What happens if it’s left?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Padbury, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

- We leave the area clean and tidy
- We’re fully insured

Window mastic in Padbury
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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on patio & French doors, uPVC windows and timber windows & doors, and people most often call us about black, perished sealant on frames and mastic that has split away from the wall.
Around Padbury, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All our work is covered by a 12-month guarantee, wherever you are in Buckinghamshire.

What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- Access and height
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
Photos help, but a description is a good start. Please mention:
- Where the property is
- Whether it has been sealed before
- The problem you’ve noticed
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Frames and glazing around Padbury
With historic houses such as Claydon House (about 3.3 miles south) nearby, there’s older building stock in the area around Padbury as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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 Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Common problems we fix in Padbury
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Hard, cracked sealant around windows
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
If you look after a building such as Padbury Church of England School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- Whether VAT is included
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep drainage slots and sill grooves clear
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Padbury needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

Related advice
Can I do it myself?
Too much sealant is as bad as too little. 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. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
