How we handle window mastic in Butler's Cross
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include hard, cracked sealant around windows and draughty joints inside around the window, on window sills, patio & French doors and aluminium frames.
In a village or hamlet like Butler's Cross, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Why deal with it now?
The work is quick compared with the damage it prevents: it 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. In a small place like Butler's Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Different surfaces, different methods
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Frames and glazing around Butler's Cross
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.
If you live in an older home near Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Little Kimble station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

When to call us in Butler's Cross
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
It’s worth asking for a quote if you see:
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
- Mastic that is falling out in pieces
- White mastic on grey or black frames
If you look after a building such as John Colet School, its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- Who turns up on the day
- Which sealant they’ll use, and why
- How the colour is chosen
- Whether all the old sealant comes out first
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ventilate rooms so frames do not stay wet inside
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
- Wash the frames with mild soapy water
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
FAQs for Butler's Cross

Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Do you seal inside as well as outside?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- A sash or casement that won’t close properly
- A door that needs adjusting, rehanging or new seals
- Condensation trapped between the panes
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Butler's Cross, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
