New build mastic for homes and businesses in Gilston
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have kitchen sealant that has pulled off the wall and sealant work across a run of new homes, we can put it right.
Around Gilston, 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.
Each job carries a 12-month guarantee.

Signs you need new build mastic in Gilston
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Common reasons people contact us include:
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
For new homes near Harlow Town station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Which colour the sealant will be
- Who does the work, and how experienced they are
- How long to leave it before use
- Whether VAT is included
When something else is needed
New sealant cannot fix everything, and we’ll tell you before we start. It won’t solve:
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Bathrooms & en suites
- Windows & doors

- Skirting & floors
- Show homes
- Plot handovers
How to look after the new joints
A little care helps the new joints last. We recommend:
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
- Get a leaking seal dealt with right away
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What the job involves on each surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Leave it or put it right?
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 Gilston, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Tidy, careful work
- Domestic, commercial and hotel work
- Sanitary silicone with an anti-fungal additive in wet areas
- A 12-month guarantee on all work

New build mastic around Gilston
Gilston is part of Harlow, one of the post-war new towns. Harlow has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Gilston, as everywhere, new build mastic is only as good as the preparation behind it.
