Common questions in Epping
Is sand mastic in Epping guaranteed?
All our work, in Epping and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Will you come out to Epping?
Yes. Epping is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Sand mastic in Epping, done properly
Across Epping, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We’re often asked to deal with gaps between timber frames and stone or brick and a silicone bead on a sash window that spoils the look, on stone surrounds, period & listed homes and tenement windows.
In a smaller place like Epping, 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.
All our work is covered by a one-year guarantee, wherever you are in Essex.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours per window, depending on the condition of the joints. Parking around Epping is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Tell us about any water getting in

Related advice
What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Homes in smaller places like Epping can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs

What the job involves on each surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Epping homes and the weather
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. With historic houses such as Hill Hall (about 2.5 miles south-east) nearby, there’s older building stock in the area around Epping as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common problems we fix in Epping
Timber frames move with the seasons. The movement cracks the mastic over time.
If you can see any of these, it’s time to have the joints looked at:
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
Schools such as Epping 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
- What the cure time is
- What the quote includes, VAT included or not
- How much experience the applicator has
- How the joint is cleaned and prepared
Honest limits
