What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. For a village or hamlet like Hempstead, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

About our window mastic in Hempstead
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on aluminium frames, composite doors and patio & French doors, and the jobs we see most are untidy mastic left by window fitters and a bead that doesn’t match the frame.
In a village or hamlet like Hempstead, 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.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What window mastic looks like in Hempstead
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Hempstead, as everywhere, window mastic is only as good as the preparation behind it.

Letting agents and landlords in Hempstead can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Hempstead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as that is a job for a joiner.

When to call us in Hempstead
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people generally mention when they call include:
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
For an older house near a landmark such as Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Don’t aim a pressure washer at the joints
- Paint up to the joint, not over it
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
