How we handle new build mastic in Waltham Chase
Across Waltham Chase, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on bathrooms & en suites, show homes and skirting & floors, and common reasons people get in touch are internal frame sealant that has split and sealant that never bonded to the surface.
Somewhere as small as Waltham Chase, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
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.

Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

Advice
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Waltham Chase, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why us?
- Homes, businesses and hotels
- Neat joints and a tidy finish
- A 12-month guarantee on all work
- White, clear, grey or another colour, product permitting

FAQs for Waltham Chase
Do you cover Waltham Chase for new build mastic?
Yes. We work across London and the South East, and Waltham Chase is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
I let a flat near Botley station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
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 pictures.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

Aftercare tips
Aftercare is simple:
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
Do not stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
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.
What we’re called out for in Waltham Chase
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
It’s worth asking for a quote if you see:
- Frame joints opening as the plaster dries
- Sealant applied over dusty or wet surfaces
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
Around Waltham Chase, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Whether they seal over old material or remove it
- What the cure time is
- How hidden problems are handled
- Are they insured?
