Window mastic in Bannister Green, done properly
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. We work on patio & French doors, aluminium frames and window sills, and people most often call us about a bead that doesn’t match the frame and gaps where the sill meets the wall.
Mastic can only go onto a dry, clean joint, so window work in Bannister Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, in Bannister Green and everywhere else we cover.

How the visit works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work generally takes a morning for a couple of windows and a door. Somewhere as small as Bannister Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Advice
What the job involves on each surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Honest limits
It helps to know what we can’t do:
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
When to call us in Bannister Green
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.
If you can see any of these, it’s time to have the joints looked at:
- Mastic that has split away from the wall
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
Rented homes near Braintree station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Bannister Green questions
Is Bannister Green within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Braintree station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is it worth trying 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.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What does window mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Are you insured?
Yes. Full insurance covers our work.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Around Bannister Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
