About our window mastic in Drayton Beauchamp
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. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, patio & French doors and timber windows & doors, and common reasons people get in touch are gaps between the frame and the inside reveal and rushed sealant from a window installation.
Outdoor sealant needs dry, clean surfaces, so work on frames around Drayton Beauchamp is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Drayton Beauchamp, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Aftercare tips
After the cure time, these simple habits help:
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Paint up to the joint, not over it
- Make sure the drainage slots are not blocked
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
What happens if it’s left?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Older cottages and farmhouses around Drayton Beauchamp can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What affects the cost of window mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- The product the joint needs
- The number and length of the joints
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Photos by email, if that is easy
- If someone has resealed it before
- Any access issues, like height or stairs
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Questions from Drayton Beauchamp
I let a flat near Tring station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Drayton Beauchamp?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly.
Where is Mr Mastic based?

Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Can you reach windows above the ground floor?
Usually, yes. Access is planned before any work starts, so mention the height and anything in the way.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you need window mastic in Drayton Beauchamp?
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
It’s worth asking for a quote if you see:
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
For site and facilities teams at buildings such as Goldfield Infants' and Nursery School, the mastic around its windows and doors needs looking after like any other building’s.

What window mastic looks like in Drayton Beauchamp
London and the South East are among 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 Cholesbury Manor House (about 3.6 miles south-east) are a reminder that the area around Drayton Beauchamp 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.
In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Tring station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
