Different surfaces, different methods
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
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.

Sheffield Bottom questions
Do you work for landlords with property near Theale station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Sheffield Bottom in your area for new build mastic?

When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep water off fresh sealant until it has cured
- Record problems with dated photos
- Look at the sealant regularly in the first couple of years
- Wipe joints with warm soapy water
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
New build mastic around Sheffield Bottom

The process
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots.

Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
