About our new build mastic in Henton
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant generally lacks. We work on skirting & floors, windows & doors and bathrooms & en suites, and the jobs we see most are sealant work across a run of new homes and frame joints opening as the plaster dries.
In a village or hamlet like Henton, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Joints and finishes in Henton homes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Princes Risborough station, it’s worth checking the sealant early, while snags are still fresh.

Henton questions
Can you do new build mastic in Henton?
Yes. Our work covers London and the South East, and Henton is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
I let a flat near Princes Risborough station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What colour sealant will you use?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
What happens if it’s left?
A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Henton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Henton customers choose us
- Fully insured
- Tidy, careful work
- Anti-fungal sanitary silicone in wet areas

How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Henton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- 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.
Preparing for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will take it from there.

What we’re called out for in Henton
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Signs it’s time to call us include:
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
Around Henton, as everywhere, new build mastic is only as good as the preparation behind it.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
