Core Drilling and Vent Installation

 What is Core Drilling?

Core drilling is where we use a specialised tool to create a hole into the external wall of a building. We then fit a louvre vent to cover the hole on the inside and same on the outside (an exterior louvre vent). These vent covers are permanently open and designed to continually allow air to circulate.

Should you have vents in every room in your home?

All rooms in your home should have adequate vents, from the bathroom vent, to bedroom vent to living room and kitchen vents. Permavents fixed into your windows are not always enough to provide adequate ventilation.



What are the benefits of having Vents in your house?
  • Vents provide an adequate supply of fresh air for a comfortable and healthy environment for the occupants
  • They provide adequate air-flow for the safe operation of certain types of fuel-burning appliances
  • Installing Vents reduces the risk of condensation in an area in your home
  • Vents reduce the accumulation of radon and other dangerous gases in the home


What is Mould Solutions vent installation process?

It is important to note that the installation of a drilled wall vent should not be attempted without the requisite skills and equipment. A properly constructed work platform is hugely important. The reason for this is because the force generated by a core drill can easily overpower the user and lead to serious injury.

  • Mould Solutions system drills from the inside out. We create very little or no dust during the process.
  • We use a dry drilling system
  • Typically, a hole between 112mm – 150mm in diameter is drilled using a core drill to the exterior wall. (size dependant on requirement)
  • We then install a uPVC pipe insert inside the hole to the cavity.
  • Louvre vent covers (permanently open) are fitted and secured to the wall both internally and externally.

How Can I Prevent Condensation?

Condensation can be a problem in both old and new homes, but what causes it and what can be done to prevent it?

What is Condensation?

The air around us naturally contains moisture. The air temperature determines how much moisture it can hold, and warm air contains more moisture than cold air.

When moist warm air comes into contact with either air or a surface which is colder than it is, the warm air cannot retain the same amount of moisture as it did and the water is released either onto the colder surface or into the air, resulting in condensation. This then leads to mould formation

What Causes Condensation?

Everyday activities such as washing cooking, drying clothes and even breathing produce excess moisture. Air can only hold so much moisture, so when it contains too much moisture it reaches ‘saturation point’.  This is when the moisture turns back into water and condensation occurs.

How Can I Treat Condensation?


In order to prevent condensation there are three main areas to look at. Ventilation, Insulation and humidity

You can control the humidity levels in your home and in particular in your kitchen and bathroom through use of an extractor fan. Keeping the doors to these rooms shut while the extractor fan is on also helps.

Ensure there is adequate ventilation throughout your home. Newly built properties tend to be airtight which can encourage condensation, so it is vital to ensure that there are vents installed within your home. Learn more about ventilation and the associated services we provide here

I’ve A Water Leak In My House. Should I Be Worried About Mould

Water Leaks And Mould

Finding a water leak in your house is never something you want to be faced with. In addition to this, a failure to find the source of a leak in a property can lead to huge damage if left undetected. Fortunately, finding hidden leaks is something we specialise in regardless of whether they are of a structural nature or located within the water system itself.

Leaks & Mould
Leaks & Mould

How Fast Does Mold Grow After A Leak?

Mold (Mould) and Mildew will develop within 24-48 hours of water exposure. Unfortunately, it will continue to grow until steps are taken to detect and eliminate the source of the leak, and deal effectively with the problem. You can find out more about mould in your property here.

How Can I Find A Leak In My House?

Leaks often don’t present themselves as a straightforward obvious flow of water. They can be concealed within a floor for example due to a break in a heating pipe. This example could manifest itself as a malfunctioning boiler whereas a slow leak within a wall can result in mould or mildew forming in that area. However your leak appears, our experts are equipped to find it. You may notice grouting in tiles breaking or bulging.  This is a typical sign of water build up behind the tiles and could be from a leak.

Should I Buy A House With Mould?

Should I Buy A House With Mould?

