New-build mastic & snagging in Uffington, Oxfordshire
We cover Uffington for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly.
- Sealant work across a run of new homes
- Joints pulling apart as timber shrinks
- Gaps between new skirting and floors
How we handle new build mastic in Uffington
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on kitchens, show homes and bathrooms & en suites, and people most often call us about beads laid onto grit and dust from the build and leaking shower tray seals in a new home.
In a village or hamlet like Uffington, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, in Uffington and everywhere else we cover.

What affects the quote in Uffington
The quote reflects the job in front of us. We look at:
- The number of rooms or windows
- Any mould that needs treating
- How much there is to do
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- How we’d reach the joints
- Photos by email, if that is easy
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before we start.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
- Put sealant faults on your snagging list early
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
Surface by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Common questions in Uffington
Is new build mastic in Uffington guaranteed?
All our work, in Uffington and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover Uffington for new build mastic?
Yes. We work across London and the South East, and Uffington is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
How do I get a quote for new build mastic in Uffington?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What we are called out for in Uffington
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Signs it’s time to call us include:
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
In and around Uffington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- What guarantee comes with the work
- What the cure time is
- Who turns up on the day
- Whether they’re fully insured
Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few pictures and we will give you a straight answer. In a small place like Uffington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours in a single home. In a small place like Uffington, access is generally the main thing to plan. 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.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Clear the area around the work
