Remedial Sealant in Harlow
Problem with your failed sealant joints in Harlow? We remove the old material, prepare the joints and seal them properly.
- Sealant peeling off a dusty or damp surface
- Products that weren’t meant for the joint
- Wide, uneven beads that look worse than the old ones
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Remedial sealant for homes and businesses in Harlow
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. If you have over-sealed joints coming away and floor or wall movement joints that have failed, we can put it right.
In a town like Harlow, older streets sit alongside newer estates, and bathrooms range from decades-old suites to brand-new ones. Either way, the sealant and grout are normally the first things to fail.
Our work is backed for twelve months, in Harlow and everywhere else we cover.
How it works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours, depending on how many layers have to come out in most cases. Parking in a town like Harlow is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any tricky access
- Mention if the joints have been sealed before

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
What sealant work can’t fix
We will not take on work that will not last, so here’s what sealant cannot put right:
- Tiles that have come away from the wall
- Sealant in an older building that needs testing for asbestos first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Botched or over-sealed joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
What we are called out for in Harlow
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Look out for any of the following:
- Black mould underneath the bead
- Decorators’ caulk around a bath or shower
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
If you look after a building such as Cooks Spinney Primary Academy and Nursery, we reseal washrooms and kitchens in schools and businesses as well as homes.

What affects the cost of remedial sealant
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- Whether the work is at height
- Any working-time requirements on site
- Any mould that needs treating
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- The problem you’ve noticed
- A few photos by email, if you can
- How we’d reach the joints
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job and send photos if you have them.
Questions from Harlow
Can you do remedial sealant in Harlow?
Yes. We work across London and the South East, and Harlow is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Should the sealant in an older Harlow home be renewed?
Normally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.
What happens if the problem is the tray or the plumbing?
That’s why we look for the cause first. If the fault is elsewhere, you’ll know before any work is done.
Bathrooms and kitchens in Harlow
Harlow is one of the post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. New sealant will not stick to old, so the old layers have to come out first. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Harlow Town station? Then a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as St Andrew's Methodist Church, older homes can move a little, which is hard on rigid grout and tired sealant.

Why act early in Harlow
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. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Harlow they spread with every shower and every downpour. Now is the easy time to put it right.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
