Window mastic in Uffington, done properly
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We work on patio & French doors, composite doors and uPVC windows, and the jobs we see most are mastic that’s falling out in pieces and water coming in at the bottom corners of a door.
Outdoor sealant needs dry, clean surfaces, so work on frames around Uffington is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Uffington needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

Common questions in Uffington
Will you come out to Uffington?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on window mastic in Uffington?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before we start.
How much does window mastic cost in Uffington?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
What we seal
- Aluminium frames
- Patio & French doors
- Timber windows & doors
- uPVC windows
- Composite doors
- Window sills
Can I do it myself?
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 doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
For landlords and businesses
If you manage several properties in or around Uffington, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Windows and doors in Uffington
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Ashdown House (about 4.8 miles south) are a reminder that the area around Uffington 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’s traditional sand mastic.
For site and facilities teams at buildings such as Uffington Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Uffington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Signs you need window mastic in Uffington
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Look out for these signs:
- Cracked or shrunken mastic around the frame
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
- Mastic that is falling out in pieces
If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What to look for in a quote
- Is VAT in the price?
- Whether the sealant suits the joint
- How hidden problems are handled
- Whether all the old sealant comes out first
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Air rooms to keep condensation down around windows
- Avoid blasting the frames with a pressure washer
- Look round the frames every year or so
- Wash the frames with mild soapy water
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
