DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic for homes and businesses in Appledore
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on window sills, timber windows & doors and composite doors, and people most often call us about hard, cracked sealant around windows and black, perished sealant on frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Appledore is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee.

Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
What do you need from me for a quote?

Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
How it works
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a morning for a couple of windows and a door, and we explain the cure time before we leave. For a village or hamlet like Appledore, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Appledore homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Smallhythe Place (about 3.9 miles west) nearby, there’s older building stock in the area around Appledore as well as newer homes. 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 Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
- Don’t aim a pressure washer at the joints
- Ventilate rooms so frames do not stay wet inside
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Faulty window hardware
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- uPVC windows
- Aluminium frames
- Patio & French doors
- Window sills
- Composite doors

Do you need window mastic in Appledore?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
People usually contact us when they notice one of these:
- Cracked internal joints between frame and plaster
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
- Mastic that’s falling out in pieces
Letting a property close to Appledore (Kent) station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Before booking anyone
- What guarantee comes with the work
- Are they insured?
- Who does the work, and how experienced they are
- When the joint can take water or movement
Different surfaces, different methods
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- How much there is to do
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
