How we handle new build mastic in Britwell
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on kitchens, windows & doors and bathrooms & en suites, and people most often call us about internal frame sealant that has split and skirting joints opening in the first winter.
For a new home in or near Britwell, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Questions from Britwell
Do you work for landlords with property near Burnham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Britwell?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
How long before the joint can be used?
Cure times vary by product. We tell you how long to leave it before we go.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid running a DIY bead over the old one
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
Do not stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification. We seal bathrooms, kitchens, frames and floors as agreed.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
New homes and floors in Britwell
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. A visit to Britwell is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed
