New build mastic in Goddards Green, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. We work on windows & doors, kitchens and skirting & floors, and the jobs we see most are kitchen sealant that has pulled off the wall and sealant that never bonded to the surface.
Somewhere as small as Goddards Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Common questions in Goddards Green
Do you cover smaller places like Goddards Green?
Yes, we do. 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.
Is Goddards Green in your area for new build mastic?
Yes. Our work covers London and the South East, and Goddards Green is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
How it works
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours in a single home. In a small place like Goddards Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Keep pets and children clear of the area while we work

Related advice
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Older cottages and farmhouses around Goddards Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Signs you need new build mastic in Goddards Green
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
Any of these means the joints need attention:
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Cracked sealant around new window and door frames
- Joints pulling apart as timber shrinks
For new homes near Burgess Hill station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- How the joint is cleaned and prepared
- What happens if the job turns out different
- Whether they seal over old material or remove it
- Who turns up on the day
Surface by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.

DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
