About our new build mastic in Littleworth
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you have kitchen sealant that has pulled off the wall and internal frame sealant that has split, we can put it right, whatever the surface.
In a village or hamlet like Littleworth, 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.
There’s a 12-month guarantee on every job, whatever its size.

When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Movement caused by a poorly fitted tray or bath
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

Landlords, agents and businesses in Littleworth
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For a village or hamlet like Littleworth, 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 look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

How we quote for new build mastic
We quote each job individually. These are the things that affect it:
- Whether the work is at height
- Which sealant suits the joint
- The amount of work
- The number of rooms or windows
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Photos by email, if that is easy
- The type of property
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Do you need new build mastic in Littleworth?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Most people get in touch after spotting something like this:
- Joints pulling apart as timber shrinks
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
In and around Littleworth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Whether you can choose the colour
- How long to leave it before use

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
