Window Mastic in Staplecross
We cover Staplecross for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Damp patches on the reveal after heavy rain
- Whistling draughts around closed windows
- White mastic on grey or black frames
How we handle window mastic in Staplecross
Around Staplecross we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for draughty joints inside around the window and whistling draughts around closed windows, across patio & French doors, uPVC windows and aluminium frames.
Homes in small places like Staplecross often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Our work is backed for twelve months, in Staplecross and everywhere else we cover.

What we’re called out for in Staplecross
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
Homes close to St Marks Staplecross include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before you book
- Which sealant they’ll use, and why
- How long to leave it before use
- What happens if they find a problem under the old sealant
- Whether you can choose the colour
How we quote for window mastic
We don’t publish a price list. The quote depends on:
- Whether the work is at height
- The number and length of the joints
- Any mould that needs treating
- How many rooms, windows or areas are involved
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
What we need to know
To make quoting easier, let us know:
- Photos by email, if that is easy
- Whether it has been sealed before
- The rough size of the job
- What’s wrong with the joints now

What happens if it’s left?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Staplecross, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Windows and doors in Staplecross
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Durhamford Manor (about 2.4 miles south) are a reminder that the area around Staplecross 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.
Schools such as Staplecross Methodist Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Robertsbridge station, renewing tired window mastic between tenants heads off draught and damp complaints.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere as small as Staplecross, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep paint off silicone joints
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
