What new build mastic looks like in Bagnor
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Newbury station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we handle new build mastic in Bagnor
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. Common call-outs are for internal frame sealant that has split and sealant work across a run of new homes, on kitchens, bathrooms & en suites and show homes.
Older homes in small places like Bagnor often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, it’s backed by our one-year guarantee.

Do you need new build mastic in Bagnor?
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Signs it’s time to call us include:
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
Around Bagnor, as everywhere, new build mastic is only as good as the preparation behind it.
Before booking anyone
- What insurance they hold
- Whether you can choose the colour
- When the joint can take water or movement
- Whether the sealant suits the joint
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 the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Landlords, agents and businesses in Bagnor
We also work for property managers and facilities teams in Bagnor and across West Berkshire. We can quote a run of properties together.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Leave it or put it right?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around Bagnor can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
Why us?
- A 12-month guarantee on all work
- You choose the colour before work begins
- We never seal over old sealant
- More than 20 years in sealant work
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours in a single home. Somewhere as small as Bagnor, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- 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
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Surface by surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
- A tray or bath that isn’t properly supported, until it’s fixed
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

Your questions about new build mastic in Bagnor
Is Bagnor in your area for new build mastic?
Yes, Bagnor is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Newbury station?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
