- Skirting joints opening in the first winter
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
About our new build mastic in Tonge Corner
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We work on windows & doors, kitchens and show homes, and common reasons people get in touch are smeared, uneven beads picked up at snagging and leaking shower tray seals in a new home.
In a village or hamlet like Tonge Corner, 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.
Your job is guaranteed for a year, as with all our work.

Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Act quickly if a seal starts to leak
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.

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

Tonge Corner questions
Do you cover Tonge Corner for new build mastic?
Yes. Our work covers London and the South East, and Tonge Corner is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Will you come out to Tonge Corner?

Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Is it normal for sealant to crack in a new home?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
How do I get a quote for new build mastic in Tonge Corner?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
I’m a tenant. Can you help?
Of course. Check with your landlord; we can send the quote to them too.

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Tonge Corner, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed
