Window & door mastic in East Cholderton, Hampshire
Problem with your window and door frames in East Cholderton? We remove the old material, prepare the joints and seal them properly.
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
- Draughty joints inside around the window
How we handle window mastic in East Cholderton
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on composite doors, patio & French doors and timber windows & doors, and common reasons people get in touch are gaps between the frame and the inside reveal and gaps where the sill meets the wall.
Mastic can only go onto a dry, clean joint, so window work in East Cholderton is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our 12-month guarantee in East Cholderton and across Hampshire.

What we are called out for in East Cholderton
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
These are the problems we are asked about most:
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
For an older house near a landmark such as Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- Whether they’re fully insured
- Whether the sealant suits the joint
- Who turns up on the day
- What happens if the job turns out different

Questions from East Cholderton
Is East Cholderton in your area for window mastic?
Yes, East Cholderton is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Can you help a landlord with a rental near Grateley station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
When is the sealant fully cured?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Leave it or put it right?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around East Cholderton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
Why us?
- Any old sealant cut out fully, not covered over
- Full insurance on every job
- Neat joints and a tidy finish
- Every job guaranteed for a year

What window mastic looks like in East Cholderton
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Amport Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Grateley station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Wash the frames with mild soapy water
- Keep paint and stain on wooden frames in good order
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. Somewhere like East Cholderton needs a little journey planning: 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 look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

Different surfaces, different methods
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
Landlords, agents and businesses in East Cholderton
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
