Sewardstonebury Remedial Sealant
Failed sealant joints in Sewardstonebury need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Wide, uneven beads that look worse than the old ones
- Mould trapped under a layer of silicone
- Sealant peeling off a dusty or damp surface
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
How we handle remedial sealant in Sewardstonebury
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. Typical jobs include a second bead peeling off the first and thick, messy sealant smeared over tiles, across failed movement joints, expansion joints and mouldy bath & shower sealant.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Sewardstonebury, that’s a good reason to put tired sealant and grout right early.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What else we do in Sewardstonebury
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why act early in Sewardstonebury
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Sewardstonebury, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Sewardstonebury: your questions answered
Is parking a problem for a job in Sewardstonebury?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Chingford station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Are you fully insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
How long does the work take?
That depends on how many layers there are and how many joints. You will have a timescale before any work begins.
Different surfaces, different methods
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. We strip it back so we can see the joint.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours for a typical bath or shower, longer where several layers have been applied, and we tell you how long to leave it before we go. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Keeping the joints in good condition
So the new joints stay in good condition:
- Always have old sealant cut out, not covered
- Do not point over movement joints
- Clean sealant with mild products only
- Run the fan after every shower
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
