Sand Mastic in Chignall Smealy
Traditional burnt sand mastic around sash and case windows and doors in stone and brick in Chignall Smealy, with a one-year guarantee on every job. Call for a quick quote.
- Tired mastic found when preparing windows for paint
- Mastic worn away on windows facing the weather
- Patchy fillers round a sash window
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a small place like Chignall Smealy, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Why us?
- Over 20 years’ experience
- Full insurance on every job
- Tidy, careful work
- Anti-fungal silicone where joints get wet
About our sand mastic in Chignall Smealy
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on stone surrounds, brick reveals and period & listed homes, and people most often call us about modern sealant on a period surround and mastic that needs renewing before redecorating.
Mastic can only go onto a dry, clean joint, so window work in Chignall Smealy is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

When to call us in Chignall Smealy
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Common reasons people contact us are:
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
- Open joints round the window box
- Cracked mastic round a front door frame

Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We’ll give you a better idea when we quote.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Chignall Smealy, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

DIY sealant or a professional job?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Brick reveals
- Sash and case windows
- Timber door frames
- Stone surrounds
- Period & listed homes
- Tenement windows
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Windows and doors in Chignall Smealy
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hylands (about 4.7 miles south) are a reminder that the area around Chignall Smealy has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Newlands Spring Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
