About our window mastic in Braishfield
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Typical jobs include cracked internal joints between frame and plaster and whistling draughts around closed windows, across window sills, uPVC windows and aluminium frames.
Mastic can only go onto a dry, clean joint, so window work in Braishfield 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 there’s a problem with our work within the year, let us know and we will sort it.

Different surfaces, different methods
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.

What else we do in Braishfield
Why act early in Braishfield
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Where a wall is exposed, as many are in small places like Braishfield, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Windows and doors in Braishfield
With historic houses such as Mottisfont Abbey (about 3.3 miles north-west) nearby, there’s older building stock in the area around Braishfield as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Romsey station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Braishfield Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
When to call us in Braishfield
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Draughty joints inside around the window
- Black, perished sealant on frames
- A bead that does not match the frame
- Damp patches on the reveal after heavy rain
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Who turns up on the day
- What the cure time is
- Is the old sealant removed completely?
- Are they insured?
