Window Mastic in Swalcliffe
Problem with your window and door frames in Swalcliffe? We cut out the old, prepare the joints and apply the right sealant.
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
When to call us in Swalcliffe
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Common reasons people contact us include:
- Cracked or shrunken mastic around the frame
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Black, perished sealant on frames
Homes close to Church of St Peter and St Paul include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle window mastic in Swalcliffe
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. If you have a bead that doesn’t match the frame and cold air getting in at the frame edge, we can help, whatever the surface.
Homes in small places like Swalcliffe often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

What we do, step by step
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. In a small place like Swalcliffe, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Before we arrive
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Questions from Swalcliffe
Will you come out to Swalcliffe?

What guarantee comes with window mastic in Swalcliffe?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Oxfordshire.
How much does window mastic cost in Swalcliffe?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Swalcliffe homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Broughton Castle (about 2.5 miles east) are a reminder that the area around Swalcliffe has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Sibford School, larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Air rooms to keep condensation down around windows
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Leave it or put it right?
Choosing the product is half the job. 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. Around Swalcliffe, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
