External mastic for homes and businesses in Binsted
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you have rain getting behind render or cladding at a joint and panel joints letting water in, we can put it right, whatever the surface.
Somewhere as small as Binsted, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
There’s a 12-month guarantee on every job, whatever its size.

Is Binsted in your area for external mastic?
Yes, Binsted is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
How do I get a quote for external mastic in Binsted?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What we do, step by step

Somewhere as small as Binsted, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.

- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Looking after it afterwards
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Get split or bare joints resealed while the damage is small
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
When to call us in Binsted
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Signs it’s time to call us include:
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Moss and dirt in joints with no sealant left
- Old sealant gone brittle and cracked
If you let a flat or house near Ford station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before booking
- The length of the guarantee
- Whether they’re fully insured
- Whether you can choose the colour
- Whether the sealant suits the joint

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Honest limits
A few problems are outside what sealant work can do:
- Damp that isn’t coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
