What do you put in the joint?

Windows and doors in Lower Willingdon
Historic houses like Alfriston Clergy House (about 4 miles west) are a reminder that the area around Lower Willingdon has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Schools such as Willingdon Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Polegate station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Do you need window mastic in Lower Willingdon?
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
These are the problems we’re asked about most:
- Sealant in the wrong colour for the frame
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Leaking joints at the ends of sills
For an older house near a landmark such as St Wilfrid, the joint between an old wall and a newer frame is usually the first place rain gets in.

How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes most of a day for a typical house, less for a few frames. For a job in Lower Willingdon, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Clear items away from the joints we are working on

Related advice
Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a smaller place like Lower Willingdon, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How to look after the new joints
Aftercare is simple:
- Do not paint over the silicone
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
