Questions from Norton
Do you work for landlords with property near Barnham station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Is Norton 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.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How we handle sand mastic in Norton
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you’re dealing with old cement repairs round a window that have failed and old sand mastic that has cracked, crumbled or fallen out, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Norton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
Period and listed homes
A traditional finish suits a period property.
Timber door frames
Round a period front door, sand mastic gives the right look.
Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a small place like Norton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What happens on the day
At the end, we look at the finished work together. The visit itself generally takes a few hours for a single window, longer for several, depending on how much there is to do. Somewhere as small as Norton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Advice
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Sand mastic in Norton: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Goodwood House (about 2.9 miles north-west) are a reminder that the area around Norton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Ormiston Six Villages Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to The Parish Church of St Mary include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we quote for sand mastic
There’s no set price list, because no two jobs are the same. What we look at:
- The number and length of the joints
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- When we can work, for business premises
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- The type of property
- What’s wrong with the joints now
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
Do you need sand mastic in Norton?
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
These are the problems we’re asked about most:
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
- Draughts and rain around sash boxes
- Weathered mastic on the most exposed windows
For landlords with property near Barnham station, any sash windows need sound mastic to keep draughts and rain out.
