New build mastic for homes and businesses in Worth
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you have joints pulling apart as timber shrinks and plot mastic for developers ahead of handover, we can put it right, whatever the surface.
In and around Worth, floors range from older timber boards to tiles and newer finishes, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
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.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. Parking around Worth is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Advice
Do you need new build mastic in Worth?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
People normally contact us when they notice something like this:
- Gaps between new skirting and floors
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
For new homes near Three Bridges station, it’s worth checking the sealant early, while snags are still fresh.
Before booking anyone
- What guarantee comes with the work
- How hidden problems are handled
- Whether you can choose the colour
- Is the old sealant removed completely?
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, phone 0345 464 0079 or drop us an email with photos and we will give you a straight answer. Homes in smaller places like Worth can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why Worth customers choose us
- Sealant colour chosen to suit
- Any old sealant cut out fully, not covered over

What new build mastic looks like in Worth
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Worth is part of Crawley, one of the post-war new towns. Crawley has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Newer homes need snagging; older ones need their joints renewing.
Around Worth, as everywhere, new build mastic is only as good as the preparation behind it.

Worth: your questions answered
Will you come out to Worth?
Yes. Worth is within the area we cover, which takes in towns, villages and rural addresses. We work across 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 Three Bridges station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Should I go to my builder first?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

We seal show-home bathrooms, kitchens and frames to a tidy standard. We’ll plan around viewing times.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep pictures and emails about snagging items
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
