How we handle external mastic in Seale

Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We work on façade panels, joints between brick and frames and render & cladding joints, and common reasons people get in touch are leaking joints around cladding and façade panels and moss and dirt in joints with no sealant left.

Older homes in small places like Seale may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.

All of our work is guaranteed for twelve months.

Common questions in Seale

Do you cover Seale for external mastic?

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

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

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.

Can you seal joints between render and window frames?

Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.

When will the joints need doing again?

There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Every job carries our one-year guarantee.

Is it OK to fill a movement joint with cement?

No. Rigid materials cannot move with the wall and the joint fails. If it has already been filled, we can usually cut it out and reseal it.

What’s an expansion joint in brickwork?

A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.

What colours does the sealant come in?

The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.

Are you insured?

Yes. Mr Mastic is fully insured.

When to call us in Seale

Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.

Look out for these signs:

  • Moss and dirt in joints with no sealant left
  • Cracked joints where brick meets render or frames
  • Failed sealant between panels on a façade
  • Damp patches traced to an open external joint

For site and facilities teams at buildings such as St Paul's CofE Infant School & Nursery, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What your quote should include

  • Is the old sealant removed completely?
  • How long to leave it before use
  • Which sealant they’ll use, and why
  • What guarantee comes with the work

10 questions to ask before you book

Why it’s worth doing now in Seale

The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Seale, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What happens on the day

When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Seale, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. We apply the sealant, tool it and check the whole run.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions

When it is not the sealant

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Subsidence or other structural problems
  • Failed render or damaged cladding panels
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course

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

Where we work in Seale

How we quote for external mastic

The quote reflects the job in front of us. We look at:

  • Which sealant suits the joint
  • How easy the joints are to reach
  • Mould in or behind the old joints
  • The old material and how stubborn it is

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • Whether it has been sealed before
  • Where the property is
  • The problem you’ve noticed
  • Access, such as stairs, a lift or height

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Wash walls gently around the sealant
  • Fix overflowing gutters above sealed joints
  • Check the sealant is paintable before painting near it
  • Tell anyone working on the walls about the movement joints

Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.

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

How the job changes by surface

Render joints

Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.

Brickwork movement joints

People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly where it can be done safely.

What external mastic looks like in Seale

Historic houses like Wanborough Manor (about 2.4 miles east) are a reminder that the area around Seale 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Homes close to Church of St Laurence include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Ash station, outside joints that have cracked can let damp into a rental, so check them between lets.
