Insulation Removal

Using our specialised equipment, MakeWarm can extract defective cavity wall insulation to domestic and commercial properties causing little disturbance to the fabric of the building or its occupants.

HOW CAN WE HELP?

It shouldn’t come as to much of a surprise that here at MakeWarm Ltd, we specialise in Cavity Wall Insulation Removal across England and Wales for those properties that are suffering from insulation problems, such as mould, rot and/or damp walls.

We offer a cost-effective way to remove and extract faulty cavity wall insulation using some of the latest insulation machinery currently available, removing retro fitted cavity wall insulation when it simply isn’t up to the task of insulating your home any longer. We think that everyone deserves to live comfortably within their own home and our removal service can help you swiftly achieve this.

Some of the most common materials we frequently find ourselves removing from a home’s cavity walls include expanded polystyrene, loose and/or bonded Urea Formaldehyde Insulation, Rockwool Mineral Fibre and White Wool Glass Mineral Fibre to name a few. If any of these were not sufficiently installed in the past, your home could be one of the many suffering from inadequate thermal retention – That’s where we come in!

Why remove insulation?

As much of a hassle removing your home’s existing cavity wall insulation may seem, if left unchecked incorrectly installed cavity wall insulation can lead to expensive problems. It can result in damp penetration and mould growth, leaving your home more at risk than it initially was prior to the introduction of insulation.

The UK began constructing properties with cavity walls from 1920, and two decades later it became standard industry practice. But wrongly installed cavity wall insulation can lead to an array of problems. Penetrating Dampness can lead to crumbling salt contaminated plaster and later to more serious structural and timber decay such as wet / dry rot and insect attack to structural timbers.

In order to prevent these instances from occurring, removing your home’s inadequate insulation materials is the most cost-effective and time-saving solution and with our team’s knowledge and skill we can extract any defective insulation without causing too much disturbance or hassle.

Wall insulation issues

Not all properties are suitable for Cavity wall insulation and extraction may be necessary for a number of reasons, including:

WET INSULATION

  • Water penetration from wind driven rain
  • Mortar or render in a poor state of repair
  • Water tracking across rubble / debris, and also snot (lumps of mortar) on wall ties
  • Insulation slumped; due to absorbing water
  • Flood damage

VOIDS IN THE CAVITY

  • Insulation not blown in the cavity at the right density
  • Machine is shut off too early
  • Incorrect drill pattern used

Insulation deterioration

Signs that your cavity wall insulation is deteriorating can be as little as a small draught that regularly occurs in the same spot to the literal appearance of mould emerging on your wall’s exterior. When looking in the cavity wall itself, these are physical warnings that the Urea formaldehyde foam has started to shrink, thus being prone to degrading over time.

Insulation removal process

HOW WE REMOVE CAVITY WALL INSULATION:

  1. Cut a brick out at the bottom of the property using an arbortech allsaw. This specialist tool allows us to save the original bricks so we can put them back in when we are done
  2.  

  3. Drill the existing insulation injection holes out but only using a 14mm hole not the standard 22mm. (Additional holes may be required above windows as this is a trap area for the insulation)…

Cavity insulation removal process

  1. Cut a brick out at the bottom of the property using an Arbortech allsaw. This specialist tool allows us to save the original bricks so we can put them back in when we are done.
  2. Drill the existing insulation injection holes out but only using a 14mm hole not the standard 22mm. (Additional holes may be required above windows as this is a trap area for the insulation).
  3. An extra row, 3 bricks above the damp proof course (D.P.C) is also needed to ensure all cavity wall fill is pushed towards – and sucked out by – the hoover, ensuring no insulation remains above the D.P.C.
  4. Starting at the first hole, closest to the industrial Hoover (where the brick was removed), we use compressed air to force the insulation towards the hoover. This causes a gap in the insulation which allows the material to be sucked out. We then move a level above, to force the next section to the gap below and continue to repeat the process, forcing all the insulation downwards and out via our extraction hoover.
  5. The extracted material is bagged on-site and removed under a waste carrier’s license.
  6. The property is then checked with a borescope to make sure the cavity wall insulation is removed. A specialist attachment can also be used to link the borescope to an iPhone. This allows us to take photos and videos of the inside of the cavity, which then allows our customers to properly inspect our work, and ensure all insulation is removed for themselves. These pictures and videos can be retained for you records.
  7. All flues, chimneys and gas vents are checked by a competent & accredited person.
