What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
New build mastic in Oakshott, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have messy sealant that spoils new finishes and joints pulling apart as timber shrinks, we can help, on plot handovers, kitchens and bathrooms & en suites alike.
Work in a small place like Oakshott just needs the journey and access planning, and once on site, the job is the same as anywhere.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Oakshott questions
Can you help a landlord with a rental near Liss station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Oakshott?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Why has my new-build shower seal failed already?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you insured?
Yes, we’re fully insured.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Clean sealant with mild detergent, not abrasives
- Follow the cure time we give you
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.

What else we do in Oakshott
Do you need new build mastic in Oakshott?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry first.
Common reasons people contact us include:
- New-build shower sealant that has already split
- Worktop and upstand sealant coming away
- Sealant that never bonded to the surface
- Joints pulling apart as timber shrinks
In and around Oakshott, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Oakshott, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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.
