Keeping the joints in good condition

So the new joints stay in good condition:

  • Ask before painting over external sealant
  • Make sure movement joints aren’t pointed over
  • Look over the joints every year, ideally after winter
  • Act on the first splits you see

Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.

Small splits are the time to act. At that stage it’s a simple cut out and reseal.

External mastic for homes and businesses in Mattingley

External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have rigid filler in a joint that should flex and joints with sealant missing in places, we can put it right.

In a village or hamlet like Mattingley, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

There’s a 12-month guarantee on every job, large or small.

Common problems we fix in Mattingley

UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.

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

  • Gaps where render, brick and frames meet
  • Moss and dirt in joints with no sealant left
  • Leaking joints around cladding and façade panels
  • Hard, crazed mastic that has stopped moving

Letting a property close to Hook station? Then split movement joints are easy to miss on a rental until damp shows inside.

Our hiring checklist

What happens on the day

When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Mattingley needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we look over the joints with you, agree which to renew and talk through access.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Let us know about parking restrictions
  • Let us know if you’ve seen damp or leaks

Advice

Mattingley questions

Do you work for landlords with property near Hook station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Can you do external mastic in Mattingley?

Yes. We work across London and the South East, and Mattingley is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.

Can new sealant go over the old?

No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

What colours does the sealant come in?

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 so it does not stand out.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can I add another job to the visit?

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

Do you work for hotels and businesses?

Yes, regularly. We can plan bigger jobs in stages.

How do I get a quote for external mastic in Mattingley?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

When something else is needed

In fairness, some problems need a different trade:

  • Cracks in the bricks or render themselves, away from the joints
  • Damp that is not coming from the joint
  • Loose or hollow render, which needs re-rendering

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

Where we work in Mattingley

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

What the job involves on each surface

Concrete and blockwork

Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.

Brickwork movement joints

People sometimes point up a brick movement joint by mistake. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.

Can I do it myself?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Why act early in Mattingley

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 pays to do it properly once. In a small place like Mattingley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

The cost depends on how much there is to do, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What external mastic looks like in Mattingley

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. With historic houses such as Stratfield Saye House (about 3.1 miles north-west) nearby, there’s older building stock in the area around Mattingley as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Homes close to Mattingley Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.
