Window mastic in Woolmer
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with a bead that doesn’t match the frame and gaps where the sill meets the wall, we can put it right, on aluminium frames, composite doors and uPVC windows alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Woolmer is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Common questions in Woolmer
Do you work for landlords with property near Liss station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Woolmer?
Yes. Woolmer is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I paint over the new sealant?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months, inside or out.
How do I get a quote for window mastic in Woolmer?
Size, access and the old material all affect the cost. Ask us for a quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
What window mastic looks like in Woolmer
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St Matthew's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Liss station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as St Matthew's Church of England Aided Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. For a village or hamlet like Woolmer, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access
- On commercial sites, let us know about site rules

Advice
Looking after it afterwards
After the cure time, these simple habits help:
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
- Use gentle cleaners on frames and sealant
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Why deal with it now?
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. Where a wall is exposed, as many are in small places like Woolmer, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
