Window mastic in Clifton Hampden, done properly
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include water coming in at the bottom corners of a door and gaps left after new windows were fitted, across window sills, aluminium frames and composite doors.
Mastic can only go onto a dry, clean joint, so window work in Clifton Hampden is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same 12-month guarantee.

When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. It will not solve:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- A sash or casement that will not close properly
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

Leave it or put it right?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Clifton Hampden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of frames, longer for a whole house. Somewhere as small as Clifton Hampden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.
FAQs for Clifton Hampden
Will you come out to Clifton Hampden?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do window mastic in Clifton Hampden?
Yes. We work across London and the South East, and Clifton Hampden is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across Oxfordshire.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Common problems we fix in Clifton Hampden
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
If you live in an older home near Church of St Michael and All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Is VAT in the price?
- Whether they’re fully insured
- Whether the sealant suits the joint
- How hidden problems are handled
What window mastic looks like in Clifton Hampden
With historic houses such as Clifton Hampden Manor (about 0.1 miles east) nearby, there’s older building stock in the area around Clifton Hampden as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Culham station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Clifton Hampden Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
