About our window mastic in Church Enstone
Around Church Enstone we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Common call-outs are for old mastic that has gone black or come away and white mastic on grey or black frames, across window sills, aluminium frames and timber windows & doors.
Somewhere as small as Church Enstone, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You get a 12-month guarantee, the same in Church Enstone as everywhere else we work.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of frames, longer for a whole house. Somewhere as small as Church Enstone, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work

FAQs for Church Enstone

Can you reach windows above the ground floor?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Is there any odour?
Possibly a little. It fades as the sealant cures.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Why act early in Church Enstone
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Church Enstone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Your quote is based on your job. We take into account:
- The amount of work
- Any working-time requirements on site

What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Composite doors
Front doors take the weather head on. Those corners get the most care.
Windows and doors in Church Enstone
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Charlbury station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Church of St Kenelm, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Enstone Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
