External mastic in Middleton

External mastic in Middleton, done properly

Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Typical jobs include sealant pulling away from one side of the joint and failed sealant between panels on a façade, across façade panels, joints between brick and frames and render & cladding joints.

In a smaller place like Middleton, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Leave it or put it right?

Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In an older home around Middleton, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Outside joints around Middleton

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Linford Manor (about 3.1 miles north-west) nearby, there’s older building stock in the area around Middleton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

For landlords with property near Bow Brickhill station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Middleton Primary School, larger buildings have long runs of movement joint that eventually need resealing.

FAQs for Middleton

Do you cover Middleton for external mastic?

Yes. Our work covers London and the South East, and Middleton is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

Is Middleton within the area you cover?

Yes, Middleton is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us and we are fully insured.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

How often do external joints need resealing?

It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

Is there a guarantee?

Yes, always. There’s a 12-month guarantee on every job, wherever you are.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

How it works

When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work generally takes a few hours to a few days, depending on the length of joint and the access. Parking around Middleton is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
  • Let us know about stairs, lifts or work at height

Advice

What affects the cost of external mastic

Every job gets its own quote. These are the things that affect it:

  • Whether the work is at height
  • Mould in or behind the old joints
  • Working hours on commercial sites
  • How many areas need sealing

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • The type of property
  • Photos by email, if that is easy
  • How we’d reach the joints
  • Where the job is, and your postcode

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Point out the joints to other trades
  • Check external joints each spring
  • Fix overflowing gutters above sealed joints
  • Keep high-pressure jets off the joints

If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

When something else is needed

A few problems are outside what sealant work can do:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Loose or hollow render, which needs re-rendering

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Surfaces we seal

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