FAQs for Cade Street
Is window mastic in Cade Street guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do window mastic in Cade Street?
Yes, Cade Street is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What information do you need?
A short description and the location. If we need more, we’ll ask.
How much does window mastic cost in Cade Street?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal.
When to call us in Cade Street
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Look out for any of the following:
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
For an older house near a landmark such as The Parish Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep paint off silicone joints
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Cade Street homes and the weather
Historic houses like Bateman's (about 4.7 miles east) are a reminder that the area around Cade Street has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Heathfield Community College, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a small place like Cade Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of frames, longer for a whole house. Somewhere like Cade Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention if the joints have been sealed before
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
