How we handle new build mastic in Headington
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. Common call-outs are for sealant work across a run of new homes and worktop and upstand sealant coming away, on skirting & floors, kitchens and show homes.
Where new homes go up in smaller places like Headington, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Parking around Headington is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any tricky access
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts

Advice
When to call us in Headington
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
Signs it’s time to call us include:
- Sealant work across a run of new homes
- Messy sealant that spoils new finishes
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Oxford station, the sealant around baths, showers and frames is worth checking in the first year or two.

FAQs for Headington
Will you come out to Headington?
Yes. Headington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Headington in your area for new build mastic?
Yes. We work across London and the South East, and Headington is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Do you use white or clear sealant?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Looking after it afterwards
Looking after new joints is easy:
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
- Look at the sealant regularly in the first couple of years
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
What happens if it’s left?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Around Headington, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- A choice of colours where the product allows
- Anti-fungal silicone where joints get wet
