Surface by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
How we handle sand mastic in Henham
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We are often asked to deal with weathered mastic on the most exposed windows and gaps where the frame meets the masonry, on tenement windows, timber door frames and sash and case windows.
Homes in small places like Henham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

How we quote for sand mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- The size of the job
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- A few photos by email, if you can
- Access, such as stairs, a lift or height
- The address or postcode of the job

When it isn’t the sealant
A few problems are outside what sealant work can do:
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
- Cracked or broken glass
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

Henham: your questions answered
Is Henham in your area for sand mastic?
Yes, Henham is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Yes. We’re fully insured for domestic and commercial work.

Henham homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Horham Hall (about 2.7 miles east) nearby, there’s older building stock in the area around Henham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Elsenham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.

How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. For a village or hamlet like Henham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
How to get a quote

Advice
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are 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 does not work out, we can still put it right.
Landlord and commercial work in Henham
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
For anyone letting property in or around Henham, several properties can go on one quote. Send us the addresses and the work at each.
When to call us in Henham
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Look out for these signs:
- Failed mastic on an exposed elevation
- Cracked mastic round a front door frame
- Mastic that needs renewing before redecorating
- Wind and rain getting in round a sash window
Schools such as Henham and Ugley Primary and Nursery School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether they seal over old material or remove it
- How much experience the applicator has
- How the colour is chosen
- Whether they’re fully insured
