Window & door mastic in Lydden, Kent
Window and door frames in Lydden need attention? We remove the old material, prepare the joints and seal them properly.
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
- Cracked or shrunken mastic around the frame
About our window mastic in Lydden
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have mastic that has split away from the wall and white mastic on grey or black frames, we can put it right, whatever the surface.
Somewhere as small as Lydden, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work comes with our 12-month guarantee, wherever you are in Kent.

How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- Any mould that needs treating
- Access and height
- The number and length of the joints
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- What’s wrong with the joints now
We quote each job on its own. Simply phone 0345 464 0079 or send us an email and describe the job, and pictures are welcome.

Surface by surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Why act early in Lydden
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Lydden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- Arbo and Everbuild products
- We never seal over old sealant
- We are fully insured

Your questions about window mastic in Lydden
Do you cover smaller places like Lydden?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Kearsney station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you seal inside as well as outside?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Can you do upstairs windows?
Normally, yes. Access is planned before we start.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What window mastic looks like in Lydden
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary Church of St Mary Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Kearsney station, renewing tired window mastic between tenants heads off draught and damp complaints.

What’s near Lydden

What we are called out for in Lydden
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.
Signs it’s time to call us include:
- Black, perished sealant on frames
- A bead that doesn’t match the frame
- Leaking joints at the ends of sills
- Rushed sealant from a window installation
If you look after a building such as Lydden Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- When the joint can take water or movement
- Whether all the old sealant comes out first
- Is VAT in the price?
- Who does the work, and how experienced they are
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. In a small place like Lydden, access is usually 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.
- Deep gaps get closed-cell backing rod to set the depth.

- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
