What the job involves on each surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
New build mastic in Birchett's Green, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant normally lacks. If you have second-fix sealing on new plots and sealant that never bonded to the surface, we can put it right.
For a small place like Birchett's Green, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Big or small, it’s backed by our 12-month guarantee.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Joints and finishes in Birchett's Green homes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Stonegate station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Birchett's Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Advice
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few photos. Older cottages and farmhouses around Birchett's Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

How to look after the new joints
To keep the joints looking good and working properly:
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
What affects the cost of new build mastic
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- How much there is to do
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
For a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
Common questions in Birchett's Green

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you cover Birchett's Green for new build mastic?

No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Honest limits
In fairness, some problems need a different trade:
- A tray or bath that isn’t properly supported, until it’s fixed
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
