What affects the quote in Upton
Jobs vary more than people expect. What affects the quote:
- The number and length of the joints
- The number of rooms or windows
- Working hours on commercial sites
- Whether the work is at height
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.
About our new build mastic in Upton
Across Upton, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. We work on windows & doors, kitchens and show homes, and common reasons people get in touch are untidy sealant flagged on a snagging list and cracked sealant around new window and door frames.
In smaller places like Upton, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
Our work is backed for twelve months, in Upton and everywhere else we cover.

What new build mastic looks like in Upton
Upton is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Upton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Upton is about 1 mile south-west of Broadstairs, in Kent. Jobs in Upton get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Across Kent, we cover 922 places, and Upton is one of them. There’s also a page for Chelmsford, about 48 miles away.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
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.
Signs you need new build mastic in Upton
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The problems people usually mention when they call are:
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Leaking shower tray seals in a new home
If you’ve bought a new home near Broadstairs station, the sealant around baths, showers and frames is worth checking in the first year or two.

- When the joint can take water or movement

How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. For a job in Upton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Your questions about new build mastic in Upton
Is Upton in your area for new build mastic?
Yes, Upton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
I let a flat near Broadstairs station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
My new home is still under warranty. Should I contact you?
Start with the builder if you’re in the snagging or warranty period. If it isn’t resolved, we will cut it out and reseal it.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you guarantee your work?
Yes. Every job comes with our 12-month guarantee.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
