Window & door mastic in Bedham, West Sussex
Window and door frames in Bedham need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
When to call us in Bedham
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
Managing a site like Fittleworth CofE Village School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Window mastic in Bedham
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We work on uPVC windows, aluminium frames and composite doors, and common reasons people get in touch are whistling draughts around closed windows and cracked sealant at the sill ends.
Outdoor sealant needs dry, clean surfaces, so work on frames around Bedham is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by a one-year guarantee.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames. Somewhere as small as Bedham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Leave it or put it right?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Where a wall is exposed, as many are in small places like Bedham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Bedham homes and the weather
With historic houses such as Old Place Manor (about 2.2 miles east) nearby, there’s older building stock in the area around Bedham 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Pulborough station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as The Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the job changes by surface
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
