How we handle new build mastic in Upton Grey
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 skirting & floors, plot handovers and windows & doors, and common reasons people get in touch are plot mastic for developers ahead of handover and leaking shower tray seals in a new home.
For a small place like Upton Grey, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

New build mastic in Upton Grey: local notes

Your questions about new build mastic in Upton Grey
Is Upton Grey in your area for new build mastic?
Yes. Our work covers London and the South East, and Upton Grey is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to Upton Grey?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Bathrooms & en suites
- Skirting & floors
- Windows & doors
- Kitchens
- Plot handovers
- Show homes
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Record problems with dated photos
- Act quickly if a seal starts to leak
- Avoid running a DIY bead over the old one
- Raise failed sealant with the developer while you’re covered
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. Somewhere as small as Upton Grey, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
How to get a quote
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Advice
When to call us in Upton Grey
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Any of these means the joints need attention:
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
In and around Upton Grey, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
