Window mastic in Church Crookham
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. Typical jobs include cracked sealant at the sill ends and gaps between the frame and the inside reveal, on window sills, composite doors and patio & French doors.
Homes in small places like Church Crookham 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.
All our work is covered by a one-year guarantee.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
- Ventilate rooms so frames don’t stay wet inside
- Avoid harsh chemicals near the mastic
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a morning for a couple of windows and a door. Somewhere like Church Crookham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, 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
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules

Window mastic in Church Crookham: local notes
Historic houses like Farnham Castle (about 3.5 miles south) are a reminder that the area around Church Crookham has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Fleet station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Fleet Spiritualist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Velmead Junior School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Church Crookham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

What the job involves on each surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain cannot run into the wall.
