Window & door mastic in Grove, Oxfordshire
Window and door frames in Grove need attention? We cut out the old, prepare the joints and apply the right sealant.
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
- A bead that does not match the frame
Why act early in Grove
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Grove, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.

Window mastic in Grove
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. If you’re dealing with gaps left after new windows were fitted and sealant in the wrong colour for the frame, we can put it right, whatever the surface.
Houses in smaller places like Grove can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

Windows and doors in Grove
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St. John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. For a job in Grove, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Advice
What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Don’t aim a pressure washer at the joints
- Wash the frames with mild soapy water
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
Silicone can’t generally be painted, so mention any painting plans before we start. There are paintable sealants for joints that need it.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Common problems we fix in Grove
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
People usually contact us when they notice something like this:
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
- Draughty joints inside around the window
- Black, perished sealant on frames
Schools such as Millbrook Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Before you book anyone
- How the joint is cleaned and prepared
- Who turns up on the day
- What insurance they hold
- Which colour the sealant will be
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward 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. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
