How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- How easy the joints are to reach
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- What’s wrong with the joints now
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
About our new build mastic in Merstone
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on plot handovers, bathrooms & en suites and skirting & floors, and common reasons people get in touch are smeared, uneven beads picked up at snagging and sealant that never bonded to the surface.
Somewhere as small as Merstone, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A one-year guarantee comes with the work, just as it does everywhere we cover.

New build mastic in Merstone: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Merstone, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Shanklin station, the sealant around baths, showers and frames is worth checking in the first year or two.

Looking after it afterwards
After the cure time, these simple habits help:
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Wait for the cure time before using a resealed shower
- Record problems with dated photos
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
Why act early in Merstone
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Merstone, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
