How we handle window mastic in East Boldre
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. If you have cracked internal joints between frame and plaster and mastic that has split away from the wall, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around East Boldre is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, in East Boldre and everywhere else we cover.

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like East Boldre, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

East Boldre: your questions answered
Do you cover smaller places like East Boldre?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Beaulieu Road station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover East Boldre and the rest of Hampshire, along with the rest of our area.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
How do I get a quote for window mastic in East Boldre?

Looking after it afterwards
After the cure time, these simple habits help:
- Keep jet washers away from the mastic
- Keep paint off silicone joints
- Look round the frames every year or so
- Air rooms to keep condensation down around windows
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Signs you need window mastic in East Boldre
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Look out for any of the following:
- Untidy mastic left by window fitters
- Black, perished sealant on frames
- A bead that doesn’t match the frame
- Hard, cracked sealant around windows
For landlords with property near Beaulieu Road station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes most of a day for a typical house, less for a few frames. Somewhere like East Boldre needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

What sealant work can’t fix
To be straight with you, there are a few things sealant won’t fix:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

Frames and glazing around East Boldre
East Boldre is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Beaulieu Village Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
