New build mastic in Withdean
Across Withdean, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you’re dealing with kitchen sealant that has pulled off the wall and untidy sealant flagged on a snagging list, we can put it right, whatever the surface.
If you’ve bought a new home in or near Withdean, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
All of our work is guaranteed for twelve months.

What we’re called out for in Withdean
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.
These are the problems we are asked about most:
- Gaps between new skirting and floors
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
For new homes near Preston Park station, it’s worth checking the sealant early, while snags are still fresh.

What new build mastic looks like in Withdean
Withdean is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Withdean, as everywhere, new build mastic is only as good as the preparation behind it.

Different surfaces, different methods
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. In a smaller place like Withdean, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in

Looking after it afterwards
Looking after new joints is easy:
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
- Keep photos and emails about snagging items
- Raise failed sealant with the developer while you’re covered
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.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
What affects the quote in Withdean
You’ll get a clear quote before we start. It’s based on:
- Which sealant suits the joint
- Access and height
- How much old sealant there is and how hard it is to remove
- The size of the job
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
What to tell us for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Where the property is
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or drop us an email.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
When it isn’t the sealant
A few problems are outside what sealant work can do:
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
- Disputes or warranty claims with your builder
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Common questions in Withdean
Do you work for landlords with property near Preston Park station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Withdean within the area you cover?
Yes. Withdean is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
How do I get a quote for new build mastic in Withdean?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items and we’ll give you a quote. We’ll tell you if anything on it is not a sealant job.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, large or small.
