Window & door mastic in Fair Cross, West Berkshire
We cover Fair Cross for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
How we handle window mastic in Fair Cross
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include draughts coming in around windows and doors and leaking joints at the ends of sills, on aluminium frames, uPVC windows and timber windows & doors.
Somewhere as small as Fair Cross, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door. Somewhere as small as Fair Cross, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Advice
What affects the cost of window mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Whether there’s mould to deal with
- The type of sealant required
- How many areas need sealing
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What we need to know
When you call or email, these details help:
- A few photos by email, if you can
- Whether it’s a home or a business
- Where the property is
- If someone has resealed it before
For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before work begins.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Do you need window mastic in Fair Cross?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
In the older streets around Church of St. Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- How much experience the applicator has
- Whether they’re fully insured
- Which colour the sealant will be
- What product goes in the joint
For landlords and businesses
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Faulty window hardware
- Rotten timber, which needs a joiner first
- Damp problems in the wall away from the window
If in doubt, call 0345 464 0079 or email us and we will say what we think.
What we seal
- Timber windows & doors
- Aluminium frames
- Patio & French doors
- Window sills
- Composite doors
- uPVC windows
Questions from Fair Cross
Can you do window mastic in Fair Cross?
Yes. Our work covers London and the South East, and Fair Cross is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Is Fair Cross within the area you cover?
Yes. Fair Cross is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Windows and doors in Fair Cross
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. Historic houses like Stratfield Saye House (about 0.7 miles south) are a reminder that the area around Fair Cross has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Mortimer station, renewing tired window mastic between tenants heads off draught and damp complaints.

Different surfaces, different methods
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
