External mastic in Brambridge

The process

Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. Somewhere like Brambridge needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, the joints are inspected and the access agreed.
  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. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Mention any tricky access
  • Tell us if parking is tricky

External mastic in Brambridge

On houses, flats and commercial buildings across Brambridge, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Common call-outs are for hard, crazed mastic that has stopped moving and movement joints filled with mortar instead of sealant, on copings & trims, joints between brick and frames and render & cladding joints.

Outside joints can only be sealed when they’re dry, so work in Brambridge is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.

A one-year guarantee comes as standard.

What affects the cost of external mastic

Call for a quick quote. The main things that affect it are:

  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site
  • The number of rooms or windows
  • The type of sealant required

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • How we’d reach the joints
  • Pictures of the joints, sent by email
  • How many joints, rooms or windows are involved
  • The problem you’ve noticed

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Look over the joints every year, ideally after winter
  • Keep soil, plants and ivy away from the joints
  • Avoid pressure-washing directly into sealant joints
  • Keep movement joints as flexible joints, not mortar

If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.

Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.

DIY versus a professional finish

If you’re set on DIY, put the effort into 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.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Surface by surface

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.

Concrete and blockwork

The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.

Common questions in Brambridge

Can you do external mastic in Brambridge?

Yes. We work across London and the South East, and Brambridge is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Can you help a landlord with a rental near Shawford station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.

Where is Mr Mastic based?

We work from Crawley. We cover Brambridge and the rest of Hampshire, along with the rest of our area.

Can new sealant go over the old?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

How long will you be here?

Typically it takes a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer.

What information do you need?

Tell us what needs doing and where. If we need more, we’ll ask.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Brambridge buildings and the weather

With historic houses such as South Stoneham House (about 4.5 miles south-west) nearby, there’s older building stock in the area around Brambridge as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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 landlords with property near Shawford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Colden Common Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of the Holy Trinity, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Brambridge is about 2 miles north-east of Eastleigh, in Hampshire.

Honest limits

It helps to know what we cannot do too:

  • Loose or hollow render, which needs re-rendering
  • Structural movement, which needs a surveyor or engineer
  • Cracked brickwork or render that needs a builder or plasterer

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
