Windows and doors in Great Braxted
Historic houses like Layer Marney Tower (about 4.7 miles north-east) are a reminder that the area around Great Braxted 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Window mastic in Great Braxted
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. Common call-outs are for hard, cracked sealant around windows and cracked sealant at the sill ends, across window sills, aluminium frames and uPVC windows.
In a village or hamlet like Great Braxted, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Quotes for window mastic in Great Braxted
There’s no set price list, because no two jobs are the same. What we look at:
- How much there is to do
- Access and height
- Which sealant suits the joint
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That is why we ask about the job first.
Helping us quote
To make quoting easier, let us know:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Air rooms to keep condensation down around windows
- Keep paint off silicone joints
- Walk round the house once a year and look at the joints
- Keep timber frames painted
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Great Braxted, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

Related advice
Signs you need window mastic in Great Braxted
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
People generally contact us when they notice one of these:
- Gaps between the frame and the inside reveal
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- What insurance they hold
- The length of the guarantee
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Common questions in Great Braxted
I let a flat near Witham station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Great Braxted?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before work begins.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Do you work on first-floor windows?
Usually, yes. We plan safe access before the job, so mention the height and anything in the way.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Does the work come with a guarantee?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Great Braxted, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
