About our sand mastic in West Thurrock
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. If you have patchy fillers round a sash window and tired mastic found when preparing windows for paint, we can help.
Homes around West Thurrock range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a 12-month guarantee.

What the job involves on each surface
Period and listed homes
Materials matter on listed and conservation-area homes. Like-for-like sand mastic is generally favoured.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes a few hours for a single window, longer for several. For a job in West Thurrock, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Advice
FAQs for West Thurrock
Is West Thurrock in your area for sand mastic?
Yes. Our work covers London and the South East, and West Thurrock is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Do you cover smaller places like West Thurrock?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I use sand mastic or silicone?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames usually get a flexible sealant.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Aftercare tips
Looking after new joints is easy:
- Do not paint over the new mastic
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Don’t run silicone over sand mastic
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
What affects the cost of sand mastic
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- Whether there’s mould to deal with
- How many areas need sealing
- Whether the work is at height
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 the work is at height. We take all of that into account in your quote.
Helping us quote
To make quoting easier, please include:
- Whether it’s a home or a business
- How we’d reach the joints
- The rough size of the job
- If someone has resealed it before
There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or drop us an email.
Frames and glazing around West Thurrock
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Rainham Hall (about 4.7 miles north-west) are a reminder that the area around West Thurrock has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as West Thurrock Academy, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Clement's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Why act early in West Thurrock
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In an older home around West Thurrock, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
