About our window mastic in Stone
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you’re dealing with a bead that doesn’t match the frame and mastic that’s falling out in pieces, we can help.
Homes in small places like Stone often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee.

When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- A sash or casement that will not close properly
- A frame that has rotted at the joint
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
What we seal
- Patio & French doors
- Aluminium frames
- uPVC windows
- Composite doors
- Window sills
- Timber windows & doors

Windows and doors in Stone
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Waddesdon Manor (about 4.1 miles north-west) are a reminder that the area around Stone 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 is traditional sand mastic.
Letting a property close to Aylesbury Vale Parkway station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Stone is about 2 miles south-west of Aylesbury, in Buckinghamshire. Wherever you are in the HP17 postcode area, our applicators can take on window mastic. Our Buckinghamshire coverage runs to 263 places, and Stone is one of them. Our Oxford page covers work nearby (16 miles or so).
We cover every part of the HP17 postcode area for window mastic. You will find streets such as Church Way, Raven Forge and Badgers Rise. We also cover the places around Stone: Hartwell (1 mile east), Fairford Leys (1 mile north-east), Haydon Hill (2 miles north-east), Fleet Marston (2 miles north) and Southcourt (2 miles east).

Landmarks near Stone
Locally, jobs take us to homes and businesses close to Sir Henry Floyd Grammar School and The Rose & Crown pub, among other places. For rail, the closest station is Aylesbury Vale Parkway station, roughly 1.9 miles north. Other landmarks nearby include Roald Dahl Children's Gallery (2.3 miles north-east) and Dinton Castle (1.2 miles west). For a walk, there’s Beacon Hill and Snakemoor.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Aftercare tips
To keep the joints looking good and working properly:
- Walk round the house once a year and look at the joints
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
- Repaint timber before it’s bare
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Stone needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Advice
Surface by surface
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Questions from Stone
Will you come out to Stone?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Stone in your area for window mastic?
Yes, Stone is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do you guarantee window mastic?
Yes. Every job comes with our 12-month guarantee, and we’re fully insured.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a small place like Stone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.

Do you need window mastic in Stone?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
These are the problems we are asked about most:
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
Managing a site like Stone Church of England Combined School? Then larger buildings have plenty of frames, and the mastic around each one ages.
