How the job changes by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
Common questions in Willows Green
Will you come out to Willows Green?
Yes, Willows Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Braintree station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
How many windows can you do in a day?
A handful of frames is a short visit, while a whole house takes longer. You will get a timescale with the quote.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. Somewhere as small as Willows Green, 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.
- Every joint is checked before we leave.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Older cottages and farmhouses around Willows Green can have timber 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 work begins, so you know where you stand.
What you get with us
- Colour agreed with you before we start
- Sanitary silicone with an anti-fungal additive in wet areas
- Neat joints and a tidy finish
- Colour picked to suit the job
Keeping the joints in good condition
So the new joints stay in good condition:
- Don’t paint over the silicone
- Keep paint and stain on wooden frames in good order
- Keep jet washers away from the mastic
- Clean frames with a soft cloth and soapy water
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
What sealant work cannot fix
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- A frame that has rotted at the joint
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on
