About our window mastic in Furzton
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with black, perished sealant on frames and draughty joints inside around the window, on uPVC windows, composite doors and patio & French doors.
In smaller places like Furzton, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Your job is guaranteed for a year, as with all our work.

Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

What else we do in Furzton
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door from start to finish. Parking around Furzton is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Before we arrive
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on

Related advice
Keeping the joints in good condition
After the cure time, these simple habits help:
- Ventilate rooms so frames don’t stay wet inside
- Use gentle cleaners on frames and sealant
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Why act early in Furzton
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. In an older home around Furzton, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Frames and glazing around Furzton
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Bletchley Park (about 1.1 miles south-east) are a reminder that the area around Furzton has older buildings as well as new. 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.
Rented homes near Bletchley station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Barleyhurst Park Primary are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of the Servant King, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
