Window mastic in Littlebourne, done properly

Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. We work on timber windows & doors, composite doors and uPVC windows, and people most often call us about gaps between the frame and the inside reveal and black, perished sealant on frames.
Mastic can only go onto a dry, clean joint, so window work in Littlebourne is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, it’s backed by our one-year guarantee in Littlebourne and across Kent.

The process
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a morning for a couple of windows and a door, and we explain the cure time before we leave. Somewhere as small as Littlebourne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- 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.
Before we arrive
- Clear the area around the work
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Advice
What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Littlebourne can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Littlebourne: your questions answered
Will you come out to Littlebourne?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do window mastic in Littlebourne?
Yes, Littlebourne is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
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.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
Can you do upstairs windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
When is the sealant fully cured?
It depends on the product. Before we leave, we’ll tell you the cure time.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can I do it myself?
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.
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, and the work is guaranteed for a year.
Frames and glazing around Littlebourne
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Goodnestone Park (about 3.5 miles south-east) are a reminder that the area around Littlebourne has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Vincent, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Littlebourne Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Landlords and agents in Littlebourne can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Signs you need window mastic in Littlebourne
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 generally contact us after spotting one of these:
- Black, perished sealant on frames
- White mastic on grey or black frames
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
For landlords with property near Bekesbourne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Which colour the sealant will be
- Is VAT in the price?
- How much experience the applicator has
- How the surfaces are prepared before sealing
Keeping the joints in good condition
So the new joints stay in good condition:
- Wash the frames with mild soapy water
- Keep paint off silicone joints
- Do not use solvent cleaners on the joint
- Ventilate rooms so frames don’t stay wet inside
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
