External mastic near East Stourmouth

East Stourmouth: your questions answered

Do you cover East Stourmouth for external mastic?

Yes, East Stourmouth is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.

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

Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.

Will the new joint stand out?

The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.

Do you work at height?

It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we will confirm the access.

What does external mastic cost?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Do you remove the old sealant?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

What do you need from me for a quote?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.

About our external mastic in East Stourmouth

A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you’re dealing with weathered mastic that no longer stretches and failed seals between different materials, we can help.

Somewhere as small as East Stourmouth, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.

You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What sealant work can’t fix

We’d rather tell you now than do work that will not last, so these are the limits:

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Movement that is more than a sealant joint can take
  • Damp that is not coming from the joint

If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

What we seal

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

Why act early in East Stourmouth

Running new sealant over the old bead rarely lasts. The new layer cannot bond properly to old, weathered material, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like East Stourmouth, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Why choose Mr Mastic in East Stourmouth

  • Quality sealants from Arbo and Everbuild
  • An ARBOMaster approved applicator
  • Sealant colour chosen to suit
  • Old sealant always removed completely

East Stourmouth buildings and the weather

Historic houses like Quex Park (about 4.7 miles north-east) are a reminder that the area around East Stourmouth has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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 Minster station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

How it works

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like East Stourmouth, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. We prime the faces where required.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

  • Let us know about stairs, lifts or work at height

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What we’re called out for in East Stourmouth

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.

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

  • Joints pointed up with cement by mistake
  • Sealant that has lost its bond to the brick or render
  • Moss and dirt in joints with no sealant left
  • Gaps where render, brick and frames meet

In the older streets around All Saints Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What your quote should include

  • Whether all the old sealant comes out first
  • Are they insured?
  • What the cure time is
  • The length of the guarantee

Our hiring checklist

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Point out the joints to other trades
  • Keep soil, plants and ivy away from the joints
  • Check external joints each spring
  • Get split or bare joints resealed while the damage is small

Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.

An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
