What happens on the day
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Bramshill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in

Window mastic for homes and businesses in Bramshill
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. We work on aluminium frames, uPVC windows and timber windows & doors, and people most often call us about draughts coming in around windows and doors and cracked internal joints between frame and plaster.
Around Bramshill, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
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.

Signs you need window mastic in Bramshill
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
The problems people generally mention when they call include:
- Old mastic that has gone black or come away
- Mastic that has split away from the wall
- Whistling draughts around closed windows
- Leaking joints at the ends of sills
Letting a property close to Winchfield station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- Are they insured?
- How much experience the applicator has
- What guarantee comes with the work
- What product goes in the joint
Window mastic in Bramshill: local notes
Historic houses like Stratfield Saye House (about 2.8 miles west) are a reminder that the area around Bramshill 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Mission Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Make sure the drainage slots are not blocked
- Don’t aim a pressure washer at the joints
- Avoid harsh chemicals near the mastic
- Paint up to the joint, not over it
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Bramshill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
