External mastic in Sutton Wick

Do you need external mastic in Sutton Wick?

Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.

Signs it’s time to call us include:

  • Brick movement joints where the sealant has split
  • Rigid filler in a joint that should flex
  • Leaking joints around cladding and façade panels
  • Hard, crazed mastic that has stopped moving

In the older streets around Church of Saint Peter, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What your quote should include

  • How much experience the applicator has
  • What guarantee comes with the work
  • Which sealant they’ll use, and why
  • How long to leave it before use

How to choose a mastic man

External mastic for homes and businesses in Sutton Wick

External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. If you’re dealing with panel joints letting water in and joints pointed up with cement by mistake, we can put it right, on façade panels, render & cladding joints and copings & trims alike.

External sealant needs dry, clean surfaces, so work around Sutton Wick is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.

There’s a 12-month guarantee on every job, large or small.

Sutton Wick: your questions answered

Can you do external mastic in Sutton Wick?

Yes. Our work covers London and the South East, and Sutton Wick is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.

Do you cover smaller places like Sutton Wick?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.

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. Larger jobs naturally take longer, and we will tell you how long to expect.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.

Where are you based?

We work from Crawley. We cover Sutton Wick and the rest of Oxfordshire, along with the rest of our area.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

What does external mastic cost?

We do not 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. We agree the price before any work begins.

DIY versus a professional finish

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, 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.

The process

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. In a small place like Sutton Wick, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us about any previous sealing or DIY attempts
  • Let us know about stairs, lifts or work at height

Surface by surface

Brickwork movement joints

Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.

Concrete and blockwork

Blockwork and concrete shrink over time and move with the seasons. Their movement joints are sealed over backing rod with a flexible sealant.

Honest limits

We won’t take on work that will not last, so these are the limits:

  • Rising or penetrating damp from elsewhere in the wall
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Render that’s blown, hollow or coming away

If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Joints and surfaces we work on

  • Render & cladding joints
  • Brickwork movement joints
  • Façade panels
  • Copings & trims
  • Joints between brick and frames
  • Concrete & block

How we quote for external mastic

Jobs vary more than people expect. What affects the quote:

  • When we can work, for business premises
  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Helping us quote

What to tell us when you ask for a quote:

  • Pictures of the joints, sent by email
  • How we’d reach the joints
  • The problem you’ve noticed
  • Where the property is

How to look after the new joints

Looking after new joints is easy:

  • Never let anyone fill a movement joint with mortar
  • Keep high-pressure jets off the joints
  • Get split or bare joints resealed while the damage is small
  • Don’t let climbing plants root in the sealant

Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.

What external mastic looks like in Sutton Wick

With historic houses such as Clifton Hampden Manor (about 4.2 miles east) nearby, there’s older building stock in the area around Sutton Wick as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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 let a flat or house near Appleford station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Drayton Community Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
