Hawkley homes and the weather
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.
For an older house near a landmark such as Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a small place like Hawkley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Walk round the house once a year and look at the joints
- Keep paint off silicone joints
- Do not use solvent cleaners on the joint
- Ventilate rooms so frames don’t stay wet inside
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What we’re called out for in Hawkley
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Most people get in touch after spotting something like this:
- Old mastic that has gone black or come away
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
For landlords with property near Liss station, renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- How the surfaces are prepared before sealing
- Who turns up on the day
- Which colour the sealant will be
- What product goes in the joint
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work usually takes most of a day for a typical house, less for a few frames. Somewhere as small as Hawkley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
