Window Mastic in Redlands
Window and door frames in Redlands need attention? We remove the old material, prepare the joints and seal them properly.
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
Different surfaces, different methods
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.

How we quote for window mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether there’s mould to deal with
- How easy the joints are to reach
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
When you call or email, it’s useful to know:
- Roughly how big the job is
- Whether it’s a home or a business
- Where the job is, and your postcode
- A few pictures by email, if you can

Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Redlands, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What we do, step by step
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes most of a day for a typical house, less for a few frames, including the tidy-up. Somewhere like Redlands needs a little journey planning: 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.
- 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.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Repaint timber before it’s bare
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Common problems we fix in Redlands
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
People usually contact us after spotting something like this:
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
Rented homes near Farnham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- Who turns up on the day
- Whether the sealant suits the joint
- How the colour is chosen
- Whether VAT is included

Window mastic in Redlands: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Farnham Castle (about 2.3 miles south-east) are a reminder that the area around Redlands has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Crondall Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
