About our window mastic in Cross-at-Hand
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you’re dealing with white mastic on grey or black frames and leaking joints at the ends of sills, we can put it right, on patio & French doors, window sills and composite doors alike.
Mastic can only go onto a dry, clean joint, so window work in Cross-at-Hand is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
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.

Frames and glazing around Cross-at-Hand
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Stoneacre (about 4.6 miles north) nearby, there’s older building stock in the area around Cross-at-Hand as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Staplehurst station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What happens if it’s left?
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, using a product chosen for the frame and wall. Around Cross-at-Hand, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. Somewhere as small as Cross-at-Hand, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

Advice
What we are called out for in Cross-at-Hand
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
Most people get in touch when they notice one of these:
- Whistling draughts around closed windows
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
Stoneacre, about 4.6 miles north, is one of the historic houses in the wider area around Cross-at-Hand, and older homes nearby need a sealant that suits their walls.

Can I add another job to the visit?

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Quotes for window mastic in Cross-at-Hand
The price is agreed before any work begins. It takes into account:
- Any working-time requirements on site
- Access and height
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before any work starts.
Helping us quote
To make quoting easier, please include:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Aftercare tips
Looking after new joints is easy:
- Keep timber frames painted
- Keep jet washers away from the mastic
- Make sure the drainage slots aren’t blocked
- Don’t paint over the silicone
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
