Window mastic in Upper Hale
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We’re often asked to deal with water coming in at the bottom corners of a door and mastic that’s falling out in pieces, on uPVC windows, aluminium frames and window sills.
Houses in smaller places like Upper Hale can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Window mastic in Upper Hale: local notes
Historic houses like Farnham Castle (about 1.1 miles south) are a reminder that the area around Upper Hale 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Farnham station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to St Mark the Evangelist Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Hale School, larger buildings have plenty of frames, and the mastic around each one ages.

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. In a smaller place like Upper Hale, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look round the frames every year or so
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In a smaller place like Upper Hale, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- A failed sealed unit that has misted up
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals

Surface by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
