External mastic in Loxwood

What happens on the day

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. Somewhere as small as Loxwood, 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. The faces are brushed clean and primed where the product requires 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
  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height

Advice

External mastic in Loxwood

Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on joints between brick and frames, concrete & block and render & cladding joints, and people most often call us about joints where the bead has come unstuck and hard, crazed mastic that has stopped moving.

Somewhere as small as Loxwood, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What happens if it’s left?

Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Loxwood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Loxwood buildings and the weather

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you live in an older home near St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Loxwood Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Loxwood is about 9 miles west of Horsham, in West Sussex. Loxwood gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Loxwood is one of 371 towns and villages in West Sussex where we work. There’s also a page for Crawley, about 14 miles away.

Work in RH14 works the same way as everywhere else we cover. Local streets include High Street, Pond Close and Oak Grove, all of which we cover. Nearby, we also carry out external mastic in Ifold (1 mile south-west), Alfold Bars (1 mile north), Alfold (1 mile north), Plaistow (2 miles west) and Durfold Wood (3 miles west). We also work in nearby towns such as Crawley (14 miles east), Horsham (9 miles east), Broadfield (14 miles east), Storrington (11 miles south), Billingshurst (5 miles south-east) and Bewbush (13 miles east).

How the job changes by surface

Render joints

Water behind render can lead to blown patches. Resealing the joints early keeps water out.

Joints between dissimilar materials

Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Clear growth from the base of walls and joints
  • Show decorators and builders where the movement joints are
  • Deal with leaking gutters that soak the joints below
  • Keep movement joints as flexible joints, not mortar

Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted.

Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

Loxwood: your questions answered

Is there a guarantee on external mastic in Loxwood?

All our work, in Loxwood and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Do you cover Loxwood for external mastic?

Yes. We work across London and the South East, and Loxwood 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.

Do you use backing rod?

The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only.

What colours does the sealant come in?

We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before we start from the range available.

How often do external joints need resealing?

That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.

Should I point up the gap in my brickwork?

No. Cement or mortar can’t stretch, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.

Can landlords and businesses book you?

Yes. We work in homes, commercial premises and hotels.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

When it is not the sealant

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Subsidence or other structural problems
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Loose or hollow render, which needs re-rendering

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
