How it works
Once we are on site, 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 per window, depending on the condition of the joints. Somewhere like Epping Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit

About our sand mastic in Epping Green
Across Epping Green, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on brick reveals, stone surrounds and sash and case windows, and the jobs we see most are mastic dropping out of the joint and a silicone bead on a sash window that spoils the look.
Mastic can only go onto a dry, clean joint, so window work in Epping Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Epping Green as everywhere else we work.

Sand mastic in Epping Green: local notes
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. With historic houses such as Hill Hall (about 4.9 miles south-east) nearby, there’s older building stock in the area around Epping Green as well as newer homes. 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.
Schools such as Epping Upland CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Roydon station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What happens if it’s left?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. In a small place like Epping Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Have rotten timber repaired before new mastic goes in
- Ask us before painting near the mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What affects the cost of sand mastic
You’ll get a clear quote before we start. It’s based on:
- Working hours on commercial sites
- The product the joint needs
- The number and length of the joints
- Any mould that needs treating
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
When you call or email, it’s useful to know:
- Whether it has been sealed before
- The rough size of the job
- How we’d reach the joints
- Where the property is
If you’re in Epping Green and need sand mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Do you need sand mastic in Epping Green?
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The problems people generally mention when they call are:
- Gaps round a timber door in stone or brick
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Old sand mastic that has cracked, crumbled or fallen out
In the older streets around Church of All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in.
