Window mastic across Broyle Side and nearby, with every bit of old sealant taken out first.
- Black, perished sealant on frames
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
What the job involves on each surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for property managers and facilities teams in Broyle Side and across East Sussex. Several sites can be quoted together, and we are fully insured for the work.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Common problems we fix in Broyle Side
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
Keep an eye out for any of the following:
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
Letting a property close to Glynde station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the visit works
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. Most jobs take a morning for a couple of windows and a door. In a small place like Broyle Side, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on

Do you cover Broyle Side for window mastic?
Yes, Broyle Side is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or drop us an email.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Where are you based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
- A sash or casement that won’t close properly
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Frames and glazing around Broyle Side
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Glyndebourne (about 1.7 miles south) are a reminder that the area around Broyle Side has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as The Parish Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Ringmer Community College and Sixth Form? Then larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Clean frames with a soft cloth and soapy water
- Repaint timber before it’s bare
- Keep paint off silicone joints
- Check the mastic once a year
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
