How we handle window mastic in Godstow
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. If you are dealing with cracked sealant at the sill ends and cold air getting in at the frame edge, we can help, on patio & French doors, aluminium frames and window sills alike.
Homes in small places like Godstow 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 are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Do you need window mastic in Godstow?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Whistling draughts around closed windows
- Mastic that is falling out in pieces
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
Homes close to Church of All Saints include some older properties, and 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
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
Why deal with it now?
The work is quick compared with the damage it prevents: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Godstow, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Rated 4.9 stars on Google
- More than 20 years in sealant work
- Anti-fungal silicone where joints get wet

Window mastic in Godstow: local notes
With historic houses such as Holywell Manor (about 2.7 miles south-east) nearby, there’s older building stock in the area around Godstow as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Managing a site like Wolvercote Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Oxford Parkway station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Should I try it myself first?
Not every job suits DIY: 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 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 fails, we can still redo it.
What sealant work cannot fix
It helps to know what we can’t do:
- Faulty window hardware
- Rotten timber, which needs a joiner first
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Aluminium frames
- uPVC windows
