How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
New build mastic in Brighton and Hove
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for beads laid onto grit and dust from the build and cracked caulk along new skirting, on bathrooms & en suites, skirting & floors and windows & doors.
Homes around Brighton and Hove move a little with the seasons, and skirting and floor joints show it first. Those joints need a flexible sealant, as rigid filler soon cracks out.
A one-year guarantee comes as standard, so you are covered after we have gone.

Questions from Brighton and Hove
Can you help a landlord with a rental near Aldrington station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Is new build mastic in Brighton and Hove guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Black mould and gaps in sealant do not fix themselves, and in a busy home in Brighton and Hove they get worse with every use. Now is the easy time to put it right.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours for most snagging lists, longer for a run of plots. In Brighton and Hove, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Signs you need new build mastic in Brighton and Hove
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry.
If you can see any of these, it’s time to have the joints looked at:
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
- Sealant that never bonded to the surface
If you’ve bought a new home near Aldrington station, the sealant around baths, showers and frames is worth checking in the first year or two.
