About our window mastic in Benover
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you’re dealing with damp patches on the reveal after heavy rain and rushed sealant from a window installation, we can help, whatever the surface.
Homes in small places like Benover often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You get a one-year guarantee, the same in Benover as everywhere else we work.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

FAQs for Benover
Is Benover within the area you cover?
Yes, Benover is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Yes, Benover is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Are you an approved applicator?

Is there any odour?

Can tenants book the work?

Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Don’t use solvent cleaners on the joint
- Ventilate rooms so frames do not stay wet inside
- Paint up to the joint, not over it
- Make sure the drainage slots are not blocked
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Frames and glazing around Benover
The South East is one of 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 Yalding station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Hunton Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Signs you need window mastic in Benover
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
The problems people generally mention when they call include:
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Damp patches on the reveal after heavy rain
- Mastic that is falling out in pieces
If you live in an older home near St Peter's and St Paul's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- What insurance they hold
- What product goes in the joint
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Around Benover, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a few frames, or a day or more for a whole house.

- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
