New build mastic around Marshborough
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Sandwich station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we handle new build mastic in Marshborough
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that’s what rushed new-build sealant normally lacks. If you have gaps behind new kitchen upstands and sealant work across a run of new homes, we can put it right.
Work in a small place like Marshborough just needs the journey and access planning, and the work itself is the same as on any site.
Your job is guaranteed for a year, as with all our work.

We will always be straight with you, so here’s what new sealant will not do:
- Broken tiles or a split tray

- Movement caused by a poorly fitted tray or bath
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Signs you need new build mastic in Marshborough
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Signs it’s time to call us include:
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Joints pulling apart as timber shrinks
In and around Marshborough, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Marshborough
Do you work for landlords with property near Sandwich station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Do you cover smaller places like Marshborough?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
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.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Who should fix failed sealant in a new build?
Start with the builder if you’re in the snagging or warranty period. Once that’s done, or if they won’t put it right, we will cut it out and reseal it.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Marshborough, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Leave it or put it right?
A hairline gap at a skirting can wait, but water getting through can’t. If you are unsure which you have, phone 0345 464 0079 or email us with pictures and we’ll tell you. Where a wall is exposed, as many are in small places like Marshborough, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What you get with us
- Sealant colour chosen to suit
- White, clear, grey or another colour, product permitting

Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered.
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.
