Window Mastic in Godmersham
Problem with your window and door frames in Godmersham? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Old mastic that has gone black or come away
DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Window mastic in Godmersham, done properly
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. If you’re dealing with old mastic that has gone black or come away and water coming in at the bottom corners of a door, we can put it right, whatever the surface.
In a village or hamlet like Godmersham, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Quotes for window mastic in Godmersham
Jobs vary more than people expect. The main factors:
- Whether the work is at height
- How many areas need sealing
- Any working-time requirements on site
- The number and length of the joints
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or send us an email.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. Somewhere as small as Godmersham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Tell us about any water getting in

Advice
Why deal with it now?
Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Godmersham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why book with us
- Every job guaranteed for a year

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Windows and doors in Godmersham
Rainfall in the South East is lower than in much 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 Church of St Lawrence, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we’re called out for in Godmersham
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
It’s worth asking for a quote if you see:
- Cracked internal joints between frame and plaster
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
Rented homes near Chilham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

- What happens if the job turns out different
- Whether all the old sealant comes out first
