New build mastic for homes and businesses in Challock
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks rather than sitting on a layer of grit. Typical jobs include frame joints opening as the plaster dries and new-build shower sealant that has already split, on skirting & floors, bathrooms & en suites and kitchens.
In a village or hamlet like Challock, 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.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
When to call us in Challock
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Most people get in touch when they notice one of these:
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
- Internal frame sealant that has split
- Sealant that never bonded to the surface
In and around Challock, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote. In a small place like Challock, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Watch for new gaps as the house dries out
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with straight away
- Keep photos and emails about snagging items
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
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.
