New build mastic in Great Horkesley
Across Great Horkesley, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. If you’re dealing with gaps between new skirting and floors and shower seals failing in the first year or two, we can help, whatever the surface.
In smaller places like Great Horkesley, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
A one-year guarantee comes as standard.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Avoid running a DIY bead over the old one
- Record problems with dated photos
- Get a leaking seal dealt with straight away
- Open a window or run the fan after bathing
Watch the joints as the house settles. Small gaps can appear as the house dries.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.

- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.

What we are called out for in Great Horkesley
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.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that never bonded to the surface
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Colchester station, the sealant around baths, showers and frames is worth checking in the first year or two.

How much does new build mastic cost in Great Horkesley?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
Do you have insurance?
Yes. Mr Mastic is fully insured.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
