Trusted external mastic in Thorpe Green

Should I try it myself first?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

External mastic in Thorpe Green

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. If you have joints where the bead has come unstuck and joints with sealant missing in places, we can put it right.

Around Thorpe Green, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.

Our work is backed for twelve months, in Thorpe Green and everywhere else we cover.

Landlord and commercial work in Thorpe Green

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Why act early in Thorpe Green

Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Thorpe Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Cracking across the wall rather than at a joint
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Failed render or damaged cladding panels

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

What external mastic looks like in Thorpe Green

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Botleys Mansion (about 2.1 miles south) nearby, there’s older building stock in the area around Thorpe Green as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

For landlords with property near Virginia Water station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you look after a building such as Thorpe CofE Aided Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What affects the cost of external mastic

We quote each job individually. These are the things that affect it:

  • The number of rooms or windows
  • The size of the job
  • The product the joint needs
  • When we can work, for business premises

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.

What to tell us for a quote

When you call or email, these details help:

  • Access, such as stairs, a lift or height
  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email
  • How many joints, rooms or windows are involved

If you are in Thorpe Green and need external mastic, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.

How the visit works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. In a small place like Thorpe Green, 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. 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

  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts

Advice

Looking after it afterwards

After the cure time, these simple habits help:

  • Ask before painting over external sealant
  • Make sure movement joints are not pointed over
  • Do not let climbing plants root in the sealant
  • Wash walls gently around the sealant

Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.

Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.

Thorpe Green questions

Will you come out to Thorpe Green?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do external mastic in Thorpe Green?

Yes. We work across London and the South East, and Thorpe Green is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

Will the new joint stand out?

There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.

How long before the joint can be used?

Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.

Why do you put foam in the joint first?

Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.

Which products do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

What information do you need?

Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.

Do you seal joints where cladding meets other materials?

Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides.
