About our window mastic in Maudlin
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on aluminium frames, timber windows & doors and uPVC windows, and the jobs we see most are cracked sealant at the sill ends and gaps left after new windows were fitted.
Around Maudlin, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our one-year guarantee in Maudlin and across West Sussex.

Maudlin: your questions answered
Is Maudlin within the area you cover?
Yes. Maudlin is within the area we cover, which takes in towns, villages and rural addresses. 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 Chichester station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do you have insurance?
Yes. We are fully insured.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
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 do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
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. We use products from Arbo and Everbuild.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Landlord and commercial work in Maudlin
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
When to call us in Maudlin
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
It’s worth asking for a quote if you see:
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- A bead that does not match the frame
Rented homes near Chichester station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before booking
- Whether all the old sealant comes out first
- Which colour the sealant will be
- How the joint is cleaned and prepared
- Is VAT in the price?
The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Maudlin, the journey is planned in advance: 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 how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Mention if the joints have been sealed before

Advice
How the job changes by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.

Windows and doors in Maudlin
Historic houses like Goodwood House (about 1.5 miles north) are a reminder that the area around Maudlin has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near The Parish Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as The March CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
