Broxbourne Remedial Sealant
Failed sealant joints in Broxbourne need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Floor or wall movement joints that have failed
- Black mould underneath the bead
- Wide, uneven beads that look worse than the old ones
How we handle remedial sealant in Broxbourne
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We’re often asked to deal with over-sealed joints coming away and worktop sealant that has shrunk and split, across shrunken worktop sealant, failed movement joints and expansion joints.
In and around Broxbourne, older properties sit alongside newer ones. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Signs you need remedial sealant in Broxbourne
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.
The most common problems we see are:
- Thick, messy sealant smeared over tiles
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
- Sealant that came away because the surface wasn’t prepared
If you live in an older home near Church of St Augustine, older homes can move a little, which is hard on rigid grout and tired sealant.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t add new sealant on top of old
- Report a tray that rocks or a worktop that lifts
- Look for stains below bathrooms now and then
- Keep movement joints clear of mortar and paint
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or send us an email.
Do not keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

We quote each job individually. These are the things that affect it:
- How many rooms, windows or areas are involved
- How much there is to do
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work

We will always be straight with you, so here’s what new sealant will not do:
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on

- Botched or over-sealed joints
- Expansion joints

How it works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking around Broxbourne is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
How to prepare
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
