New build mastic for homes and businesses in Hawkenbury
Across Hawkenbury, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. We work on skirting & floors, show homes and bathrooms & en suites, and common reasons people get in touch are internal frame sealant that has split and cracks appearing as a new home settles.
Around Hawkenbury, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

Signs you need new build mastic in Hawkenbury
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
It’s worth asking for a quote if you see:
- Cracked caulk along new skirting
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
- Worktop and upstand sealant coming away
For new homes near Staplehurst station, it’s worth checking the sealant early, while snags are still fresh.

Common questions in Hawkenbury
Will you come out to Hawkenbury?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Staplehurst station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How do I get a quote for new build mastic in Hawkenbury?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
What happens on the day

- The failed sealant is removed completely, 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.
- Each bead is tooled and the cure times explained.
How to prepare

Advice
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Different surfaces, different methods
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.
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.
Why act early in Hawkenbury
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Where a wall is exposed, as many are in small places like Hawkenbury, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
