Questions from Lower Green
Do you cover smaller places like Lower Green?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is window mastic in Lower Green guaranteed?
All our work, in Lower Green and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.
Can I paint over the new sealant?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
About our window mastic in Lower Green
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on window sills, composite doors and timber windows & doors, and common reasons people get in touch are water coming in at the bottom corners of a door and rushed sealant from a window installation.
Somewhere as small as Lower Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All our work is covered by a one-year guarantee.

Surface by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Landlords, agents and businesses in Lower Green
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Letting agents and landlords in Lower Green can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Windows and doors in Lower Green
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.
If you live in an older home near Church of St John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Asking for a quote
Before you ask for a quote, have a think about:
- Photos by email, if that is easy
- The type of property
- Whether it has been sealed before
- Roughly how big the job is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
When to call us in Lower Green
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
People usually contact us when they notice one of these:
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
Around Lower Green, as everywhere, window mastic is only as good as the preparation behind it.

- Whether all the old sealant comes out first
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are in most cases. In a small place like Lower Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Clear the area around the work
