Window mastic in Sevenscore
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, ring 0345 464 0079 or email us with the number of frames and any access details. We work on composite doors, window sills and aluminium frames, and people most often call us about mastic that has split away from the wall and white mastic on grey or black frames.
Mastic can only go onto a dry, clean joint, so window work in Sevenscore is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What happens on the day
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job generally takes most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. In a small place like Sevenscore, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Related advice
Keeping the joints in good condition
So the new joints stay in good condition:
- Look round the frames every year or so
- Wash the frames with mild soapy water
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Quotes for window mastic in Sevenscore
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Whether the work is at height
- How many areas need sealing
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
To make quoting easier, please include:
- How we’d reach the joints
- What’s wrong with the joints now
- Photos by email, if that’s easy
- Roughly how big the job is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- A sash or casement that will not close properly
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Common questions in Sevenscore
Does living near the coast affect window mastic in Sevenscore?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Sevenscore?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Different surfaces, different methods
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Frames and glazing around Sevenscore
Sevenscore is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Quex Park (about 2.8 miles north-west) nearby, there’s older building stock in the area around Sevenscore as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Thanet Parkway station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
