About our window mastic in Stubb's Cross
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on aluminium frames, composite doors and window sills, and people most often call us about black, perished sealant on frames and draughts coming in around windows and doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around Stubb's Cross is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, large or small.

Frames and glazing around Stubb's Cross
Historic houses like Godinton House (about 3.3 miles north) are a reminder that the area around Stubb's Cross 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Ashford International station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Kingsnorth Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Stubb's Cross
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Keep an eye out for these signs:
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
Homes close to St Francis include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What the job involves on each surface
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- When we can work, for business premises
- How easy the joints are to reach
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.
How to look after the new joints
So the new joints stay in good condition:
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots aren’t blocked
- Wipe condensation off the frames
- Repaint timber before it’s bare
Most silicone sealants will not take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Should I try DIY first?
