Why it’s worth doing now in Old Dean
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a smaller place like Old Dean, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Window mastic for homes and businesses in Old Dean
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on window sills, aluminium frames and composite doors, and the jobs we see most are damp patches on the reveal after heavy rain and draughts coming in around windows and doors.
Homes around Old Dean range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Every job comes with a one-year guarantee, wherever you are in Surrey.

Landlord and commercial work in Old Dean
We work for letting agents and landlords as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Parking around Old Dean is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

When to call us in Old Dean
Water runs down the glass onto the sill, 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.
Keep an eye out for any of the following:
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- Gaps between the frame and the inside reveal
For landlords with property near Camberley station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Before you book anyone
- The length of the guarantee
- What insurance they hold
- How long to leave it before use

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Windows and doors in Old Dean
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Martin's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Collingwood College? Then the mastic around its windows and doors needs looking after like any other building’s.
