How we handle window mastic in Headington Quarry
Homes in Headington Quarry have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include a bead that doesn’t match the frame and hard, cracked sealant around windows, across composite doors, timber windows & doors and window sills.
Houses in smaller places like Headington Quarry can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
Whatever the size of the job, you get the same 12-month guarantee in Headington Quarry and across Oxfordshire.

What window mastic looks like in Headington Quarry
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. Historic houses like Holywell Manor (about 2 miles west) are a reminder that the area around Headington Quarry has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Oxford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Holy Trinity Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Headington Quarry Foundation Stage School, its window and door frames need their mastic kept sound, just like a home’s.

What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The size of the job
- Any mould that needs treating
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Whether it has been sealed before
- Where the property is
- A few pictures by email, if you can
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or email us.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Different surfaces, different methods
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Why act early in Headington Quarry
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In an older home around Headington Quarry, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. A visit to Headington Quarry is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
