What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job normally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. For a village or hamlet like Althorne, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.

External mastic for homes and businesses in Althorne
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. If you have gaps where render, brick and frames meet and panel joints letting water in, we can help, on brickwork movement joints, joints between brick and frames and render & cladding joints alike.
Outside joints can only be sealed when they’re dry, so work in Althorne is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, in Althorne and everywhere else we cover.

Outside joints around Althorne
Althorne is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Parish Church of St Andrew, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Althorne station, split movement joints are easy to miss on a rental until damp shows inside.

Althorne: your questions answered
Is external mastic in a coastal place like Althorne any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
I let a flat near Althorne station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Why it’s worth doing now in Althorne
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Althorne, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
Why book with us

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Avoid pressure-washing directly into sealant joints
- Never let anyone fill a movement joint with mortar
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
What affects the cost of external mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- When we can work, for business premises
- Access and height
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Render that is blown, hollow or coming away
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
