Window & door mastic in Hickstead, West Sussex
Our applicators work in Hickstead on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
- Sealant in the wrong colour for the frame
Honest limits
We’ll always be straight with you, so here’s what new sealant will not do:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint

About our window mastic in Hickstead
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We are often asked to deal with gaps where the sill meets the wall and hard, cracked sealant around windows, on window sills, composite doors and uPVC windows.
Homes in small places like Hickstead often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Frames and glazing around Hickstead
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ockenden Manor (about 3.4 miles north-east) are a reminder that the area around Hickstead has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Burgess Hill station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around The Parish Church of St Peter, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Twineham CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a small place like Hickstead, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: 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 will explain what it covers.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Hickstead, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Tell us about any water getting in

Advice
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid harsh chemicals near the mastic
- Make sure the drainage slots aren’t blocked
- Do not paint over the silicone
- Walk round the house once a year and look at the joints
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
