How we handle remedial sealant in Tower Hamlets
If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. We work on mouldy bath & shower sealant, failed movement joints and leaking tray & enclosure joints, and people most often call us about kitchen joints letting water behind the worktop and repeat leaks from the same joint.
Even in a smaller place like Tower Hamlets, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: all the old material out, the joint cleaned and dried, then new sealant or grout.
Your job is guaranteed for a year, as with all our work.

Tower Hamlets homes and their sealant
Tower Hamlets is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Tower Hamlets has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For site and facilities teams at buildings such as Priory Fields School, we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Dover Priory station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as Church of St Peter and St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.
Tower Hamlets is about 1 mile south of Dover, in Kent.

The process
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. The work generally takes a few hours for a typical bath or shower, longer where several layers have been applied. A visit to Tower Hamlets is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

What else we do in Tower Hamlets
How the job changes by surface
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. We strip it back so we can see the joint, then reseal neatly.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
How we quote for remedial sealant
The price is agreed before any work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- How much there is to do
- When we can work, for business premises
- The type of sealant required
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
Asking for a quote
When you contact us, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Whether it has been sealed before
For remedial sealant in Tower Hamlets, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Common questions in Tower Hamlets
Do you cover smaller places like Tower Hamlets?
Yes. Tower Hamlets is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Dover Priory station. Can you help?

Can you reseal a split movement joint?

Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
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.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Why act early in Tower Hamlets
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. In a smaller place like Tower Hamlets, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Looking after it afterwards
Aftercare is simple:
- Look for stains below bathrooms now and then
- Don’t wait for a small gap to become a leak
- Never fill a movement joint with mortar or grout
- Get the cause of a repeat leak found before resealing
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
