Aftercare tips
Looking after new joints is easy:
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
- Keep solvents and bleach off the sealant
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: 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 the visit works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of frames, longer for a whole house. In a small place like Warnborough Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
How to prepare

Advice
Why deal with it now?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. In a small place like Warnborough Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Old sealant always removed completely
- An ARBOMaster approved applicator
- Quality sealants from Arbo and Everbuild
- Full insurance on every job

What affects the quote in Warnborough Green
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Which sealant suits the joint
- Whether there’s mould to deal with
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- The problem you’ve noticed
- The address or postcode of the job
We quote each job on its own. Simply call 0345 464 0079 or send us an email and describe the job and send photos if you have them.
When to call us in Warnborough Green
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Common reasons people contact us include:
- Untidy mastic left by window fitters
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
- Old mastic that has gone black or come away
If you live in an older home near Church of St Mary the Virgin, the joint between an old wall and a newer frame is usually the first place rain gets in.
Before booking anyone
- Is VAT in the price?
- When the joint can take water or movement
- Who turns up on the day

Landlords, agents and businesses in Warnborough Green
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Your questions about window mastic in Warnborough Green
Can you do window mastic in Warnborough Green?
Yes, Warnborough Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
I let a flat near Hook station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
How long will my window job take?
Allow a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Warnborough Green homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Hook station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Robert May's School, its window and door frames need their mastic kept sound, just like a home’s.
