About our window mastic in St Mary in the Marsh
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. Common call-outs are for white mastic on grey or black frames and old mastic that has gone black or come away, on window sills, timber windows & doors and patio & French doors.
Around St Mary in the Marsh, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Windows and doors in St Mary in the Marsh
St Mary in the Marsh is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Schools such as The Marsh Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. In a small place like St Mary in the Marsh, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Move anything stored near the joints

Common problems we fix in St Mary in the Marsh
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
If you can see any of these, it’s time to have the joints looked at:
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Mastic that is falling out in pieces
Homes close to Church of St Mary the Virgin include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What to look for in a quote
- When the joint can take water or movement
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Honest limits
To be straight with you, some problems need a different trade:
- Soft or decayed wood in the frame
- Broken hinges, locks or handles
- Condensation trapped between the panes
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Common questions in St Mary in the Marsh
Is St Mary in the Marsh within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do window mastic in St Mary in the Marsh?
Yes, St Mary in the Marsh is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Do you have insurance?
Yes. Full insurance covers our work.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like St Mary in the Marsh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.
