Mastic around window and door frames, sills and patio doors for homes and businesses in Connaught Village and across Greater London. Fully insured, ARBOMaster approved and guaranteed for a year.

Window mastic in Connaught Village, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Typical jobs include cracked or shrunken mastic around the frame and whistling draughts around closed windows, on window sills, timber windows & doors and composite doors.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Surface by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
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.

Window mastic in Connaught Village: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Hampden Gurney CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St John the Evangelist include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
- Wipe condensation off the frames
- Keep timber frames painted
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
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.
FAQs for Connaught Village
Is parking a problem for a job in Connaught Village?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you help a landlord with a rental near London Paddington station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
How many windows can you do in a day?
The work takes a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you come to Connaught Village?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Connaught Village.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.

Leave it or put it right?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a flat in Connaught Village, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
The process
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. In a London area like Connaught Village, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- 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.
Before we arrive
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before

Advice
When to call us in Connaught Village
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Cracked sealant at the sill ends
Connaught Village is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
