Window mastic for homes and businesses in Molash
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on patio & French doors, uPVC windows and aluminium frames, and the jobs we see most are cracked or shrunken mastic around the frame and white mastic on grey or black frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Molash is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. In a small place like Molash, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- 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.
- Every joint is checked before we leave.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

It depends on the product. Some smell for a while, some hardly at all.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Frames and glazing around Molash
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 Belmont House and Gardens (about 3.8 miles north-west) nearby, there’s older building stock in the area around Molash as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Church of St Peter include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Wye station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Surface by 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.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Clean frames with a soft cloth and soapy water
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
- Check the mastic once a year
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around Molash, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- The size of the job
- Mould in or behind the old joints
- The product the joint needs
- How much old sealant there is and how hard it is to remove
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- How we’d reach the joints
- If someone has resealed it before
