External mastic for Lane End homes and businesses

Looking after it afterwards

So the new joints stay in good condition:

  • Show decorators and builders where the movement joints are
  • Deal with leaking gutters that soak the joints below
  • Check external joints each spring
  • Make sure movement joints are not pointed over

Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.

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

External mastic for homes and businesses in Lane End

On houses, flats and commercial buildings across Lane End, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. Typical jobs include old sealant gone brittle and cracked and failed seals between different materials, on render & cladding joints, façade panels and joints between brick and frames.

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

Whatever the size of the job, it’s backed by our one-year guarantee in Lane End and across Hampshire.

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Your questions about external mastic in Lane End

Do you cover smaller places like Lane End?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is there a guarantee on external mastic in Lane End?

All our work, in Lane End and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Can I add another job to the visit?

Yes, we can. Several rooms, windows or areas can go on one quote.

How do I get a quote for external mastic in Lane End?

Size, access and the old material all affect the cost. Ask us for a quote.

How long before the joint can be used?

That depends on the sealant used, so follow the cure time we give you when we finish.

Can new sealant go over the old?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

When will the joints need doing again?

That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Different surfaces, different methods

Render joints

Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Brickwork movement joints

Vertical joints in long brick walls let the brickwork expand without cracking. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.

What affects the cost of external mastic

The price is agreed before any work begins. It’s based on:

  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows
  • When we can work, for business premises
  • The amount of work

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • Access, such as stairs, a lift or height
  • The rough size of the job
  • Whether it’s a home or a business
  • Any previous sealing or DIY work

For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved before giving you a price.

What external mastic looks like in Lane End

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. With historic houses such as Hinton Ampner House (about 2.8 miles north-east) nearby, there’s older building stock in the area around Lane End as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

In and around Lane End, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. Hinton Ampner House, about 2.8 miles north-east, is one of the historic houses in the wider area around Lane End.

What happens on the day

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Lane End, the journey is planned in advance: 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.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Keep children and pets away from the work area
  • Mention any tricky access

Why deal with it now?

It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. In a small place like Lane End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
