Leave it or put it right?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Bramshott, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why choose Mr Mastic in Bramshott

Window mastic in Bramshott
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Typical jobs include mastic that’s falling out in pieces and whistling draughts around closed windows, on timber windows & doors, aluminium frames and uPVC windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Bramshott is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same one-year guarantee in Bramshott and across Hampshire.

Questions from Bramshott
I let a flat near Liphook station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Bramshott in your area for window mastic?
Yes. We work across London and the South East, and Bramshott is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before we start.
Do you guarantee window mastic?
Yes. Every job comes with our 12-month guarantee, and we are fully insured.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Look round the frames every year or so
- Wash the frames with mild soapy water
- Don’t aim a pressure washer at the joints
- Do not use solvent cleaners on the joint
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

What sealant work cannot fix
It helps to know what we can’t do too:
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
- Worn gaskets, brush seals or a door that has dropped
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- uPVC windows
- Timber windows & doors

How it works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job normally takes a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Somewhere like Bramshott needs a little journey planning: 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.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

What affects the cost of window mastic
We quote each job individually. These are the things that affect it:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
When you call or email, these details help:
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Whether it’s a home or a business
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
What we are called out for in Bramshott
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Signs it’s time to call us include:
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

Window mastic in Bramshott: local notes
