Window Mastic in Nyetimber
Problem with your window and door frames in Nyetimber? We cut out the old, prepare the joints and apply the right sealant.
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
Window mastic in Nyetimber
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on uPVC windows, window sills and composite doors, and people most often call us about cold air getting in at the frame edge and gaps between the frame and the inside reveal.
Around Nyetimber, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
A little care helps the new joints last. Our advice:
- Paint up to the joint, not over it
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
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.

Are you fully insured?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Do you need window mastic in Nyetimber?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Most people get in touch when they notice one of these:
- A bead that doesn’t match the frame
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
If you let a flat or house near Bognor Regis station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Leave it or put it right?
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. A reseal is a much smaller job. In a smaller place like Nyetimber, 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.

What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a few frames, or a day or more for a whole house. For a job in Nyetimber, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

Window mastic in Nyetimber: local notes
Nyetimber is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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.
In the older streets around The Parish Church of St Thomas A Becket, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Rose Green Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
