About our new build mastic in Woodside
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We are often asked to deal with sealant work across a run of new homes and skirting joints opening in the first winter, on kitchens, show homes and windows & doors.
In a village or hamlet like Woodside, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What new build mastic looks like in Woodside
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.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Woodside, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Get a leaking seal dealt with straight away
- Report sealant problems to your builder during the snagging period
- Clean sealant with mild detergent, not abrasives
- Follow the cure time we give you
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
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 the new finishes intact.
What we’re called out for in Woodside
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Any of these means the joints need attention:
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
If you’ve bought a new home near Ascot station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Woodside, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

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.
