Window mastic in Godinton
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on aluminium frames, patio & French doors and uPVC windows, and people most often call us about white mastic on grey or black frames and damp patches on the reveal after heavy rain.
Many houses in smaller places like Godinton have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. A visit to Godinton is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

- Tell us if parking is tricky

Windows and doors in Godinton
Historic houses like Godinton House (about 0.8 miles north-west) are a reminder that the area around Godinton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Godinton Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

When to call us in Godinton
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Any of these means the joints need attention:
- Black, perished sealant on frames
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
Letting a property close to Ashford International station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

- Which sealant they’ll use, and why

Why it’s worth doing now in Godinton
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around Godinton, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Do not aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
- Paint up to the joint, not over it
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

How long will my window job take?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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 fails, we can still redo it.
