External mastic in Badshot Lea, done properly

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you are dealing with joints pointed up with cement by mistake and cracked joints where brick meets render or frames, we can put it right, on render & cladding joints, copings & trims and joints between brick and frames alike.

Outside joints can only be sealed when they’re dry, so work in Badshot Lea is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What we’re called out for in Badshot Lea

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.

Common reasons people contact us include:

  • Cracked joints where brick meets render or frames
  • Moss and dirt in joints with no sealant left
  • Brick movement joints where the sealant has split
  • Rigid filler in a joint that should flex

If you let a flat or house near Aldershot station, split movement joints are easy to miss on a rental until damp shows inside.

Choosing a sealant specialist

What the job involves on each 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.

Copings and trims

Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.

Why deal with it now?

Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In a small place like Badshot Lea, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Walls and rooflines in Badshot Lea

Historic houses like Farnham Castle (about 1.8 miles south-west) are a reminder that the area around Badshot Lea has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.

Homes close to St George's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Badshot Lea Village Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

For landlords and businesses

If you manage several properties in or around Badshot Lea, several properties can be quoted together. Send us the addresses and the work at each.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

What happens on the day

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Badshot Lea 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 look at every joint and agree a colour to suit the wall.
  2. We take out the old sealant until the faces are sound.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in

When it is not the sealant

Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:

  • Walls that need new movement joints cut into them
  • Failed render or damaged cladding panels
  • Cracking across the wall rather than at a joint

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

Surfaces we seal

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