How we handle window mastic in Wickham Heath
Homes in Wickham Heath have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, aluminium frames and timber windows & doors, and people most often call us about gaps between the frame and the inside reveal and damp patches on the reveal after heavy rain.
In a village or hamlet like Wickham Heath, 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.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Why act early in Wickham Heath
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Wickham Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

What else we do in Wickham Heath
Wickham Heath homes and the weather
With historic houses such as Benham Park (about 1.8 miles south-east) nearby, there’s older building stock in the area around Wickham Heath 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 an older house near a landmark such as Parish Church of St Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Stockcross C.E. School? Then the mastic around its windows and doors needs looking after like any other building’s.

For rail, the closest station is Kintbury station, about 2.7 miles south-west of the centre.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Don’t use solvent cleaners on the joint
- Keep timber frames painted
- Check the mastic once a year
- Wipe condensation off the frames
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 call 0345 464 0079 or send us an email.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
How it works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job generally takes a morning for a couple of windows and a door. In a small place like Wickham Heath, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

Related advice
What we’re called out for in Wickham Heath
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Untidy mastic left by window fitters
- Whistling draughts around closed windows
- Gaps where the sill meets the wall
- Black, perished sealant on frames
Letting a property close to Kintbury station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Soft or decayed wood in the frame
- A sash or casement that won’t close properly
- Condensation trapped between the panes
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Composite doors
- uPVC windows
- Window sills
- Timber windows & doors
- Patio & French doors
- Aluminium frames
Different surfaces, different methods
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
Wickham Heath: your questions answered
I let a flat near Kintbury station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Is Wickham Heath within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages to suit the site.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
