Sand mastic for homes and businesses in Weybridge
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Typical jobs include cement or filler used on old window joints that has cracked and cracked mastic round a front door frame, on sash and case windows, brick reveals and period & listed homes.
Weybridge mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
There’s a 12-month guarantee on every job, whatever its size.

What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a single window, longer for several. Parking in a town like Weybridge is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We also work for property managers and facilities teams. Several sites can go on one quote.
Sand mastic in Weybridge: local notes
With historic houses such as Byfleet Manor (about 2.9 miles south) nearby, there’s older building stock in the area around Weybridge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Weybridge station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around United Reform Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

- Sash and case windows
- Brick reveals
- Stone surrounds
- Tenement windows
- Timber door frames
- Period & listed homes
Aftercare tips
So the new joints stay in good condition:
- Don’t paint over the new mastic
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
Different surfaces, different methods
Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Period and listed homes

Weybridge: your questions answered
Do you work for landlords with property near Weybridge station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Is there a guarantee on sand mastic in Weybridge?
All our work, in Weybridge and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or send us an email.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What we’re called out for in Weybridge
Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.
These are the problems we are asked about most:
- Mastic worn away on windows facing the weather
- Silicone on a period window that looks wrong
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
Schools such as St James CofE Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Whether all the old sealant comes out first
- How long to leave it before use
- What guarantee comes with the work
- How much experience the applicator has
