Window Mastic in Norton Mandeville

About our window mastic in Norton Mandeville
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We’re often asked to deal with mastic that’s falling out in pieces and mastic that has split away from the wall, across timber windows & doors, uPVC windows and window sills.
Somewhere as small as Norton Mandeville, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You get a 12-month guarantee, the same in Norton Mandeville as everywhere else we work.

What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Window mastic in Norton Mandeville: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like High Ongar Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
Why it’s worth doing now in Norton Mandeville
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like Norton Mandeville, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

How it works
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. In a small place like Norton Mandeville, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Clear the area around the work

What affects the cost of window mastic

- The number and length of the joints
- The type of sealant required
- How easy the joints are to reach
- How many rooms, windows or areas are involved
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Roughly how big the job is
- Where the job is, and your postcode
- If someone has resealed it before
Every job is quoted individually. Just phone 0345 464 0079 or email us with the details and send photos if you have them.
What we’re called out for in Norton Mandeville
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Common reasons people contact us are:
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- Draughty joints inside around the window
- Mastic that has split away from the wall
If you live in an older home near Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
