External mastic for Maresfield homes and businesses

External mastic for homes and businesses in Maresfield

Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have sealant pulling away from one side of the joint and panel joints letting water in, we can put it right, on brickwork movement joints, concrete & block and joints between brick and frames alike.

Older homes in small places like Maresfield may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.

Big or small, it’s backed by our one-year guarantee in Maresfield and across East Sussex.

DIY versus a professional finish

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 does not work out, we can still put it right.

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

What we do, step by step

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. Somewhere like Maresfield 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 start by walking round the building and agreeing the joints and the access.
  2. Every bit of old sealant and any mortar or debris is cut out.
  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.

When it isn’t the sealant

Before you book, it’s worth knowing the limits too:

Walls and rooflines in Maresfield

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Letting a property close to Uckfield station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. For an older house near a landmark such as The Parish Church of St Bartholomew, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Do you need external mastic in Maresfield?

Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.

Most people get in touch when they notice something like this:

  • Cracked joints where brick meets render or frames
  • Old sealant gone brittle and cracked
  • Movement joints with cracked, split or missing sealant
  • Rain getting behind render or cladding at a joint

If you look after a building such as Bonners CofE School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

FAQs for Maresfield

Is Maresfield in your area for external mastic?

Yes. Our work covers London and the South East, and Maresfield is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.

I let a flat near Uckfield station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all.

What is backing rod for?

We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back, so the joint can move.

Do you guarantee your work?

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

What should I tell you?

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

Can you work on commercial sites?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.

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 so it’s worth doing right. Older cottages and farmhouses around Maresfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • A 12-month guarantee on all work
  • Full insurance on every job
  • White, clear, grey or coloured to suit, where the product allows
  • Over 20 years’ experience

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Fix overflowing gutters above sealed joints
  • Show decorators and builders where the movement joints are
  • Check the sealant is paintable before painting near it
  • Keep high-pressure jets off the joints

Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.

If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
