New build mastic in Fulmer
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Typical jobs include second-fix sealing on new plots and messy sealant that spoils new finishes, across windows & doors, kitchens and skirting & floors.
Around Fulmer, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Other services in Fulmer
Landlords, agents and businesses in Fulmer
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Common problems we fix in Fulmer
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry first.
Signs it’s time to call us include:
- Internal frame sealant that has split
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
For new homes near Gerrards Cross station, it’s worth checking the sealant early, while snags are still fresh.

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. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Your warranty claim itself, which is between you and the builder
- Damaged fittings that need replacing
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Fulmer: your questions answered
Is Fulmer in your area for new build mastic?
Yes, Fulmer is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Gerrards Cross station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Do you work through snagging lists?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
How much does new build mastic cost in Fulmer?
Size, access and the old material all affect the cost. Ask us for a quote.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. In a small place like Fulmer, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
