Sand mastic in Brooklands
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have silicone on a period window that looks wrong and mastic round period door frames that has failed, we can help, whatever the surface.
In a smaller place like Brooklands, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Whatever the size of the job, it’s backed by our one-year guarantee.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Housing providers, facilities teams and property managers book us too in Brooklands and across Surrey. Several sites can go on one quote, and we are fully insured for the work.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sand mastic in Brooklands: local notes
With historic houses such as Byfleet Manor (about 1.7 miles south) nearby, there’s older building stock in the area around Brooklands 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 is traditional sand mastic. 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.
For landlords with property near Weybridge station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Charles Borromeo, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Heathside School? Then the mastic around its windows and doors needs looking after like any other building’s.
Brooklands is about 1 mile south-west of Weybridge, in Surrey. Across the KT13 area, our applicators can take on sand mastic. Our Surrey coverage runs to 395 places, Brooklands among them. You can also see our page for London, roughly 19 miles from Brooklands.
Our applicators cover all of KT13 and KT14 for sand mastic. If you need sand mastic at a property on Segrave Close, Railton Close and Locke King Road or a nearby road, we can help.

We also cover St George's Hill (1 mile north-east), Byfleet (1 mile south), Weybridge (1 mile north-east), New Haw (1 mile west) and Whiteley Village (1 mile east). We also work in nearby towns such as Guildford (9 miles south-west), Woking (5 miles south-west), Camberley (12 miles west), Epsom (8 miles east), Redhill (15 miles south-east) and Ewell (9 miles east).
What’s near Brooklands
We work in homes and buildings around St George's College Weybridge, Woburn Park and Manby Lodge Infant School and the streets around them. Brooklands has its own railway station: Weybridge station. A little further out are No. 2 New Zealand General Hospital (2.7 miles north-east). For a walk, there’s Papercourt Marshes and Ferris Meadow Lake.
What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- Access and height
- How much there is to do
- How much old sealant there is and how hard it is to remove
- The type of sealant required
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
When you call or email, these details help:
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
How to look after the new joints
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. In a smaller place like Brooklands, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we look at the surrounds with you and agree what needs doing.
- 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.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

Common questions in Brooklands
I let a flat near Weybridge station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do sand mastic in Brooklands?
Yes, Brooklands is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll talk you through it.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
How long does the job take?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Masonry that needs repairing
- Timber that has rotted
- Decisions on consent for listed homes
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Joints and surfaces we work on
- Sash and case windows
- Period & listed homes
- Tenement windows
- Brick reveals
- Stone surrounds
- Timber door frames
Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Homes in smaller places like Brooklands can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
