External mastic in Ridgewood

For landlords and businesses

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.

About our external mastic in Ridgewood

Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Typical jobs include failed sealant between panels on a façade and movement joints filled with mortar instead of sealant, across concrete & block, copings & trims and joints between brick and frames.

Outbuildings, garages and conservatories around homes in places like Ridgewood add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.

The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Ridgewood questions

Is Ridgewood within the area you cover?

Yes, Ridgewood is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Uckfield station?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Where do you work from?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

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 reseal at that point.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

Is the work guaranteed?

Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few photos.

The process

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation for a typical job. A visit to Ridgewood is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  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.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about any previous sealing or DIY attempts
  • On commercial sites, let us know about site rules

Advice

External mastic in Ridgewood: local notes

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

In the older streets around St Saviour, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Harlands Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Surface by surface

Render joints

The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.

Concrete and blockwork

Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.

Common problems we fix in Ridgewood

Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.

Signs it’s time to call us include:

  • Sealant that has lost its bond to the brick or render
  • Moss and dirt in joints with no sealant left
  • Water getting into walls through failed joints
  • Panel joints letting water in

If you let a flat or house near Uckfield station, outside joints that have cracked can let damp into a rental, so check them between lets.

  • What the quote includes, VAT included or not
  • What insurance they hold
  • What happens if they find a problem under the old sealant

How to choose a mastic man

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Deal with leaking gutters that soak the joints below
  • Ask before painting over external sealant
  • Check external joints each spring
  • Wash walls gently around the sealant

Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.

If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Why deal with it now?

The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. In a smaller place like Ridgewood, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Read our cost guide and what customers say.

Should I try it myself first?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
