About our external mastic in Westbere

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. If you have movement joints with cracked, split or missing sealant and failed sealant between panels on a façade, we can help.

Somewhere as small as Westbere, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.

All of our work is guaranteed for twelve months.

What we can’t put right

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Subsidence or other structural problems
  • Cracking across the wall rather than at a joint
  • Damp that is not coming from the joint

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

What we seal

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

Landlords, agents and businesses in Westbere

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

How it works

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. Somewhere like Westbere needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, the joints are inspected and the access agreed.
  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.

Before we arrive

  • Tell us if parking is tricky
  • Mention any leaks or damp you’ve noticed
  • Let us know about stairs, lifts or work at height

Advice

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Leave the joints unpainted unless we’ve said otherwise
  • Have failed joints looked at early
  • Clear growth from the base of walls and joints
  • Show decorators and builders where the movement joints are

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.

Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

What we’re called out for in Westbere

Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.

The problems people normally mention when they call are:

  • Plants rooting in failed movement joints
  • Water getting into walls through failed joints
  • Movement joints filled with mortar instead of sealant
  • Failed seals between different materials

Schools such as Spires Academy are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Questions to ask before you book

  • Which colour the sealant will be
  • Who does the work, and how experienced they are
  • How the surfaces are prepared before sealing
  • What guarantee comes with the work

How to choose a mastic man

Westbere: your questions answered

Do you cover smaller places like Westbere?

Yes. Westbere is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

I let a flat near Sturry 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’ll give you a fixed price before work begins.

Are you insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

What does external mastic cost?

Size, access and the old material all affect the cost. Call for a quick quote.

How long does the job take?

A typical job takes a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. We will confirm how long when we quote.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Can new sealant go over the old?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Different surfaces, different methods

Render joints

Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.

Copings and trims

Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.

Quotes for external mastic in Westbere

Jobs vary more than people expect. The main factors:

  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove
  • The size of the job
  • Access and height

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we need to know

When you contact us, these details help:

  • If someone has resealed it before
  • How we’d reach the joints
  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business

We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or email us.

Westbere buildings and the weather

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.

Letting a property close to Sturry station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of All Saints include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
