Window mastic in West Langdon from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Why deal with it now?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around West Langdon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Window mastic in West Langdon, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on uPVC windows, composite doors and window sills, and common reasons people get in touch are cracked or shrunken mastic around the frame and a bead that doesn’t match the frame.
Around West Langdon, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Wash the frames with mild soapy water
- Make sure the drainage slots aren’t blocked
- Avoid blasting the frames with a pressure washer
- Air rooms to keep condensation down around windows
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just phone 0345 464 0079 or send us an email.
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.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
The process
Most of a good job is in the 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 most of a day for a typical house, less for a few frames. Somewhere like West Langdon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Advice
When to call us in West Langdon
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
If you can see any of these, it’s time to have the joints looked at:
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
For site and facilities teams at buildings such as Langdon Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- How much experience the applicator has
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
- When the joint can take water or movement
Frames and glazing around West Langdon
Historic houses like Walmer Castle (about 3.9 miles north-east) are a reminder that the area around West Langdon 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Martin Mill station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.

What the job involves on each surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
