How we handle sand mastic in Iford
Across Iford, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on sash and case windows, brick reveals and tenement windows, and common reasons people get in touch are patchy fillers round a sash window and draughts and rain around sash boxes.
In a village or hamlet like Iford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months.

Frames and glazing around Iford
With historic houses such as Monk's House (about 1.4 miles south-east) nearby, there’s older building stock in the area around Iford as well as newer homes. 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Lewes station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Iford and Kingston Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Iford
Do you work for landlords with property near Lewes station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Iford?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick normally suit sand mastic and newer frames generally get a flexible sealant.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
How the visit works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a single window, longer for several from start to finish. Somewhere as small as Iford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- 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.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Advice
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.
Why act early in Iford
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Iford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- More than 20 years in sealant work
- We never seal over old sealant
- Neat joints and a tidy finish
- Every job guaranteed for a year

How to look after the new joints
So the new joints stay in good condition:
- Look over the window mastic once a year
- Get any rot dealt with first
- Go gently near the mastic when preparing windows
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Signs you need sand mastic in Iford
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Common reasons people contact us include:
- Wind and rain getting in round a sash window
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
If you live in an older home near St Pancras Church (Kingston near Lewes), the joint between an old wall and a newer frame is generally the first place rain gets in.
