About our window mastic in Little London
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you’re dealing with cracked or shrunken mastic around the frame and rushed sealant from a window installation, we can help, whatever the surface.
Somewhere as small as Little London, 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.
You get a one-year guarantee, the same in Little London as everywhere else we work.

What affects the quote in Little London
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether the work is at height
- The number and length of the joints
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Where the job is, and your postcode
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
For window mastic in Little London, ring 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Older cottages and farmhouses around Little London can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What you get with us
- Tidy, careful work
- Old sealant always removed completely
- Approved under the ARBOMaster scheme
- A choice of colours where the product allows

Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Common questions in Little London
Will you come out to Little London?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Andover station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Little London 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 check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Move anything stored near the joints

Related advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t paint over the silicone
- Make sure the drainage slots are not blocked
- Avoid harsh chemicals near the mastic
- Check the mastic once a year
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
Windows and doors in Little London
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Andover station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Christ Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Smannell and Enham Church of England (Aided) Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
