Window mastic for homes and businesses in Holloway
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we will say so. We’re often asked to deal with draughts coming in around windows and doors and leaking joints at the ends of sills, across aluminium frames, patio & French doors and composite doors.
In a village or hamlet like Holloway, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Surface by surface
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Frames and glazing around Holloway
Historic houses like Harleyford Manor (about 2.7 miles north-west) are a reminder that the area around Holloway 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 is traditional sand mastic. 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.
Schools such as Burchetts Green CofE Infants' School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Furze Platt station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Signs you need window mastic in Holloway
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Signs it’s time to call us include:
- Hard, cracked sealant around windows
- A bead that doesn’t match the frame
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
In the older streets around Saint John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Holloway can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
