Window mastic in Howlett End, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. Common call-outs are for old mastic that has gone black or come away and cracked sealant at the sill ends, across aluminium frames, window sills and composite doors.
Somewhere as small as Howlett End, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our 12-month guarantee.

Is Howlett End in your area for window mastic?

Do you have insurance?

Does the work come with a guarantee?

Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you work on first-floor windows?
Yes, in most cases. Access is planned before work begins, so mention the height and anything in the way.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How the job changes by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.

When to call us in Howlett End
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The most common problems we see are:
- A bead that does not match the frame
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
If you live in an older home near St Paul's Mission Room, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Howlett End
The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Howlett End, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Frames and glazing around Howlett End
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Horham Hall (about 3.2 miles south) are a reminder that the area around Howlett End has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you let a flat or house near Newport (Essex) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Wimbish Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Ventilate rooms so frames do not stay wet inside
- Do not paint over the silicone
- Keep drainage slots and sill grooves clear
- Keep timber frames painted
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. For a village or hamlet like Howlett End, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Mention any parking rules near the property
