When to call us in Steventon End
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.
Any of these means the joints need attention:
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Sealant in the wrong colour for the frame
- Old mastic that has gone black or come away
For site and facilities teams at buildings such as Ashdon Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Landlords, agents and businesses in Steventon End
Landlords and letting agents in Steventon End can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Ventilate rooms so frames don’t stay wet inside
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Don’t paint over the silicone
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Why it’s worth doing now in Steventon End
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 soon lifts and the leak carries on behind it. The old mastic has to come out. Older cottages and farmhouses around Steventon End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Why book with us
- A sealant colour to suit the surroundings
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
- Any old sealant cut out fully, not covered over
The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Steventon End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
