Lullington homes and the weather
Lullington is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Alfriston School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Church of St. Andrew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

About our window mastic in Lullington
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on window sills, aluminium frames and patio & French doors, and common reasons people get in touch are draughty joints inside around the window and mastic that’s falling out in pieces.
Mastic can only go onto a dry, clean joint, so window work in Lullington is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with a one-year guarantee, wherever you are in East Sussex.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Somewhere like Lullington needs a little journey planning: let us know about lanes, gates and parking. 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.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Common problems we fix in Lullington
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
Most people get in touch when they notice something like this:
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
- Black, perished sealant on frames
- Cold air getting in at the frame edge
For landlords with property near Berwick (Sussex) station, renewing tired window mastic between tenants heads off draught and damp complaints.
Before booking anyone

- What guarantee comes with the work
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. Neutral-cure sealant is the safe choice.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
FAQs for Lullington
Will you come out to Lullington?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Berwick (Sussex) station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Can you reach windows above the ground floor?
Generally, yes. Access is planned before work begins, so mention the height and anything in the way.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
How long will my window job take?
A few frames take a few hours. You will get a timescale with the quote.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Leave it or put it right?
Running fresh sealant over the old joint is tempting, 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 Lullington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.
