Window Mastic in Warren Street

- White mastic on grey or black frames
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. In a small place like Warren Street, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

About our window mastic in Warren Street
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. We work on uPVC windows, timber windows & doors and window sills, and common reasons people get in touch are hard, cracked sealant around windows and old mastic that has gone black or come away.
Somewhere as small as Warren Street, 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.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Looking after it afterwards
To keep the joints looking good and working properly:
- Do not use solvent cleaners on the joint
- Look round the frames every year or so
- Keep paint and stain on wooden frames in good order
- Wipe condensation off the frames
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
What window mastic looks like in Warren Street
The South East is one of 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 Belmont House and Gardens (about 4.1 miles north-east) are a reminder that the area around Warren Street 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.
Managing a site like The Lenham School? Then the mastic around its windows and doors needs looking after like any other building’s. Historic houses such as Belmont House and Gardens, about 4.1 miles north-east, show how far back building around Warren Street goes, and older homes nearby need a sealant that suits their walls.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Warren Street: your questions answered
I let a flat near Lenham station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover Warren Street for window mastic?
Yes. Our work covers London and the South East, and Warren Street is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Is it worth trying it myself?
That depends on the joint. 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.
How long will my window job take?
A handful of frames is a short visit, while a whole house takes longer. You’ll get a timescale with the quote.
Do you need window mastic in Warren Street?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
People normally contact us after spotting one of these:
- Water coming in at the bottom corners of a door
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
If you let a flat or house near Lenham station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- How hidden problems are handled
- What product goes in the joint
- Is VAT in the price?
- When the joint can take water or movement
Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall and tooled smooth.
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.
