FAQs for Clanville
Will you come out to Clanville?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Clanville for window mastic?
Yes, Clanville is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
About our window mastic in Clanville
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before we start. To get one, ring 0345 464 0079 or send us an email with the number of frames and any access details. Typical jobs include cracked internal joints between frame and plaster and rain getting in at the frame or under the sill, across patio & French doors, window sills and timber windows & doors.
In a village or hamlet like Clanville, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Do you need window mastic in Clanville?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
People generally contact us when they notice one of these:
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- White mastic on grey or black frames
For landlords with property near Andover station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
What sealant work cannot fix
We won’t take on work that will not last, so these are the limits:
- Faulty window hardware
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Timber windows & doors
- Composite doors
- Patio & French doors
- uPVC windows
- Aluminium frames
- Window sills
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. For a village or hamlet like Clanville, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
- Keep children and pets away from the work area

What else we do in Clanville
Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a small place like Clanville, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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, so you know where you stand.

Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Frames and glazing around Clanville
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 an older house near a landmark such as St Margaret's Chapel, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Appleshaw St Peter's CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
