What window mastic looks like in Flishinghurst
With historic houses such as Scotney Castle (about 4.5 miles west) nearby, there’s older building stock in the area around Flishinghurst as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Colliers Green Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Marden station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Scotney Castle, about 4.5 miles west, is one of the historic houses in the wider area around Flishinghurst, and older homes nearby need a sealant that suits their walls.

What affects the quote in Flishinghurst
Jobs vary more than people expect. The main factors:
- Access and height
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Aftercare tips
To keep the joints looking good and working properly:
- Paint up to the joint, not over it
- Wipe condensation off the frames
- Check the mastic once a year
- Use gentle cleaners on frames and sealant
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Flishinghurst needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.

Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.

Yes. Just list everything you need and you will get one quote.

Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Places near Flishinghurst
What else we do in Flishinghurst
Surface by surface
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall and tooled smooth.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Flishinghurst, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
