New build mastic in Brighton Hill
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have messy sealant that spoils new finishes and cracks appearing as a new home settles, we can put it right, whatever the surface.
In smaller places like Brighton Hill, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
Your job is guaranteed for a year, as with all our work.

Your questions about new build mastic in Brighton Hill
Do you work for landlords with property near Basingstoke station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Is Brighton Hill in your area for new build mastic?
Yes. We work across London and the South East, and Brighton Hill is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope and we will quote.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
Should I go to my builder first?
Start with the builder if you’re in the snagging or warranty period. If it isn’t resolved, we will cut it out and reseal it.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.

What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- How easy the joints are to reach
- How many areas need sealing
- When we can work, for business premises
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- Where the property is
- Any previous sealing or DIY work
- Any access issues, like height or stairs
If you’re in Brighton Hill and need new build mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before work begins.
How to look after the new joints
To keep the joints looking good and working properly:
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
- Keep pictures and emails about snagging items
- Don’t wait for the house to settle if water is getting through
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Do you need new build mastic in Brighton Hill?
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 first.
The most common problems we see are:
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
- Plot mastic for developers ahead of handover
For new homes near Basingstoke station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
