What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
About our new build mastic in Woodmancote
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Common call-outs are for frame joints opening as the plaster dries and new-build shower sealant that has already split, on skirting & floors, show homes and bathrooms & en suites.
In a village or hamlet like Woodmancote, 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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Aftercare tips
A little care helps the new joints last. Our advice:
- Use the extractor fan every time you shower
- Act quickly if a seal starts to leak
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
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.
The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours in a single home, including the tidy-up. In a small place like Woodmancote, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

What else we do in Woodmancote
Do you need new build mastic in Woodmancote?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
People normally contact us after spotting one of these:
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
- Sealant applied over dusty or wet surfaces
In and around Woodmancote, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether they’re fully insured
- How much experience the applicator has
- What the cure time is
What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Woodmancote, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

DIY versus a professional finish
If you do try it yourself, take your time over the 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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What new build mastic looks like in Woodmancote
Woodmancote is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Southbourne station, the sealant around baths, showers and frames is worth checking in the first year or two.
