Window mastic for homes and businesses in Middleton Stoney
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have old mastic that has gone black or come away and cold air getting in at the frame edge, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Middleton Stoney is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by our one-year guarantee.

Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.

Common questions in Middleton Stoney
Is Middleton Stoney within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Heyford station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
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.
Why act early in Middleton Stoney
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Older cottages and farmhouses around Middleton Stoney can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

When to call us in Middleton Stoney
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
These are the problems we’re asked about most:
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
- Black, perished sealant on frames
- Damp patches on the reveal after heavy rain
For landlords with property near Heyford station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- Which sealant they’ll use, and why
- What happens if the job turns out different
- Whether they seal over old material or remove it
- Is VAT in the price?

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. For a village or hamlet like Middleton Stoney, 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, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
