Window mastic in Norham Manor, done properly
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Typical jobs include gaps where the sill meets the wall and draughty joints inside around the window, on patio & French doors, window sills and timber windows & doors.
Many houses in smaller places like Norham Manor have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for a handful of frames, longer for a whole house. Parking around Norham Manor is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Norham Manor homes and the weather
Historic houses like Holywell Manor (about 0.7 miles south-east) are a reminder that the area around Norham Manor 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. 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.
Holywell Manor, about 0.7 miles south-east, is one of the historic houses in the wider area around Norham Manor, and older homes nearby need a sealant that suits their walls. Schools such as Wychwood School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.

When something else is needed
In fairness, there are a few things sealant will not fix:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Homes in smaller places like Norham Manor can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.

When to call us in Norham Manor
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Common reasons people contact us include:
- Leaking joints at the ends of sills
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
- Untidy mastic left by window fitters
If you let a flat or house near Oxford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

- Which sealant they’ll use, and why
- Whether they seal over old material or remove it

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Clean frames with a soft cloth and soapy water
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
- Check the mastic once a year
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
