How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. In a small place like Amport, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Mention any tricky access

External mastic for homes and businesses in Amport
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. If you’re dealing with joints with sealant missing in places and failed seals between different materials, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Amport is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work comes with our 12-month guarantee.

When something else is needed
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Loose or hollow render, which needs re-rendering
- Damp that is not coming from the joint
- Walls that need new movement joints cut into them
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Render & cladding joints
- Façade panels
- Copings & trims
Walls and rooflines in Amport
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Amport Church of England Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How to look after the new joints
So the new joints stay in good condition:
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
- Make sure movement joints are not pointed over
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
Surface by surface
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Amport questions
Do you cover Amport for external mastic?
Yes. We work across London and the South East, and Amport is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Grateley station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a 12-month guarantee.
Can you seal joints between two different materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Bigger jobs take longer, and we’ll tell you how long to expect.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- The size of the job
- Mould in or behind the old joints
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before work begins.

What we are called out for in Amport
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
People usually contact us after spotting one of these:
- Old sealant gone brittle and cracked
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Failed seals between different materials
If you let a flat or house near Grateley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
