External mastic in Great Totham, done properly
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on concrete & block, copings & trims and joints between brick and frames, and the jobs we see most are failed sealant between panels on a façade and sealant pulling away from one side of the joint.
Houses in smaller places like Great Totham can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are usually the first to go.
All of our work is guaranteed for twelve months, in Great Totham and everywhere else we cover.

Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Great Totham: your questions answered
Is Great Totham within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Great Totham?
Yes. Our work covers London and the South East, and Great Totham is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Make sure movement joints are not pointed over
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
- Have failed joints looked at early
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Outside joints around Great Totham
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Witham station, split movement joints are easy to miss on a rental until damp shows inside.

What’s near Great Totham
Locally, jobs take us to homes and businesses close to The Bull Public House and the streets around them. The closest station to Great Totham is Witham station, roughly 3.1 miles north-west. A little further out are Maldon & District Agricultural & Domestic Museum (3.4 miles south-east). For a walk, there’s Shut Heath Wood.
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In an older home around Great Totham, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Do you need external mastic in Great Totham?
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Most people get in touch when they notice something like this:
- Leaking joints around cladding and façade panels
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
Managing a site like Great Totham Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a smaller place like Great Totham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Clear the area around the work

Advice
What affects the cost of external mastic
Your quote is based on your job. We take into account:
- The number and length of the joints
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
When you contact us, these details help:
- The rough size of the job
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- Where the property is
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand.
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
- Render that is blown, hollow or coming away
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
