Window & door mastic in Swallows Cross, Essex
Our applicators work in Swallows Cross on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.

Window mastic for homes and businesses in Swallows Cross
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on window sills, patio & French doors and timber windows & doors, and common reasons people get in touch are draughts coming in around windows and doors and gaps where the sill meets the wall.
Mastic can only go onto a dry, clean joint, so window work in Swallows Cross is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Swallows Cross as everywhere else we work.

What affects the cost of window mastic
We quote each job individually. These are the things that affect it:
- How much there is to do
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- Access and height
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- Whether it has been sealed before
- The problem you’ve noticed
- The rough size of the job
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Surface by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
Composite doors
Front doors take the weather head on. We pay most attention there.

Swallows Cross questions
Is Swallows Cross in your area for window mastic?
Yes. We work across London and the South East, and Swallows Cross is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Ingatestone station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
How many windows can you do in a day?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.

Related advice
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When it is not the sealant
It helps to know what we can’t do too:
- Faulty window hardware
- A frame that has rotted at the joint
- Condensation trapped between the panes
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Swallows Cross homes and the weather
Historic houses like Ingatestone Hall (about 2.5 miles east) are a reminder that the area around Swallows Cross has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Shenfield High School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Ingatestone station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Do you need window mastic in Swallows Cross?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Any of these means the joints need attention:
- Cracked sealant at the sill ends
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
- Cold air getting in at the frame edge
Historic houses such as Ingatestone Hall, about 2.5 miles east, show how far back building around Swallows Cross goes, and older homes nearby need a sealant that suits their walls.
