He was very knowledgeable in the field, and walked us through the solutions we need to take. Our treatment was carried out by Craig, who took special care of all household items, whilst carrying out the treatment. Craig made sure to explain the best methods of cleaning the treatment. Would highly recommend! Thank youPosted on Leah Warner-TedaldiTrustindex verifies that the original source of the review is Google. We had Kai and Sam come to do isotherm insulation on our walls. They were great, really upbeat and friendly. They worked really hard and left the place so tidy. The work looks good so far! Review is done on the day of completion Update: we had a lot of trouble with this company in the end. The plastering work ended up needing to be redone. It took 6 weeks for it to be redone and we were left with a completely unusable room and really bad communication. There were so many times when I rang through to the switchboard and escalated matters for nothing to happen. We felt totally helpless and stranded. I have since tried to get through to their complaints team to no avail. We had the isotherm sheeting fixed which was then skimmed over the top. Once this had set you could quite easily push it in with your finger, denting it (see pic of finger dents). The company surveyor (who we asked to be sent round) said that this was expected and how the isotherm works (I would not recommend!) Luckily they sent a plasterer round to fix it, and he said the whole thing (isotherm and all) needed to be redone, and he redid it all. It now looks really good and doesn’t dent with your finger. TBH I wouldn’t recommend this company, I found them impossible to get in touch with and just gatekept at a switchboard and left us in a really vulnerable position and took 6 weeks to fix it.Posted on Monika NiebojTrustindex verifies that the original source of the review is Google. Larry has arrived today with lots of helpful information, been very polite and understanding. Definitely recommended :)Posted on Amanda WilliamsTrustindex verifies that the original source of the review is Google.

Had John and Ron at my house this morning fitting a new damp course. They were both friendly and professional. They turned up at my property on time, did a very neat job, explained everything that they were going to do and cleaned up after they had finished.Posted on James WaltonTrustindex verifies that the original source of the review is Google.

What is Condensation in the Loft?
Condensation in the loft occurs when warm air is absorbed by traditional insulation such as fibreglass.
This warm air comes into contact with cold air in the loft. This is known as the dew point, and this is where condensation occurs.

Free Loft Insulation Assessment
A loft insulation assessment helps prevent condensation by evaluating airflow, insulation quality, and moisture levels. Inadequate insulation can cause warm air to meet cold surfaces, resulting in damp and mould. Our experts assess both insulation and airflow to recommend solutions, ensuring a dry, energy-efficient loft with long-term protection.
We cover the Midlands and the North West of England.
How Can Loft Condensation Be Stopped?
To address damp and condensation in your loft, it’s essential to take proactive measures. Ensure that your loft has proper airflow to allow moisture to escape and prevent stagnant air from accumulating.
Adequate insulation, such as radiant reflective barrier, is also vital to maintain stable temperatures and prevent condensation build-up.
Radiant Reflective Barrier Insulation for Loft Condensation
Radiant reflective barrier insulation helps reduce loft condensation by regulating temperature differences between warm air and cold surfaces. It reflects heat in summer and retains warmth in winter, preventing moisture build-up.
This reduces the risk of damp and mould. When combined with proper airflow, it provides an effective, energy-efficient solution for controlling loft condensation.
Radiant reflective barrier insulation complies with building regulations.
What to Expect From Our FREE Loft Insulation Assessment
One of our experienced surveyors will assess the efficiency of your current insulation, checking for areas where heat may be lost, such as your walls. They’ll inspect for damp, as it can promote heat loss, and provide general energy-saving tips.
Using a range of tools and digital instruments, our surveyors ensure accurate assessments and will fully explain any issues, potential risks, and solutions. We offer a FREE Loft Assessment Inspection for all property owners.
Frequently Asked Questions
What causes condensation in a loft?
Loft condensation usually happens when warm moist air from inside the home rises into a cold loft space. When this air meets colder surfaces such as roof felt or timbers, moisture forms as condensation. Common causes include poor ventilation, blocked eaves, inadequate insulation, and everyday household moisture from cooking, bathing, and drying clothes indoors. At Home Energy Save GB, we often identify several contributing factors during our free condensation surveys.
Is loft condensation a serious problem?
Loft condensation should never be ignored as it can lead to mould growth, timber decay, and reduced insulation performance over time. While it may start as a seasonal issue, persistent moisture can damage roof structures and increase heating costs. Home Energy Save GB regularly sees lofts where condensation has been present for years without the homeowner realising. A free condensation survey helps assess the severity and prevent long term damage.
Is loft condensation caused by a roof leak?
Not always. Loft condensation is often mistaken for a roof leak, but the two are very different. Condensation usually appears evenly across surfaces and is worse in cold weather, while leaks tend to be localised. During a free condensation survey, Home Energy Save GB carefully checks roofing materials, ventilation, and moisture patterns to ensure the correct issue is identified and treated properly.
Can loft condensation cause mould?
Loft condensation can lead to mould growth on timbers, insulation, and stored items if moisture levels remain high. Mould thrives in damp environments and can spread over time. While loft mould is often hidden, it can affect air quality and structural materials. Home Energy Save GB regularly treats lofts where condensation has caused mould, using targeted ventilation and moisture control solutions after a free survey.
How quickly should loft condensation be dealt with?
Loft condensation should be addressed as soon as it is identified, especially if moisture is persistent. Delaying action increases the risk of mould, timber damage, and insulation issues. Home Energy Save GB recommends booking a free condensation survey at the first signs of dampness to prevent further deterioration and avoid higher repair costs.
Do you offer free surveys for loft condensation?
Yes, Home Energy Save GB provides free condensation surveys for homeowners concerned about moisture in their loft. One of our experienced assessors will inspect ventilation, insulation, and moisture sources to identify the cause of condensation. You will receive clear guidance on the most effective steps to reduce moisture and protect your loft, with no obligation to proceed with any work.
