Sand mastic in Aveley
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you’re dealing with mastic that needs renewing before redecorating and open joints round the window box, we can put it right, on tenement windows, sash and case windows and period & listed homes alike.
Houses in smaller places like Aveley can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
You get a 12-month guarantee, the same in Aveley as everywhere else we work.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Do not run silicone over sand mastic
- Clear gutters so water doesn’t pour onto the windows
- Renew mastic before redecorating the windows
- Leave the new mastic unpainted
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Why it’s worth doing now in Aveley
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a smaller place like Aveley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Do you need sand mastic in Aveley?
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
Look out for these signs:
- Cement or filler used on old window joints that has cracked
- Modern sealant on a period surround
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
If you live in an older home near Church of St Michael, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before booking
- What product goes in the joint
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- Is VAT in the price?
What the job involves on each surface
Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Parking around Aveley is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

Landlords, agents and businesses in Aveley
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
What affects the quote in Aveley
We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
To make quoting easier, please include:
- The type of property
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Roughly how big the job is

Frames and glazing around Aveley
Historic houses like Rainham Hall (about 2.9 miles north-west) are a reminder that the area around Aveley has older buildings as well as new. 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. 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.
Letting a property close to Purfleet station? Then any sash windows need sound mastic to keep draughts and rain out. Managing a site like Ormiston Park Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.
