New build mastic in Swinford
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you have worktop and upstand sealant coming away and untidy sealant flagged on a snagging list, we can help.
In a village or hamlet like Swinford, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Common questions in Swinford
Is Swinford within the area you cover?
Yes. Swinford 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.
Can you help a landlord with a rental near Hanborough station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
How long does the job take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
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.

We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Put sealant faults on your snagging list early
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Keep water off fresh sealant until it has cured
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
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 over time.
What we are called out for in Swinford
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.
Any of these means the joints need attention:
- Frame joints opening as the plaster dries
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
Around Swinford, as everywhere, new build mastic is only as good as the preparation behind it.

Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
