Window & door mastic in Kingston near Lewes, East Sussex
Window and door frames in Kingston near Lewes need attention? We remove the old material, prepare the joints and seal them properly.
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
About our window mastic in Kingston near Lewes
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. Common call-outs are for mastic that’s falling out in pieces and untidy mastic left by window fitters, across aluminium frames, patio & French doors and composite doors.
Homes in small places like Kingston near Lewes often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same 12-month guarantee.

The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. In a small place like Kingston near Lewes, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Housing providers, facilities teams and property managers book us too in Kingston near Lewes and across East Sussex. Several sites can go on one quote, and we are fully insured.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Kingston near Lewes, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why us?
- Colour agreed with you before any work starts
- A sealant colour to suit the surroundings

What else we do in Kingston near Lewes
How to look after the new joints
After the cure time, these simple habits help:
- Walk round the house once a year and look at the joints
- Clean frames with a soft cloth and soapy water
- Ventilate rooms so frames do not stay wet inside
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
How the job changes by surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Kingston near Lewes questions
Do you work for landlords with property near Lewes station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like Kingston near Lewes?
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.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you guarantee window mastic?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you match the sealant to my frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
When something else is needed
In fairness, some problems need a different trade:
- Worn gaskets, brush seals or a door that has dropped
- Soft or decayed wood in the frame
- A failed sealed unit that has misted up
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

What window mastic looks like in Kingston near Lewes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Anne of Cleves House (about 1.5 miles north-east) are a reminder that the area around Kingston near Lewes 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 let a flat or house near Lewes station, renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near St Pancras Church (Kingston near Lewes), replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Iford and Kingston Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
