How we handle new build mastic in Highsted
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. Common call-outs are for skirting joints opening in the first winter and frame joints opening as the plaster dries, across skirting & floors, show homes and plot handovers.
Older homes in small places like Highsted often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work is covered by a 12-month guarantee.

What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Highsted, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any tricky access
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit

- Cracked trays, tiles or worktops

How the job changes by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
FAQs for Highsted

Yes. We work across London and the South East, and Highsted is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.

Where do you work from?

How much does new build mastic cost in Highsted?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Do you need new build mastic in Highsted?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Common reasons people contact us include:
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
Around Highsted, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- How long the guarantee is
- Who turns up on the day
- Which sealant they’ll use, and why
- What the cure time is
Aftercare tips
To keep the joints looking good and working properly:
- Put sealant faults on your snagging list early
- Record problems with dated photos
- Get a leaking seal dealt with right away
- Don’t seal over failed sealant yourself
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
