Window mastic for homes and businesses in Broad Oak
Around Broad Oak we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with cold air getting in at the frame edge and water coming in at the bottom corners of a door, we can put it right, whatever the surface.
In a village or hamlet like Broad Oak, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Whatever the size of the job, it’s backed by our one-year guarantee in Broad Oak and across East Sussex.

Why act early in Broad Oak
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Broad Oak can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
Why book with us
- Tidy, careful work
- Domestic, commercial and hotel work
- Quality sealants from Arbo and Everbuild
- Any old sealant cut out fully, not covered over

What the job involves on each surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as that is a job for a joiner.
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a morning for a couple of windows and a door. In a small place like Broad Oak, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
How to get a quote

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots aren’t blocked
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Signs you need window mastic in Broad Oak
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
These are the problems we are asked about most:
- Gaps where the sill meets the wall
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
If you live in an older home near The Parish Church of St George, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before booking

What window mastic looks like in Broad Oak
With historic houses such as Great Dixter (about 3.3 miles north) nearby, there’s older building stock in the area around Broad Oak as well as newer homes. In older buildings, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Doleham station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Brede Primary School, the mastic around its windows and doors needs looking after like any other building’s.
