Different surfaces, different methods
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What happens if it’s left?
Choosing the product is half the job. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In an older home around Brompton, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

What affects the quote in Brompton
For a quick quote, just ask. What matters most is:
- The old material and how stubborn it is
- Whether the work is at height
- The size of the job
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- If someone has resealed it before

FAQs for Brompton
Do you work for landlords with property near Chatham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is window mastic in a coastal place like Brompton any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Will new mastic stop draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can new window sealant be painted?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
Frames and glazing around Brompton
Brompton is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Chatham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Brompton-Westbrook Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works

It normally takes a morning for a couple of windows and a door. In a smaller place like Brompton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Clear the area around the work

Related advice
Do you need window mastic in Brompton?
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for these signs:
- White mastic on grey or black frames
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- Rain getting in at the frame or under the sill
If you live in an older home near Brompton Garrison Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
