Window mastic for homes and businesses in The Mint
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Typical jobs include cracked internal joints between frame and plaster and mastic that’s falling out in pieces, across aluminium frames, window sills and composite doors.
Mastic can only go onto a dry, clean joint, so window work in The Mint is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same one-year guarantee.

Do you need window mastic in The Mint?
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
For site and facilities teams at buildings such as Liss Junior School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- What product goes in the joint
- What happens if the job turns out different
- Who turns up on the day
- What insurance they hold
Leave it or put it right?
The work is quick compared with the damage it prevents: the visit 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. In a small place like The Mint, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
Common questions in The Mint
Is The Mint within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Liss station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
How long will my window job take?
The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
- A sash or casement that won’t close properly
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
Surfaces we seal
- Timber windows & doors
- Composite doors
- Window sills
- uPVC windows
- Patio & French doors
- Aluminium frames
Frames and glazing around The Mint
Rainfall in the South East is lower than in much 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 Hope Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Liss station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It usually takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like The Mint, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
