Window mastic for homes and businesses in Beamond End
Around Beamond End we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for mastic that’s falling out in pieces and cracked internal joints between frame and plaster, on window sills, composite doors and patio & French doors.
In a village or hamlet like Beamond End, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What affects the cost of window mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- Which sealant suits the joint
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Where the property is
- Whether it has been sealed before
- The rough size of the job
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.

When to call us in Beamond End
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Keep an eye out for any of the following:
- Leaking joints at the ends of sills
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
- Black, perished sealant on frames
For landlords with property near Great Missenden station, renewing tired window mastic between tenants heads off draught and damp complaints.

The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a morning for a couple of windows and a door. Somewhere as small as Beamond End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children

Windows and doors in Beamond End
Historic houses like Hughenden Manor (about 3.5 miles west) are a reminder that the area around Beamond End 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Holmer Green Junior School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
How to look after the new joints
So the new joints stay in good condition:
- Do not use solvent cleaners on the joint
- Avoid blasting the frames with a pressure washer
- Keep paint and stain on wooden frames in good order
- Walk round the house once a year and look at the joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
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.
Surface by surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
