How we handle window mastic in Abbotts Barton
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on composite doors, patio & French doors and timber windows & doors, and the jobs we see most are mastic that has split away from the wall and gaps between the frame and the inside reveal.
Many houses in smaller places like Abbotts Barton have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why act early in Abbotts Barton
The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. In a smaller place like Abbotts Barton, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Take a look at how sealant jobs are priced and our reviews.
Surface by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Composite doors
Front doors take the weather head on. Those corners get the most care.
Common questions in Abbotts Barton
Do you work for landlords with property near Winchester station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover Abbotts Barton for window mastic?
Yes, Abbotts Barton is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Is the new sealant paintable?
Not usually, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can you do upstairs windows?
Yes, in most cases. Access is planned before work begins, so mention the height and anything in the way.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Abbotts Barton, along with the rest of our area.
Frames and glazing around Abbotts Barton
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as St Bede Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Bartholomew's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Abbotts Barton
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Look out for any of the following:
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
If you let a flat or house near Winchester station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- Are they insured?
- What happens if they find a problem under the old sealant
- How much experience the applicator has
- What product goes in the joint
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames in most cases. A visit to Abbotts Barton is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- 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
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Clear items away from the joints we’re working on
