How we handle new build mastic in Beauworth
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 seal that is letting water through needs doing now. Typical jobs include shower seals failing in the first year or two and worktop and upstand sealant coming away, on windows & doors, show homes and plot handovers.
Work in a small place like Beauworth just needs the journey and access planning, and once on site, the job is the same as anywhere.
Each job carries a 12-month guarantee.

Common problems we fix in Beauworth
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
These are the problems we’re asked about most:
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Second-fix sealing on new plots
Whether the job is in Beauworth itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- How hidden problems are handled
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, 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.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Older cottages and farmhouses around Beauworth can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Beauworth questions
What guarantee comes with new build mastic in Beauworth?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Beauworth in your area for new build mastic?
Yes, Beauworth is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long will you be here?
As a guide, most jobs take a few hours in a single home. Larger jobs naturally take longer, and we will say how long yours will take.
Why has my new-build shower seal failed already?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across Hampshire.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with pictures if you can and we’ll give you a quote. We’ll tell you if anything on it is not a sealant job.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like Beauworth, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
