Key Takeaways:

  • Understanding Causes of Cold Walls: Inadequate insulation, dampness, and structural issues commonly contribute to cold walls. Insufficient insulation allows warm air to escape, particularly in cavity walls without proper insulation. 
  • Ways to Warm Up Walls: Improving insulation is essential to alleviate the discomfort of cold walls. Enhancing sound insulation through an initial investment can offer long-term energy efficiency benefits. Cavity wall insulation is a cost-effective option to fill gaps and reduce heat loss. 
  • Preventing Condensation on Cold Walls: Condensation on cold walls can lead to moisture-related problems. Improving ventilation, using extractor fans in high-humidity areas like kitchens and bathrooms, and considering a dehumidifier can help reduce condensation. 


In winter, cold walls can be an uncomfortable and frustrating source of feelings. If this has ever happened to you in your house, you might wonder why it feels so cold against the walls. Several sources claim inadequate insulation is the leading cause of rigid walls, especially in older homes with solid walls. 

Roughly 35% of heat loss occurs through walls and gaps, contributing to the incredible sensation on the walls. Finding methods to improve the comfort of your living area may be made more accessible by being aware of these issues. You may make your home cosier and warmer by employing enough ventilation, handling insulation problems, and putting reasonable solutions in place.

Why Does My House Have Cold Walls?

We understand that dealing with cold walls in your house can be uncomfortable and may indicate underlying issues. Comprehending why freezing walls is essential to effectively address the problem and create a more comfortable living environment. Here are some common causes to consider:

Inadequate Insulation: 

Insufficient insulation is often a significant factor contributing to cold walls. Warm air can escape if your internal walls lack proper insulation, leaving them unconscious. This issue is particularly problematic if you have cavity walls without sufficient insulation.

Dampness and Structural Issues: 

Dampness on cold walls can worsen the problem. Cracks in the walls or damaged gutters are structural and architectural issues that let cold air in and allow moisture to seep into the walls. More severe problems like wood rot and black mould might result from chilly walls and humidity.

To address these issues effectively, it is crucial to first treat any existing damp problems before tackling the issue of cold walls. Identifying the cause of dampness and seeking assistance from a wet specialist will ensure proper remediation.

Taking proactive steps to improve insulation is also essential. Consider adding or upgrading insulation materials to prevent warm air from escaping and keep your walls warmer. Resolving structural flaws will assist in stopping cold air intrusion and other moisture difficulties. Examples of these problems include cracked or damaged gutters.

An environment that is more comfortable and energy-efficient can be achieved by identifying the underlying causes of chilly walls and taking systematic steps to solve them. Our team of professionals is here to help you identify the problems and offer workable fixes.

How Can You Warm Up the Walls?

If you want to warm up your walls and they feel cold to the touch, there are several solutions to consider. Here are some options that can help make warm surfaces on your walls feel warmer:

Improve Insulation: 

Sound insulation is crucial for your energy bills and preventing wall heat loss. While it may require an initial investment, improving insulation can provide long-term energy efficiency and comfort benefits. Adding or upgrading insulation materials can retain warmth and warm your walls.

Cavity Wall Insulation: 

It’s easy and affordable to fill any cavity walls in your property with insulation. Cavity partition insulation holds the capability to markedly improve the warmth of your partitions by diminishing heat depletion. Discussion with an expert is advisable to ascertain the appropriateness of cavity enclosure insulation for your particular area.

Check Existing Insulation: 

If your walls are still cold even though you have cavity wall insulation, there can be a problem with the insulation itself. It can be broken, installed incorrectly, or insufficient for your requirements. Speaking with an expert might assist in locating and resolving any insulation problems.

Warming up your walls involves raising their temperature and halting heat loss. By enhancing the insulation in your residence, you might improve its comfort and energy efficiency.

How to Prevent Condensation on Cold Walls

You may take further precautions to avoid condensation, which can result in wetness and other problems when it forms on chilly walls and surfaces. What you can do is as follows:

Improve Ventilation: 

Improving ventilation is essential for lowering condensation in rooms with chilly walls. You can aid in keeping the walls dry by clearing the impacted regions of warm, humid air. Improved airflow and less condensation can be achieved by opening windows and doors, particularly in high-humidity spaces like kitchens and bathrooms.

Utilise Extractor Fans: 

Use the fans in your kitchen and bathroom if you have them for cooking or bathing. By eliminating warm air, these fans lessen the possibility that condensation may build up on the walls.

Consider a Dehumidifier: 

A moisture remover can be employed to eliminate additional humidity from the atmosphere appropriately. A dehumidifier, albeit not a long-term resolution, can aid in diminishing condensation by substituting hot, moist air with arid, pure air.

Insulate Pipes: 

Insulating pipes can prevent them from becoming cold and causing condensation. Wrapping exposed pipes with insulation can minimise condensation formation and potential water damage.

While addressing insulation issues and improving ventilation are critical long-term solutions, implementing these additional measures can help combat condensation on cold walls and create a healthier indoor environment.