Looking for the perfect house and think you have found it only to discover that there is something sinister inhabiting a few of the rooms – Mould!

Appearances aren’t always what they seem!

Unfortunately, initial appearances aren’t always as they seem and what may look like a small issue seems to multiply and spread no matter what you do to attempt to keep it at bay.

Usually with mould comes that damp musty smell. You can see the mould, you can smell the mould, but it can be difficult to figure out what is causing it. Things are even trickier when it’s a house that you are thinking of buying. You don’t know about the history of the property or its owners. Is it well ventilated?…are there any other underlying issues? The first thing you should do is get a survey of the property. This should identify any major structural issues.

You also need to look at the bigger picture before you make any major decisions. There are now numerous questions that need to be asked to determine what is causing the mould and how to stop it. The mould itself whilst unsightly isn’t the main problem…it’s a symptom. Mould can only grow in an environment with excess moisture. The mould itself will need to be addressed and remediated eventually, but until the cause is found there isn’t much point as it will continue to return.

Is It Ok To Buy A House With A Small Patch Of Mould?

This small patch of mould may seem insignificant. The problem with this however, is that there may be a significant amount of mould growth on the surface that you cannot see – e.g. under the floorboards or inside cavity walls.

What Are The Causes Of Mould In A House?

Mould is a symptom of excess moisture in a property. This could indicate a leak or a damp problem.

Plumbing leaks or leaky gutters are common causes of mould growth.

Condensation is also one of the biggest causes of mould growth. It happens when water collects as drops on a cold surface when humid air is in contact with it. It is very common on windows in Winter and can result in patches of mould on a window.

Mould is also common behind large objects such as wardrobes and beds…typically areas which do not get much ventilation and on north-facing walls. Read more on this here

What Should You Do If You Cannot See Any Obvious Signs Of A Leak Or Build Up Of Condensation? Should You Go Ahead And Buy The Property?

This is where a mould inspection can help. You can book yours here.

A mould inspection will identify areas where there are high levels of moisture. It should provide you with the cause of the problem so you know what needs to be fixed before the actual mould itself is remediated. Remember, mould remediation is ineffective unless the cause of the moisture is dealt with first.

Happy House Hunting!

Before and after images of mould on a bathroom ceiling

We all like a before and after image and here are some mould removal examples.

We treated a bathroom  which, as you can see is quite badly infected with mould.

Mould Solutions don’t just treat the area affected, we treat the entire room. This is because mould spores are invisible to the naked eye, but are typically present on other surfaces in the room.

We always advise not to wipe or attempt to clean mould yourself as it becomes airbourne and it spreads, this is what Mould loves to do !

How badly fitted insulation can cause mould to form

Who would have thought that badly fitted insulation could lead to mould forming in a room below?

In this particular case you can see that the insulation in the attic space doesn’t reach the corner of the eaves properly and this in turn has caused a cold spot which has resulted in mould forming in the room below. As we all tend to use our attic space for storage, we can inadvertently moved loose insulation unknown to ourselves while putting things into and taking things out of our attic.
Insulating your attic effectively will keep warm air in the main area of the house and your attic will remain cold as a result. As long as it is dry up there, this shouldn’t cause any issues if you’re only going up every now and then to grab a box.

Problems arise when moisture gets into the attic area and as you can see in this example it is exactly what happened.

Damp can set in and lead to mould, which can be tricky to get rid of.

The idea of insulation is to seal the inside of your home so that there are no cold spots where heat can escape to, which turns into a spot for moisture to form and create condensation and cause mould to form.

In this case, Mould Solutions treated the existing mould in the property and repaired the loose insulation in the attic.

Wardrobes and the problems with mould

How often do we check behind our wardrobes? Do we ever think there may be mould behind them? Well read on to discover wardrobes and the problems with mould.

I would say almost never!

Don’t we have enough to do?

