Questions from Hinton Ampner
Can you do window mastic in Hinton Ampner?
Yes, Hinton Ampner is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
What guarantee comes with window mastic in Hinton Ampner?
All our work, in Hinton Ampner and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How many windows can you do in a day?
A handful of frames is a short visit. You will get a timescale with the quote.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
How we handle window mastic in Hinton Ampner
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on window sills, composite doors and aluminium frames, and people most often call us about hard, cracked sealant around windows and cracked sealant at the sill ends.
Outdoor sealant needs dry, clean surfaces, so work on frames around Hinton Ampner is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Why act early in Hinton Ampner
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Hinton Ampner can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why Hinton Ampner customers choose us
- Every job guaranteed for a year
- We leave the area clean and tidy
- Colour picked to suit the job
- White, clear, grey or coloured to suit, where the product allows
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Condensation trapped between the panes
- A frame that has rotted at the joint
- Damp coming through the wall itself rather than the frame joint
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.

Window mastic in Hinton Ampner: local notes
Historic houses like Hinton Ampner House (about 0.3 miles south) are a reminder that the area around Hinton Ampner has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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 site and facilities teams at buildings such as Cheriton Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What we’re called out for in Hinton Ampner
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That is what backing rod is for.
The problems people usually mention when they call include:
- Cold air getting in at the frame edge
- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Comparing quotes
- What insurance they hold
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- How long to leave it before use
Different surfaces, different methods
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
