Doleham Window Mastic
Window mastic across Doleham and nearby, with old sealant always removed completely and a one-year guarantee.
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Rushed sealant from a window installation
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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.
Window mastic for homes and businesses in Doleham
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 and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you are dealing with sealant in the wrong colour for the frame and gaps left after new windows were fitted, we can help, whatever the surface.
Somewhere as small as Doleham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Every job is covered by our 12-month guarantee, wherever you are in East Sussex.

How the job changes by surface
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Common problems we fix in Doleham
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.
The problems people generally mention when they call are:
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- Gaps left after new windows were fitted
- Leaking joints at the ends of sills
Homes close to The Parish Church of St George include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- How the surfaces are prepared before sealing

Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Doleham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes most of a day for a typical house, less for a few frames. Somewhere as small as Doleham, 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.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Frames and glazing around Doleham
London and the South East are among 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 Durhamford Manor (about 3.9 miles north-west) nearby, there’s older building stock in the area around Doleham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Doleham station, renewing tired window mastic between tenants heads off draught and damp complaints.
