Trusted external mastic in Finchingfield

External mastic for homes and businesses in Finchingfield

Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. Typical jobs include failed sealant between panels on a façade and moss and dirt in joints with no sealant left, across joints between brick and frames, brickwork movement joints and concrete & block.

Older homes in small places like Finchingfield may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

All our work comes with a one-year guarantee.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Leave it or put it right?

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. Older cottages and farmhouses around Finchingfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

  • White, clear, grey or another colour, product permitting

What’s an expansion joint in brickwork?

A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.

Is it OK to fill a movement joint with cement?

No. Rigid materials cannot move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.

Where are you based?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Why do you put foam in the joint first?

That’s backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.

Is there a guarantee?

Yes. Every job comes with our 12-month guarantee.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Different surfaces, different methods

Render joints

The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.

Concrete and blockwork

Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.

What we are called out for in Finchingfield

UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.

If you can see any of these, it’s time to have the joints looked at:

  • Weeds or debris growing in open joints
  • Damp patches traced to an open external joint
  • Hard, crazed mastic that has stopped moving
  • Failed seals between different materials

Around Finchingfield, as everywhere, external mastic is only as good as the preparation behind it.

10 questions to ask before booking

Outside joints around Finchingfield

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.

For an older house near a landmark such as Parish Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Never let anyone fill a movement joint with mortar
  • Walk round the building once a year and look at the joints
  • Have failed joints looked at early
  • Tell anyone working on the walls about the movement joints

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.

Small splits are the time to act. Then it’s a straightforward cut-out and reseal.

How it works

The work is kept neat and contained to the area we’re working on. The job generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Finchingfield needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any leaks or damp you’ve noticed
  • Keep children and pets away from the work area

Advice

For landlords and businesses

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes 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 that we can handle for you.
