Chafford Hundred Sand Mastic
We cover Chafford Hundred for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
Sand mastic in Chafford Hundred, done properly
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you have draughts and rain around sash boxes and open joints round the window box, we can put it right, whatever the surface.
In a smaller place like Chafford Hundred, 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.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What sand mastic looks like in Chafford Hundred
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Tudor Court Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Grays station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Signs you need sand mastic in Chafford Hundred
Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they usually need raking out.
The problems people usually mention when they call include:
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
If you live in an older home near All Saints' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- When the joint can take water or movement
- How much experience the applicator has
- Whether VAT is included
- Which colour the sealant will be
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Chafford Hundred, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Quotes for sand mastic in Chafford Hundred
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Any working-time requirements on site
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
What to tell us for a quote
When you call or email, it’s useful to know:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Roughly how big the job is
- Photos by email, if that is easy
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Inspect the joints round the windows every year or so
- Clear gutters so water does not pour onto the windows
- Check with your local planning authority if your home is listed
- Plan mastic work ahead of painting
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
The process
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours for a single window, longer for several. A visit to Chafford Hundred is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
