About our window mastic in Four Ashes
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you have white mastic on grey or black frames and gaps between the frame and the inside reveal, we can put it right, on timber windows & doors, window sills and uPVC windows alike.
Homes in small places like Four Ashes often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a one-year guarantee.

The process
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take most of a day for a typical house, less for a few frames. For a village or hamlet like Four Ashes, the journey is planned in advance: 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 look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Work for landlords, hotels and businesses
For anyone letting property in or around Four Ashes, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep drainage slots and sill grooves clear
- Keep paint off silicone joints
- Wash the frames with mild soapy water
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Common questions in Four Ashes
Can you help a landlord with a rental near High Wycombe 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.
Will you come out to Four Ashes?
Yes. Four Ashes is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
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.

Frames and glazing around Four Ashes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hughenden Manor (about 1 mile west) are a reminder that the area around Four Ashes has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to St Michael and All Angels Church include some older properties, and 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 High Wycombe station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like Great Kingshill Church of England Combined School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Photos by email are helpful but not essential. Please mention:

What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- A failed sealed unit that has misted up
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
What we seal
- Timber windows & doors
- uPVC windows
- Composite doors
- Aluminium frames

How the job changes by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
