Sand mastic for sash & case windows in Lidsey, West Sussex
Window and door surrounds in Lidsey need attention? We remove the old material, prepare the joints and seal them properly.
- Draughty sash windows at the surround
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
How to look after the new joints
Aftercare is simple:
- Avoid heavy scraping on the mastic joint
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Sand mastic for homes and businesses in Lidsey

We work on period & listed homes, timber door frames and tenement windows, and common reasons people get in touch are cement or filler used on old window joints that has cracked and mastic that needs renewing before redecorating.

What affects the quote in Lidsey
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- The number of rooms or windows
- Whether the work is at height
- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Where the property is
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved and send you a clear quote.

Frames and glazing around Lidsey
Lidsey is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Goodwood House (about 4.9 miles north-west) nearby, there’s older building stock in the area around Lidsey 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.
Schools such as Aldingbourne Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around The Parish Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Lidsey is about 2 miles north-east of Bognor Regis, in West Sussex. Lidsey gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

Why it’s worth doing now in Lidsey
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like Lidsey, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes a few hours for a single window, longer for several. In a small place like Lidsey, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

FAQs for Lidsey

Do you cover smaller places like Lidsey?
Yes. Lidsey is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you an approved applicator?

Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
How long does sand mastic take to harden?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
Is consent needed for window work on a listed home?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.

A typical job takes anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. We will confirm how long when we quote.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
What we’re called out for in Lidsey

Signs it’s time to call us include:
- Mastic worn away on windows facing the weather
- Old cement repairs round a window that have failed
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window

How the job changes by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. We shape it by hand to follow the stone.
