About our new build mastic in Hambledon
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. We work on windows & doors, kitchens and skirting & floors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and internal frame sealant that has split.
In a village or hamlet like Hambledon, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Why it’s worth doing now in Hambledon
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Hambledon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in Hambledon
- Any old sealant cut out fully, not covered over
- Colour picked to suit the job

Landlord and commercial work in Hambledon
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Hambledon needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Follow the cure time we give you
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again.

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Whether the job is in Hambledon itself or nearby, the right material for each joint matters as much as a neat finish.

FAQs for Hambledon
Will you come out to Hambledon?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in Hambledon?
Yes, Hambledon is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Is it normal for sealant to crack in a new home?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
