Window mastic in Bredgar
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with mastic that has split away from the wall and gaps left after new windows were fitted, we can put it right.
In a village or hamlet like Bredgar, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

How we quote for window mastic
Every job gets its own quote. These are the things that affect it:
- Mould in or behind the old joints
- When we can work, for business premises
- How easy the joints are to reach
- The number and length of the joints
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- The type of property
- A few photos by email, if you can
- Whether it has been sealed before
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
Landlords, agents and businesses in Bredgar
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Bredgar homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Sittingbourne station, renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Bredgar Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Why act early in Bredgar
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. In a small place like Bredgar, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- More than 20 years in sealant work
- Fully insured
- Neat joints and a tidy finish
- Every job guaranteed for a year

What we’re called out for in Bredgar
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Look out for these signs:
- Rushed sealant from a window installation
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
For an older house near a landmark such as Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
