Why act early in Wickham Bishops
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Wickham Bishops, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

How we handle window mastic in Wickham Bishops
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Typical jobs include old mastic that has gone black or come away and draughty joints inside around the window, on composite doors, timber windows & doors and window sills.
In a village or hamlet like Wickham Bishops, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a 12-month guarantee.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
- Look round the frames every year or so
- Keep paint off silicone joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Your questions about window mastic in Wickham Bishops
Can you help a landlord with a rental near Witham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is Wickham Bishops in your area for window mastic?
Yes, Wickham Bishops is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Can you do upstairs windows?
Yes, in most cases. Access is planned before we start, so mention the height and anything in the way.
How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. In a small place like Wickham Bishops, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
- Mastic that’s falling out in pieces
