced they are
- Whether they’re fully insured
- Which colour the sealant will be
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What remedial sealant looks like in Bullsmoor
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
For an older house near a landmark such as St George's Church, walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Turkey Street station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not wait for a small gap to become a leak
- Get the cause of a repeat leak found before resealing
- Look for stains below bathrooms now and then
- Keep bleach and abrasives off the bead
Keep the room ventilated: run the fan during and after showers, or open a window.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
