How we handle window mastic in Upper Enham
A window frame and the wall around it expand and shrink at different rates. 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. We work on timber windows & doors, aluminium frames and uPVC windows, and the jobs we see most are draughty joints inside around the window and a bead that doesn’t match the frame.
Mastic can only go onto a dry, clean joint, so window work in Upper Enham is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with a 12-month guarantee.

What else we do in Upper Enham
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames in most cases. Somewhere like Upper Enham needs a little journey planning: 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 confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
How to prepare
- Mention any parking rules near the property
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises
Ask for a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
Advice
Honest limits
It helps to know what we cannot do too:
- Worn gaskets, brush seals or a door that has dropped
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly.

Why act early in Upper Enham
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Upper Enham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear quote before any work starts.

Different surfaces, different methods
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 look for the cause first.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.

Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Upper Enham, along with the rest of our area.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clean frames with a soft cloth and soapy water
- Keep paint off silicone joints
- Walk round the house once a year and look at the joints
- Do not aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
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.
Frames and glazing around Upper Enham
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Andover station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Saint George, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Smannell and Enham Church of England (Aided) Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
