Aftercare tips

To keep the joints looking good and working properly:

  • Act on the first splits you see
  • Clear growth from the base of walls and joints
  • Check the sealant is paintable before painting near it
  • Wash walls gently around the sealant

Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.

Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

External mastic in Ickford, done properly

Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include joints where the bead has come unstuck and failed seals between different materials, across façade panels, concrete & block and joints between brick and frames.

Around Ickford, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

If you manage several properties in or around Ickford, several properties can be quoted together. Just tell us the addresses and what each one needs.

Why deal with it now?

It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Where a wall is exposed, as many are in small places like Ickford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Signs you need external mastic in Ickford

Every building moves. 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.

The most common problems we see are:

  • Damp patches traced to an open external joint
  • Rigid filler in a joint that should flex
  • Weathered mastic that no longer stretches
  • Plants rooting in failed movement joints

For an older house near a landmark such as Parish Church of St Nicholas, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Choosing a sealant specialist

Walls and rooflines in Ickford

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Boarstall Tower (about 4.5 miles north) nearby, there’s older building stock in the area around Ickford as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

For site and facilities teams at buildings such as Ickford School, its movement joints, gutters and trims need looking after like any other building’s.

Questions from Ickford

Will you come out to Ickford?

Yes, Ickford is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you cover Ickford for external mastic?

Yes. We work across London and the South East, and Ickford is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

How long does external mastic take?

Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we will say how long yours will take.

Do you work at height?

It depends on the height and the site. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.

How do I get a quote for external mastic in Ickford?

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. You’ll get a clear quote before any work starts.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours to a few days, depending on the length of joint and the access from start to finish. Somewhere as small as Ickford, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Clear items away from the joints we are working on
  • Mention if the joints have been sealed before
  • Let us know about stairs, lifts or work at height
