Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Can new window sealant be painted?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Does the work come with a guarantee?
Yes. Our 12-month guarantee covers every job, inside or out.
About our window mastic in Sarsden
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on aluminium frames, uPVC windows and window sills, and the jobs we see most are old mastic that has gone black or come away and rushed sealant from a window installation.
Around Sarsden, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep paint off silicone joints
- Don’t aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Clean frames with a soft cloth and soapy water
Most silicone sealants will not take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes most of a day for a typical house, less for a few frames. In a small place like Sarsden, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Keep children and pets away from the work area
- Clear the area around the work
- Tell us if parking is tricky

Honest limits
A few problems are outside what sealant work can do:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes

Common problems we fix in Sarsden
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
- A bead that doesn’t match the frame
- Black, perished sealant on frames
If you let a flat or house near Kingham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Windows and doors in Sarsden
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Chastleton House (about 4.3 miles north-west) are a reminder that the area around Sarsden has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Chipping Norton School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Sarsden
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Sarsden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
