External mastic in Pusey

About our external mastic in Pusey

External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. Common call-outs are for damp patches traced to an open external joint and old sealant gone brittle and cracked, across copings & trims, concrete & block and joints between brick and frames.

Older homes in small places like Pusey may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.

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.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, 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.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

What the job involves on each surface

Copings and trims

A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.

Cladding and façade panels

Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. The sealant is chosen with that in mind.

Leave it or put it right?

The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the damage spreads beyond the joint. In a small place like Pusey, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Pusey questions

Do you cover smaller places like Pusey?

Yes. Pusey 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.

Is Pusey in your area for external mastic?

Yes. Our work covers London and the South East, and Pusey is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

What is a movement joint?

Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Can you work on commercial sites?

Yes, regularly. Larger jobs can be planned room by room or area by area.

Can you match the colour of my brickwork?

We aim for a joint that suits the wall rather than one that jumps out. We will talk through colour options before work begins, matched as closely as the range allows.

I’m a tenant. Can you help?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

When will the joints need doing again?

It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away and have them redone then.

What happens on the day

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Pusey, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by walking round the building and agreeing the joints and the access.
  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. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Before we arrive

  • Tell us if parking is tricky
  • Clear items away from the joints we’re working on
  • Try not to wet indoor joints just before the visit

Related advice

When to call us in Pusey

The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.

Common reasons people contact us are:

  • Movement joints with cracked, split or missing sealant
  • Failed sealant between panels on a façade
  • Water getting into walls through failed joints
  • Weathered mastic that no longer stretches

If you look after a building such as Buckland Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What to look for in a quote

  • How much experience the applicator has
  • What happens if the job turns out different
  • Whether they seal over old material or remove it
  • When the joint can take water or movement

How to choose a mastic man

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Never let anyone fill a movement joint with mortar
  • Ask before painting over external sealant
  • Check external joints each spring
  • Get split or bare joints resealed while the damage is small

Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.

Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.

Pusey buildings and the weather

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Longworth House (about 2.4 miles north-east) are a reminder that the area around Pusey 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.

In the older streets around Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.
