New-build mastic & snagging in Ducklington, Oxfordshire
New-build sealant joints in Ducklington need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How we handle new build mastic in Ducklington
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We’re often asked to deal with leaking shower tray seals in a new home and messy sealant that spoils new finishes, across show homes, windows & doors and kitchens.
Older homes in small places like Ducklington often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
- Act quickly if a seal starts to leak
- Record problems with dated pictures
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

How we quote for new build mastic
Your quote is based on your job. We take into account:
- How easy the joints are to reach
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Signs you need new build mastic in Ducklington
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.
Any of these means the joints need attention:
- Internal frame sealant that has split
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
Whether the job is in Ducklington itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- Is the old sealant removed completely?
- What the cure time is
- What happens if they find a problem under the old sealant
- Whether you can choose the colour

Why deal with it now?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Ducklington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Ducklington questions
What guarantee comes with new build mastic in Ducklington?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Ducklington?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
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’ll tell you what we’re using.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How do I get a quote for new build mastic in Ducklington?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home, and the area is left clean. For a village or hamlet like Ducklington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
