New build mastic in Highbridge, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you’re dealing with shower seals failing in the first year or two and gaps behind new kitchen upstands, we can put it right.
Around Highbridge, 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Highbridge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit

What affects the quote in Highbridge
We don’t publish a price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- Working hours on commercial sites
- The number and length of the joints
- How easy the joints are to reach
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Photos by email, if that’s easy
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Where a wall is exposed, as many are in small places like Highbridge, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
