Landlord and commercial work in West Hendred
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Should I try it myself 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Other services in West Hendred
Do you need window mastic in West Hendred?
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Look out for any of the following:
- Untidy mastic left by window fitters
- Mastic that is falling out in pieces
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
In the older streets around Church of the Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone
- When the joint can take water or movement
- Who turns up on the day
- Whether they’re fully insured
- Is the old sealant removed completely?
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep solvents and bleach off the sealant
- Ventilate rooms so frames do not stay wet inside
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Why it’s worth doing now in West Hendred
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around West Hendred, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Questions from West Hendred
Is West Hendred within the area you cover?
Yes, West Hendred is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Didcot Parkway station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Can resealing stop a draught around my window?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
West Hendred homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
