About our window mastic in Marley
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on uPVC windows, aluminium frames and timber windows & doors, and common reasons people get in touch are draughts coming in around windows and doors and cracked or shrunken mastic around the frame.
In a village or hamlet like Marley, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job.

Common questions in Marley
Is Marley within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Marley for window mastic?
Yes. We work across London and the South East, and Marley is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you seal inside as well as outside?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
How we quote for window mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The size of the job
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Working hours on commercial sites
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
What we need to know
To make quoting easier, please include:
- Where the property is
- How we’d reach the joints
- The problem you’ve noticed
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames in most cases. In a small place like Marley, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Marley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Windows and doors in Marley
Historic houses like Leeds Castle (about 2.5 miles west) are a reminder that the area around Marley 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. 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.
For site and facilities teams at buildings such as Harrietsham Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Harrietsham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near St John the Baptist's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid harsh chemicals near the mastic
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
- Look round the frames every year or so
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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. Catching it early keeps the fix to a reseal.
