Window mastic in Barkham, done properly
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include draughty joints inside around the window and gaps left after new windows were fitted, across patio & French doors, uPVC windows and timber windows & doors.
Mastic can only go onto a dry, clean joint, so window work in Barkham is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Barkham homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Wokingham station, renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as The Coombes Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What we’re called out for in Barkham
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The most common problems we see are:
- Old mastic that has gone black or come away
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
In the older streets around Church of St James, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Are they insured?
- Is VAT in the price?
- How the surfaces are prepared before sealing
Barkham questions
Can you help a landlord with a rental near Wokingham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Barkham within the area you cover?
Yes, Barkham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Is the new sealant paintable?
Not normally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
Do you guarantee window mastic?
Yes. Every job comes with our 12-month guarantee, and we’re ARBOMaster approved applicators.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Older cottages and farmhouses around Barkham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Take a look at what affects the cost or our reviews.
Surface by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
What we can’t put right
We’ll always be straight with you, so here’s what sealant cannot fix:
- Damp problems in the wall away from the window
- A failed sealed unit that has misted up
- Broken hinges, locks or handles
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Where we work in Barkham

Work for landlords, hotels and businesses
Letting agents and landlords in Barkham can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we do, step by step
At the end, we look at the finished work together. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on how much there is to do. For a village or hamlet like Barkham, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Preparing for the visit
- Let us know about parking restrictions

We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- When we can work, for business premises
- The number and length of the joints
- The number of rooms or windows
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What we need to know
There’s no need for technical detail. Just tell us:
- How we’d reach the joints
- The type of property
- What’s wrong with the joints now
- Any previous sealing or DIY work
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.
