Window mastic in Marsh Green
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for hard, cracked sealant around windows and mastic that’s falling out in pieces, across timber windows & doors, uPVC windows and patio & French doors.
In a village or hamlet like Marsh Green, 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.
There’s a 12-month guarantee on every job.

Looking after it afterwards
After the cure time, these simple habits help:
- Avoid harsh chemicals near the mastic
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Walk round the house once a year and look at the joints
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or email us.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Why it’s worth doing now in Marsh Green
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Marsh Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Your questions about window mastic in Marsh Green
Is Marsh Green within the area you cover?
Yes. Marsh Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is window mastic in a coastal place like Marsh Green any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Do you have sealant for grey or black windows?
Yes, in most cases. Tell us the frame colour when you get in touch and we will match it as closely as we can.
How long will my window job take?
A few frames take a few hours. We confirm the timing with your quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.

We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.

What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It generally takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Marsh Green, the journey is planned in advance: 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.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.

- Every joint is tooled smooth and checked before we leave.

What window mastic looks like in Marsh Green
Marsh Green is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. 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.
Managing a site like Brighstone Church of England Aided Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St. Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
