About our window mastic in Milton-under-Wychwood
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for hard, cracked sealant around windows and black, perished sealant on frames, across window sills, uPVC windows and timber windows & doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Milton-under-Wychwood is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

FAQs for Milton-under-Wychwood
Is Milton-under-Wychwood in your area for window mastic?
Yes. Our work covers London and the South East, and Milton-under-Wychwood is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you work for landlords with property near Shipton station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Can you do upstairs windows?
Yes, in most cases. We plan safe access before the job.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
How many windows can you do in a day?
Allow a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Looking after it afterwards
So the new joints stay in good condition:
- Check the mastic once a year
- Clean frames with a soft cloth and soapy water
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
Silicone cannot generally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Milton-under-Wychwood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

For landlords 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.
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote, and we’re fully insured for the work.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Milton-under-Wychwood 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.

What affects the quote in Milton-under-Wychwood
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You will have a clear quote before we start.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

- Window sills
- Timber windows & doors

What we’re called out for in Milton-under-Wychwood
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Common reasons people contact us include:
- Untidy mastic left by window fitters
- Cracked or shrunken mastic around the frame
- A bead that does not match the frame
- Draughts coming in around windows and doors
In the older streets around Church of St Simon and St Jude, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
