- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
- Cracked or shrunken mastic around the frame
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not aim a pressure washer at the joints
- Keep paint off silicone joints
- Look round the frames every year or so
- Make sure the drainage slots are not blocked
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
How we handle window mastic in Fulbrook
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. If you have mastic that has split away from the wall and rushed sealant from a window installation, we can help, whatever the surface.
Somewhere as small as Fulbrook, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months.

Window mastic in Fulbrook: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Minster Lovell Hall (about 4.2 miles east) nearby, there’s older building stock in the area around Fulbrook as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of Saint James the Great, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Burford Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Do you need window mastic in Fulbrook?
Water runs down the glass onto the sill, 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.
People generally contact us after spotting one of these:
- Cracked sealant at the sill ends
- Rain getting in at the frame or under the sill
- Mastic that’s falling out in pieces
- Gaps left after new windows were fitted
Letting a property close to Shipton station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- How much experience the applicator has
- Whether all the old sealant comes out first
- Which colour the sealant will be
- What the cure time is
What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
What happens if it’s left?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Older cottages and farmhouses around Fulbrook can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

- The product the joint needs
- Mould in or behind the old joints

FAQs for Fulbrook
Can you help a landlord with a rental near Shipton station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Fulbrook in your area for window mastic?
Yes, Fulbrook is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
