Redhill New Build Mastic
Professional new build mastic in and around Redhill, with every bit of old sealant taken out first.
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- New-build shower sealant that has already split
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
About our new build mastic in Redhill
We work in new homes and on new-build sites across Redhill. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. Typical jobs include untidy sealant flagged on a snagging list and second-fix sealing on new plots, across skirting & floors, plot handovers and show homes.
In a town like Redhill, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Why it’s worth doing now in Redhill
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Black mould and gaps in sealant do not fix themselves, and in a busy home in Redhill they get worse with every use. Now is the easy time to put it right.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

What we’re called out for in Redhill
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
Any of these means the joints need attention:
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Internal frame sealant that has split
If you’ve bought a new home near Redhill station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Redhill
I let a flat near Redhill station. Can you help?

Is new build mastic in Redhill guaranteed?
All our work, in Redhill and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule ready for handover. Get in touch with the number of plots and the scope and we will quote.

Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.

New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
