About our new build mastic in Whitehawk
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on kitchens, bathrooms & en suites and show homes, and common reasons people get in touch are joints pulling apart as timber shrinks and cracked caulk along new skirting.
In smaller places like Whitehawk, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Joints and finishes in Whitehawk homes
Whitehawk is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Whitehawk, as everywhere, new build mastic is only as good as the preparation behind it.
Whitehawk is about 1 mile south-east of Brighton, in Brighton and Hove. From the centre of Whitehawk to the outskirts, new build mastic is available for homes and businesses alike, from flats and houses to offices and hotels. Across Brighton and Hove, we cover 30 places, Whitehawk among them.

Local landmarks in Whitehawk

What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a smaller place like Whitehawk, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

FAQs for Whitehawk
Is Whitehawk in your area for new build mastic?
Yes, Whitehawk is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Whitehawk?
Yes, Whitehawk is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Are you insured?
Yes. We are fully insured.
How we quote for new build mastic
There’s no set price list, because jobs vary so much. What we look at:
- Which sealant suits the joint
- When we can work, for business premises
- Whether the work is at height
- The size of the job
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Where the property is
- Pictures of the joints, sent by email
- Whether it has been sealed before
- Any access issues, like height or stairs
Need a quote? Please phone 0345 464 0079 or send us an email and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Record problems with dated photos
- Look at the sealant regularly in the first couple of years
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with straight away
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What we are called out for in Whitehawk
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 before the sealant goes on.
Most people get in touch when they notice one of these:
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
- Leaking shower tray seals in a new home
If you’ve bought a new home near Brighton station, the sealant around baths, showers and frames is worth checking in the first year or two.

Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of plots in most cases.

- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
