Window mastic in Crowhurst, done properly
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 is why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include white mastic on grey or black frames and whistling draughts around closed windows, across timber windows & doors, window sills and composite doors.
Somewhere as small as Crowhurst, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What window mastic looks like in Crowhurst
With historic houses such as Durhamford Manor (about 3.8 miles north) nearby, there’s older building stock in the area around Crowhurst as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
Managing a site like Crowhurst CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to The Parish Church of St George include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. In a small place like Crowhurst, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.

What we are called out for in Crowhurst
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.
The problems people normally mention when they call include:
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
For landlords with property near Crowhurst station, renewing tired window mastic between tenants heads off draught and damp complaints.
