How we handle remedial sealant in Forestdale
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. If you are dealing with wide, uneven beads that look worse than the old ones and gaps opening along the back of the worktop, we can put it right.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Forestdale more than a cosmetic job.
Big or small, it’s backed by our one-year guarantee.

For landlords and businesses
Landlords and letting agents in Forestdale can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What affects the cost of remedial sealant
We do not publish a price list. The quote depends on:
- When we can work, for business premises
- The number and length of the joints
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
What we need to know
Photos help, but a description is a good start. Please mention:
- Where the property is
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work.
Can I do it myself?
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Forestdale. It helps if you can point us to a visitor permit or a bay close to the door.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
How to get a quote

Forestdale homes and their sealant
London has hard water, so limescale builds up on sealant, grout and fittings. 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.
As a London address, Forestdale can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Courtwood Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St Francis, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Forestdale: your questions answered
Could a tired shower seal in my Forestdale flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. A proper reseal before the leak starts is the easy fix.
Can you help a landlord with a rental near Sanderstead station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
Is remedial work guaranteed?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Can I choose the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before any work starts.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Always have old sealant cut out, not covered
- Keep movement joints clear of mortar and paint
- Find out why the sealant failed first
- Look for stains below bathrooms now and then
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
What happens if it’s left?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.
