About our external mastic in Upton

Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. If you have gaps where render, brick and frames meet and rain getting behind render or cladding at a joint, we can help.

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

Big or small, it’s backed by our one-year guarantee.

Why deal with it now?

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Upton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Why us?

  • Quality sealants from Arbo and Everbuild
  • White, clear, grey or coloured to suit, where the product allows
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Rated 4.9 stars on Google

Common questions in Upton

Can you help a landlord with a rental near Smallbrook Junction station?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.

Is external mastic in a coastal place like Upton any different?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures.

Are you an approved applicator?

Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Can I add another job to the visit?

Of course. Doing several areas at once is usually more efficient.

Can you match the colour of my brickwork?

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.

What do you need from me for a quote?

Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.

Do you guarantee your work?

Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.

Common problems we fix in Upton

Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.

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

  • Rigid filler in a joint that should flex
  • Weathered mastic that no longer stretches
  • Rain getting behind render or cladding at a joint
  • Panel joints letting water in

For an older house near a landmark such as Church of St. Michael and All Angels, an extension built onto an older house moves differently, and the joint between them takes the strain.

What your quote should include

  • Whether all the old sealant comes out first
  • How the surfaces are prepared before sealing
  • Who does the work, and how experienced they are
  • What happens if the job turns out different

How to choose a mastic man

How it works

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. Somewhere like Upton 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. Primer is applied wherever the sealant needs it.
  5. We gun in low-modulus sealant and tool it neatly.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access
  • Clear the area around the work

Upton buildings and the weather

Upton is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Haylands Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Smallbrook Junction station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Loose or hollow render, which needs re-rendering
  • Structural movement, which needs a surveyor or engineer

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

Surfaces we seal

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