Window mastic for homes and businesses in Norton Green
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for black, perished sealant on frames and rain getting in at the frame or under the sill, on window sills, patio & French doors and timber windows & doors.
In a village or hamlet like Norton Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What the job involves on each surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Landlords, agents and businesses in Norton Green
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
How it works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Norton Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

FAQs for Norton Green
Will you come out to Norton Green?
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.
Does living near the coast affect window mastic in Norton Green?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Frames and glazing around Norton Green
Norton Green is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Mottistone Manor (about 4.9 miles south-east) are a reminder that the area around Norton Green 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 is traditional sand mastic.
Managing a site like All Saints Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around All Saints' Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Around Norton Green
Around Norton Green, our work takes us to homes and buildings near The Red Lion pub and the streets around them.

When to call us in Norton Green
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
These are the problems we’re asked about most:
- Sealant in the wrong colour for the frame
- Draughty joints inside around the window
- Untidy mastic left by window fitters
- Cold air getting in at the frame edge
Letting a property close to Lymington Pier station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Why act early in Norton Green
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. Where a wall is exposed, as many are in small places like Norton Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why book with us
- Old sealant always removed completely
- Experience in homes, commercial sites and hotels
- Colour agreed with you before we start
- One-year guarantee on every job

Aftercare tips
After the cure time, these simple habits help:
- Keep solvents and bleach off the sealant
- Don’t paint over the silicone
- Ventilate rooms so frames do not stay wet inside
- Make sure the drainage slots aren’t blocked
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
