Signs you need window mastic in Lanham Green
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Signs it’s time to call us include:
- Damp patches on the reveal after heavy rain
- A bead that doesn’t match the frame
- Gaps between the frame and the inside reveal
- Cold air getting in at the frame edge
Rented homes near Cressing station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic in Lanham Green, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on aluminium frames, timber windows & doors and composite doors, and people most often call us about rushed sealant from a window installation and cracked sealant at the sill ends.
Mastic can only go onto a dry, clean joint, so window work in Lanham Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why it’s worth doing now in Lanham Green
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 Lanham Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Don’t aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
- Ventilate rooms so frames do not stay wet inside
- Keep timber frames painted
Most silicone sealants will not take paint, so mention any painting plans before we start. We can use a paintable sealant where that matters.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

Advice
Surface by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
Lanham Green homes and the weather
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 site and facilities teams at buildings such as Cressing Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Parish Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
