How do I get a quote for window mastic in Broadgate?

Is the work guaranteed?
Yes. Each job is covered for 12 months.
Different surfaces, different methods
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are. In a small place like Broadgate, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Keep children and pets away from the work area
- Mention any tricky access
- Tell us if parking is tricky

Advice
When to call us in Broadgate
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Most people get in touch after spotting one of these:
- A bead that does not match the frame
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
If you live in an older home near Church of St Mark, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Who turns up on the day
- Which sealant they’ll use, and why
- What the cure time is
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. Resealing now is a small job by comparison. Around Broadgate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

When it is not the sealant
We’ll always be straight with you, so here’s what sealant can’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp problems in the wall away from the window

Frames and glazing around Broadgate
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. With historic houses such as South Stoneham House (about 4.9 miles south) nearby, there’s older building stock in the area around Broadgate as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Ampfield Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Chandlers Ford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into 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.
