Window mastic in Souldern
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We are often asked to deal with draughts coming in around windows and doors and mastic that’s falling out in pieces, on aluminium frames, window sills and composite doors.
Somewhere as small as Souldern, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a 12-month guarantee.

Why it’s worth doing now in Souldern
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Souldern, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid blasting the frames with a pressure washer
- Do not paint over the silicone
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
Most silicone sealants won’t take paint, so mention any painting plans before we start. We can use a paintable sealant where that matters.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first
- Broken hinges, locks or handles
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What window mastic looks like in Souldern
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Kings Sutton station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Souldern needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

Advice
Signs you need window mastic in Souldern
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Keep an eye out for any of the following:
- Gaps left after new windows were fitted
- Sealant in the wrong colour for the frame
- Old mastic that has gone black or come away
- Whistling draughts around closed windows
For an older house near a landmark such as Church of the Annunciation to the Blessed Virgin Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.
