New build mastic in Tangley, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We’re often asked to deal with kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, on windows & doors, bathrooms & en suites and plot handovers.
In a village or hamlet like Tangley, 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.
Whatever the size of the job, it’s backed by our one-year guarantee.

Your questions about new build mastic in Tangley
Can you help a landlord with a rental near Andover station?

Do you cover smaller places like Tangley?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work through snagging lists?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved and we’ll quote.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
What colour sealant will you use?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
How much does new build mastic cost in Tangley?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
What the job involves on each surface
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.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- The number and length of the joints
- Any mould that needs treating
- Any working-time requirements on site
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- Where the job is, and your postcode
Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job, and photos are welcome.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Record problems with dated photos
- Check bath and shower seals every few months as the house settles
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Why act early in Tangley
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can call 0345 464 0079 or email us with a few photos and we’ll tell you. Where a wall is exposed, as many are in small places like Tangley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
