Sand mastic for homes and businesses in Kirdford
We work across Kirdford renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. Common call-outs are for wind and rain getting in round a sash window and patchy fillers round a sash window, across stone surrounds, timber door frames and sash and case windows.
Around Kirdford, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Kirdford and everywhere else we cover.

How the job changes by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.

Why it’s worth doing now in Kirdford
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Where a wall is exposed, as many are in small places like Kirdford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Tidy, careful work
- Sanitary silicone with an anti-fungal additive in wet areas
- Full insurance on every job
- We never seal over old sealant

Kirdford homes and the weather
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. With historic houses such as Petworth House (about 4.1 miles south-west) nearby, there’s older building stock in the area around Kirdford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Billingshurst station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Kirdford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention any tricky access
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children

Common questions in Kirdford
Will you come out to Kirdford?
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.
Do you cover Kirdford for sand mastic?
Yes. We work across London and the South East, and Kirdford is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can you match the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Common problems we fix in Kirdford
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
Signs it’s time to call us include:
- Tired mastic found when preparing windows for paint
- Wind and rain getting in round a sash window
- Patchy fillers round a sash window
- Mastic worn away on windows facing the weather
In the older streets around The Parish Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone
- What the quote includes, VAT included or not
- The length of the guarantee
- Whether all the old sealant comes out first
- What insurance they hold
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
What affects the cost of sand mastic
The quote reflects the job in front of us. We take into account:
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- The number and length of the joints
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
What we need to know
There’s no need for technical detail. Just tell us:
- The type of property
- What’s wrong with the joints now
- Where the property is
- How many joints, rooms or windows are involved
Every job is quoted individually. Simply ring 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Landlords, agents and businesses in Kirdford

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
