Trusted external mastic in West Hythe

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

How we handle external mastic in West Hythe

As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. We work on joints between brick and frames, brickwork movement joints and render & cladding joints, and people most often call us about water getting into walls through failed joints and sealant that has lost its bond to the brick or render.

Around West Hythe, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.

All our work is covered by a 12-month guarantee.

What the job involves on each surface

Cladding and façade panels

If the façade has a specified sealant, that is what we use. Send us any details you have about the façade.

Render joints

Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.

Signs you need external mastic in West Hythe

The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.

The problems people generally mention when they call include:

  • Joints pointed up with cement by mistake
  • Panel joints letting water in
  • Plants rooting in failed movement joints
  • Cracked joints where brick meets render or frames

For landlords with property near Westenhanger station, split movement joints are easy to miss on a rental until damp shows inside.

FAQs for West Hythe

Do you work for landlords with property near Westenhanger station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Does living near the coast affect external mastic in West Hythe?

Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.

Where are you based?

Mr Mastic is based in Crawley. We cover West Hythe and the rest of Kent, along with the rest of our area.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Are you fully insured?

Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.

Do I have to be there?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.

Quotes for external mastic in West Hythe

For a quick quote, just ask. The main things that affect it are:

  • The product the joint needs

  • How many areas need sealing
  • Any working-time requirements on site

The cost reflects the work involved, not guesswork. That is why we ask about the job first.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Make sure movement joints are not pointed over
  • Keep water from gutters off the wall
  • Check external joints each spring
  • Avoid pressure-washing directly into sealant joints

Do not paint over the new sealant unless we’ve said the product is paintable. Paint can crack on a flexible joint.

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

West Hythe buildings and the weather

West Hythe is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.

For an older house near a landmark such as Church of St Stephen, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Lympne Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

The process

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like West Hythe, access is normally 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. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints
  • Where the joints are inside, avoid wetting them before we arrive
