Leave it or put it right?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Laughton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, 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.

About our sand mastic in Laughton
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you have gaps between timber frames and stone or brick and patchy fillers round a sash window, we can help.
Homes in small places like Laughton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What affects the cost of sand mastic
Call for a quick quote. The main things that affect it are:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether the work is at height
- How much there is to do
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Asking for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Whether it’s a home or a business
- The problem you’ve noticed
- The rough size of the job
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
- Don’t run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Do you need sand mastic in Laughton?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Most people get in touch after spotting something like this:
- Old cement repairs round a window that have failed
- Mastic that needs renewing before redecorating
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
Managing a site like Laughton Community Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What the cure time is
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
- What product goes in the joint
Laughton questions
I let a flat near Glynde station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Laughton?
Yes. Laughton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints. In a small place like Laughton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Sand mastic in Laughton: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Glyndebourne (about 3.4 miles south-west) are a reminder that the area around Laughton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Glynde station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near The Parish Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
