Common reasons people contact us include:
- Cracked caulk along new skirting
- Shower seals failing in the first year or two
- Second-fix sealing on new plots

New build mastic in Wittensford
We work in new homes and on new-build sites across Wittensford. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on bathrooms & en suites, kitchens and plot handovers, and the jobs we see most are gaps opening as the house dries out and settles and leaking shower tray seals in a new home.
In a village or hamlet like Wittensford, 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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.
What we seal
- Plot handovers
- Kitchens
- Show homes
- Skirting & floors
- Bathrooms & en suites
- Windows & doors
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Follow the cure time we give you
- Use the extractor fan every time you shower
- Get a leaking seal dealt with straight away
- Put sealant faults on your snagging list early
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.
Wittensford: your questions answered
Do you cover smaller places like Wittensford?
Yes. Wittensford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Ashurst New Forest station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
How much does new build mastic cost in Wittensford?
Size, access and the old material all affect the cost. Ask us for a quote.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. In a small place like Wittensford, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Clear items away from the joints we are working on

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
