About our window mastic in Lower Cadsden
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have draughty joints inside around the window and hard, cracked sealant around windows, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Lower Cadsden is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Other services in Lower Cadsden
Different surfaces, different methods
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
What we’re called out for in Lower Cadsden
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Common reasons people contact us are:
- Rain getting in at the frame or under the sill
- Leaking joints at the ends of sills
- Draughty joints inside around the window
- Gaps left after new windows were fitted
If you look after a building such as Monks Risborough CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Which sealant they’ll use, and why
- Whether they’re fully insured
- Is the old sealant removed completely?
- How long to leave it before use
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. In a small place like Lower Cadsden, access is usually 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.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Advice
Windows and doors in Lower Cadsden
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Monks Risborough station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in Lower Cadsden
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Lower Cadsden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