We get so many queries with “there is a musty smell” and I can’t figure out from where. Lets look at a room where we recently investigated following a call from a concerned client.

We removed a wardrobe door, and internal shelving and here is what we discovered behind…

Mould on external wall behind a built in wardrobe

Now, you eagle eyed folk may notice a vent on the wall and wonder why mould still formed. It turns out the vent was completely covered with the curtains so it was effectively, ineffective.

Mould Solutions were called in to carry out our treatment process.

We start this by spraying the area with our specialised product, we leave it to do its work, which is to kill the mould.

We then wash down the area on completion and in this case, as the mould was quite bad, we repeated this process a couple of times.

Take a look at the end result!

Mould eradicated following mould removal treatment

As you can see the mould has now been eradicated, killed and gone.

We suggested to our client to change her curtains width so as to make the vent hole do as it is meant to do, ventilate. Keep an eye on external walls, and cold spots, we suggest at least an annual spring clean look in corners and wipe down external walls for any dust or indeed damp spots you may discover.

If you do have vents in your rooms it is important to check they are not obstructed with any furnishings or furniture and check that they are not blocked up internally.

Effects of damp and mould on your body and health – and what you can do about it!

With the weather becoming colder and wetter, damp and mould might potentially be on the rise in your home – but there are ways to tackle and prevent it.

Firstly find the root cause, dont’ simply clean it yourself hoping it will keep it at bay. By wiping visible mould away you are releasing spores into the air, and therefore spreading it.

If left untreated, damp and mould can affect your health. This is especially true if you are elderly or have any underlying conditions. There are ways to find the exact cause of the damp, clean up the mould and minimise the risk of it returning.

The end result –  a healthier home and happier family.

can mould affect your health
Damp or mould in your home can lead to respiratory problems

So, what is Mould?

Mould is a fungus which can be found indoors or outdoors. It loves living in our homes, as they provide the perfect conditions for it to thrive – warmth, moisture and food in the form of carpet, wood, paper, dust and dirt. Unless the issue is dealt with and removed, it will continue to grow.


Can it affect my health?

If you have a damp/mould issue in your home, you are more likely to already have or, to develop respiratory problems. It can also have an adverse affect on the immune system.  This is bad news for anyone’s lungs, but it is very dangerous for vulnerable people with an underlying condition like asthma.

Risk Groups include the following:

  • The elderly
  • Babies and young children
  • Those with existing skin conditions e.g. eczema
  • People with weak immune systems
  • Individuals with respiratory problems like asthma and allergies

I’m not in one of the high risk groups. Can Mould affect my health?

Mould produces irritants, allergens and sometimes toxic substances. Touching or inhaling mould spores may result in an allergic reaction, like sneezing, red eyes, a runny nose and a skin rash.

Moisture causes mould & damp
Mould and damp are caused by an excess of moisture in the air

What causes damp and Mould?

Mould and damp are caused by an excess of moisture in the air. This can be caused by leaks in pipes, rising damp or rain seeping in due to damage to roof tiles or around window frames.  Key areas for leaks are the kitchen & bathroom.

A newly-built home may be damp if the water used when building it is still drying out – for example the plaster on the walls. Some new builds are also so air tight that they do not allow fresh air to circulate around the home which results in damp & mould.

If you have mould or damp, it’s important to find out why you have excess moisture within your home.

Open windows every morning to allow fresh air to circulate
Open windows every morning to allow fresh air to circulate


You can help prevent damp/mould growth by:

  • Avoid drying washing inside
  • Open windows every morning to allow fresh air to circulate
  • Make sure your home is well insulated
  • Heat your home adequately
  • Put lids on saucepans while cooking and use sufficient extraction
  • When cooking, showering or bathing open the window, put the fan on and close the door of the room you’re in

When you know what’s causing the damp, take steps to limit the amount of moisture in the air and make sure your home is repaired. Tackling severe damp and mould problems may require an expert to assess your property and pinpoint exact causes.
