Common problems we fix in Quidhampton
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Any of these means the joints need attention:
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
Managing a site like Overton Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How we handle window mastic in Quidhampton
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on aluminium frames, patio & French doors and uPVC windows, and common reasons people get in touch are water coming in at the bottom corners of a door and draughty joints inside around the window.
Homes in small places like Quidhampton often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Wash the frames with mild soapy water
- Do not use solvent cleaners on the joint
- Don’t aim a pressure washer at the joints
- Make sure the drainage slots aren’t blocked
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
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.
Different surfaces, different methods
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Quidhampton homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Overton station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why it’s worth doing now in Quidhampton
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. Where a wall is exposed, as many are in small places like Quidhampton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

The process
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job generally takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Quidhampton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Mention if the joints have been sealed before
