Remedial sealant for homes and businesses in Shoreham
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have photos when you phone 0345 464 0079 or drop us an email, and say how long ago it was last done. If you have leaks that keep coming back after resealing and floor or wall movement joints that have failed, we can put it right, on failed movement joints, shrunken worktop sealant and expansion joints alike.
Somewhere as small as Shoreham, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
There’s a 12-month guarantee on every job, large or small.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Plumbing leaks behind walls or under trays
- A cracked shower tray or bath (that needs repair or replacing)
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Expansion joints
- Botched or over-sealed joints

Remedial sealant in Shoreham: local notes
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.
Schools such as Shoreham Village School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Shoreham (Kent) station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

How the visit works
You do not need to clear the whole room or building before we come, 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 for a typical job. Somewhere as small as Shoreham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Advice
Signs you need remedial sealant in Shoreham
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Keep an eye out for any of the following:
- Sealant that came away because the surface wasn’t prepared
- Repeat leaks from the same joint
- Products that weren’t meant for the joint
- A second bead peeling off the first
For an older house near a landmark such as Church of St Peter and St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.
Before you book anyone
- What product goes in the joint
- Are they insured?
- How long to leave it before use
- How the surfaces are prepared before sealing
Questions from Shoreham
Do you cover Shoreham for remedial sealant?
Yes, Shoreham is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Do you cover smaller places like Shoreham?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Shoreham, along with the rest of our area.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Looking after it afterwards
Aftercare is simple:
- Keep an eye on the ceiling below the bathroom
- Never fill a movement joint with mortar or grout
- Have loose fittings fixed before resealing
- Keep bleach and abrasives off the bead
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.

Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and tell you about any damage we find.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. We will reseal and tell you if extraction looks to be the issue.
