Surface by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Window mastic for homes and businesses in Snagshall
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include cracked sealant at the sill ends and gaps between the frame and the inside reveal, on aluminium frames, window sills and patio & French doors.
Somewhere as small as Snagshall, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to a full day, depending on how many frames there are.

Everything for the job comes with us, so a second trip is avoided where possible.
- 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.

Do you seal inside as well as outside?

What does window mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Snagshall, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What sealant work can’t fix
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Patio & French doors
- Window sills
- Composite doors

Snagshall homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Great Dixter (about 2.2 miles east) are a reminder that the area around Snagshall has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Bodiam Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Robertsbridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to The Parish Church of St James include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Should I try it myself first?
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
