New Build Mastic in Ashingdon
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Ashingdon and across Essex. Fully insured, ARBOMaster approved and guaranteed for a year.
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you’re covered
- Do not seal over failed sealant yourself
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
How we handle new build mastic in Ashingdon
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 work on bathrooms & en suites, skirting & floors and plot handovers, and common reasons people get in touch are gaps opening as the house dries out and settles and sealant applied over dusty or wet surfaces.
If you’ve bought a new home in or near Ashingdon, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Whatever the size of the job, you get the same 12-month guarantee in Ashingdon and across Essex.

Do you need new build mastic in Ashingdon?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Any of these means the joints need attention:
- Gaps between new skirting and floors
- Sealant that never bonded to the surface
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
Around Ashingdon, as everywhere, new build mastic is only as good as the preparation behind it.

What happens on the day
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work usually takes anything from a few hours to several days, depending on the number of plots. A visit to Ashingdon is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

Why it’s worth doing now in Ashingdon
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Homes in smaller places like Ashingdon 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.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
