Window mastic for homes and businesses in Bulls Cross
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Common call-outs are for untidy mastic left by window fitters and draughts coming in around windows and doors, on patio & French doors, aluminium frames and window sills. We are sealant specialists rather than general builders, which means window mastic in Bulls Cross is done by people who seal joints every day.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Bulls Cross as anywhere.
Your job is guaranteed for a year, as with all our work.

Frames and glazing around Bulls Cross
With historic houses such as Forty Hall (about 0.7 miles south-west) nearby, there’s older building stock in the area around Bulls Cross as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
For an older house near a landmark such as Jesus Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Turkey Street 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. As a London address, Bulls Cross can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes most of a day for a typical house, less for a few frames. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can

Advice
Different surfaces, different methods
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that.
Should I try it myself first?
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 fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Clean frames with a soft cloth and soapy water
- Do not aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What affects the quote in Bulls Cross
We don’t publish a price list. The quote depends on:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- Whether there’s mould to deal with
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What we need to know
Photos help, but a description is a good start. Try to tell us:

- Where the property is
