Remedial Sealant in Manor House
Failed sealant joints in Manor House need attention? We cut out the old, prepare the joints and apply the right sealant.
- Dark patches showing through the sealant
- Beads that never stuck properly
- A second bead peeling off the first
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. In a London area like Manor House, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any tricky access
- On commercial sites, let us know about site rules

Remedial sealant in Manor House
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. Common call-outs are for a shower that leaks however often it’s resealed and mould trapped under a layer of silicone, on failed movement joints, expansion joints and shrunken worktop sealant.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
We stand behind the work with a one-year guarantee.

For landlords and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Movement from fittings that are not supported
- Older mastics that may need an asbestos check before removal
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

When to call us in Manor House
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
If you can see any of these, it’s time to have the joints looked at:
- Repeat leaks from the same joint
- Products that weren’t meant for the joint
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
Letting a property close to Harringay Green Lanes station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What affects the quote in Manor House
We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- Any working-time requirements on site
- The number and length of the joints
- The type of sealant required
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Asking for a quote
To help us quote quickly, please include:
- Where the property is
- How we’d reach the joints
- A few pictures by email, if you can
- Whether it has been sealed before
We don’t publish a price list, because every job is different. Instead, we send you a clear quote for your job. To get started, ring 0345 464 0079 or email us.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Don’t point over movement joints
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
- Check ceilings under showers for marks
Give the new sealant its full cure time: follow the cure time we give you.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
