How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Hadlow Down, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

About our window mastic in Hadlow Down
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you’re dealing with gaps between the frame and the inside reveal and black, perished sealant on frames, we can put it right, on aluminium frames, timber windows & doors and patio & French doors alike.
Mastic can only go onto a dry, clean joint, so window work in Hadlow Down is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What affects the cost of window mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether the work is at height
- Any mould that needs treating
- Working hours on commercial sites
- The amount of work
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Any previous sealing or DIY work
- The address or postcode of the job
- The rough size of the job
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.
Common problems we fix in Hadlow Down
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
- Gaps between the frame and the inside reveal
- Cold air getting in at the frame edge
If you live in an older home near St Mark's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
- Don’t use solvent cleaners on the joint
- Do not paint over the silicone
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Hadlow Down questions
Do you cover Hadlow Down for window mastic?
Yes, Hadlow Down is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Will you come out to Hadlow Down?
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 seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
How long will my window job take?
A few frames take a few hours, while a whole house takes longer. You will get a timescale with the quote.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Hadlow Down, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Hadlow Down homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Buxted station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as St Mark's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
