About our window mastic in Lions Green
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on uPVC windows, aluminium frames and patio & French doors, and common reasons people get in touch are gaps where the sill meets the wall and draughts coming in around windows and doors.
Around Lions Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Common questions in Lions Green
Is window mastic in Lions Green guaranteed?
All our work, in Lions Green and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Lions Green within the area you cover?
Yes, Lions Green is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How much does window mastic cost in Lions Green?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Do you work for letting agents?
Yes, often. Several properties can be quoted together.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Lions Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
What you get with us
- Old sealant always removed completely
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
- Experience in homes, commercial sites and hotels

What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Lions Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Advice
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Look round the frames every year or so
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Keep timber frames painted
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
What affects the cost of window mastic
The quote reflects the job in front of us. We take into account:
- The old material and how stubborn it is
- How many areas need sealing
- Whether there’s mould to deal with
- How easy the joints are to reach
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Whether it has been sealed before
For a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
When something else is needed
A few problems are outside what sealant work can do:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
- Faulty window hardware
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

What window mastic looks like in Lions Green
With historic houses such as Horselunges Manor (about 4 miles south) nearby, there’s older building stock in the area around Lions Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Lions Green, as anywhere, good window mastic starts with a clean, dry, properly prepared joint. Homes close to The Parish Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What the job involves on each surface
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
