- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
Aftercare tips
A little care helps the new joints last. We recommend:
- Open a window or run the fan after bathing
- Raise failed sealant with the developer while you are covered
- Look at the sealant regularly in the first couple of years
- Record problems with dated pictures
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
About our new build mastic in Southminster
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. We work on bathrooms & en suites, kitchens and skirting & floors, and common reasons people get in touch are leaking shower tray seals in a new home and sealant work across a run of new homes.
For a new home in or near Southminster, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Common problems we fix in Southminster
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
If you’ve bought a new home near Southminster station, the sealant around baths, showers and frames is worth checking in the first year or two.

What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to several days, depending on the number of plots, including the tidy-up. For a job in Southminster, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Advice
New homes and floors in Southminster
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

What affects the cost of new build mastic
There’s no set price list, because no two jobs are the same. What we look at:

Why it’s worth doing now in Southminster
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Southminster, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Colour agreed with you before work begins
- Experience in homes, commercial sites and hotels
- 20+ years of sealant experience
- An ARBOMaster approved applicator

How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
