Bromley Green homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Godinton House (about 4.5 miles north) are a reminder that the area around Bromley Green 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 Ham Street station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Historic houses such as Godinton House, about 4.5 miles north, show how far back building around Bromley Green goes, and older homes nearby need a sealant that suits their walls.

Window mastic in Bromley Green, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Typical jobs include white mastic on grey or black frames and cracked internal joints between frame and plaster, on composite doors, aluminium frames and uPVC windows.
Homes in small places like Bromley Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a one-year guarantee.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep timber frames painted
- Look round the frames every year or so
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
Most silicone sealants will not take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Bromley Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.

Different surfaces, different methods
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. Somewhere as small as Bromley Green, access is often the only tricky part. 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.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

Advice
How we quote for window mastic
You’ll get a clear quote before we start. It’s based on:
- How easy the joints are to reach
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- The address or postcode of the job
- Any previous sealing or DIY work
- What’s wrong with the joints now
- A few pictures by email, if you can
If you’re in Bromley Green and need window mastic, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Faulty window hardware
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Signs you need window mastic in Bromley Green
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The problems people normally mention when they call are:
- Cracked or shrunken mastic around the frame
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Cold air getting in at the frame edge
For site and facilities teams at buildings such as John Wallis Academy, larger buildings have plenty of frames, and the mastic around each one ages.
