How we handle new build mastic in Boyton Cross
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on windows & doors, plot handovers and bathrooms & en suites, and the jobs we see most are sealant work across a run of new homes and skirting joints opening in the first winter.
For a small place like Boyton Cross, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Don’t seal over failed sealant yourself
- Record problems with dated photos
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Boyton Cross: your questions answered
Is Boyton Cross within the area you cover?
Yes. Boyton Cross 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.
Do you cover Boyton Cross for new build mastic?
Yes. Our work covers London and the South East, and Boyton Cross is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can landlords and businesses book you?
Yes, often. Several properties can be quoted together.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
What should I tell you?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
What happens on the day
We keep the work tidy and contained to the area we’re working on. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. For a village or hamlet like Boyton Cross, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.

Advice
Why act early in Boyton Cross
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few photos and we’ll tell you. Older cottages and farmhouses around Boyton Cross can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

What we’re called out for in Boyton Cross
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
These are the problems we’re asked about most:
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
If you’ve bought a new home near Chelmsford station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- The length of the guarantee
- How the surfaces are prepared before sealing
- What happens if the job turns out different
- How much experience the applicator has

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
