Customer Reviews
EXCELLENT Based on 1845 reviews Posted on Google Rebecca WilliamsTrustindex verifies that the original source of the review is Google. We are providing this review on the day of installation. We had DPC Plus installed. Installers arrived on time, were professional and completed the work to a good standard.Posted on Google Michal KvočekTrustindex verifies that the original source of the review is Google. I had a survey carried out to check for a possible damp or mould issue in my flat. The surveyor (Johnny) was very professional, thorough, and honest. After a careful inspection, he confirmed that there wasn't a problem they could help with. I really appreciated his approach because the survey was free, and he could have easily tried to find an issue that wasn't there. Instead, he was honest and gave me some genuinely useful advice on how to prevent future problems. I would definitely recommend their service.Posted on Google Andrew HattonTrustindex verifies that the original source of the review is Google. From survey to completion the service was excellent.

What is Damp Proofing?
Damp proofing prevents moisture from entering your home through the walls, floors or roof. It typically uses materials like membranes or sealants to stop issues such as rising damp, condensation or water intrusion.
For homeowners, effective damp proofing protects the building’s structure, helps prevent damage to plaster and timber, and reduces the risk of mould.

Rising Damp Solutions In North Wales
Rising damp is typically treated by injecting a high performance silicone based damp proof course into the affected walls. Where necessary, any salt contaminated or deteriorated plaster is carefully removed and replaced with specialist renovating plaster or a cavity wall membrane system designed to manage moisture effectively.
While many properties across North Wales were originally constructed with a damp proof course, problems can still arise over time due to age, wear and exposure to coastal weather conditions and driving rain.
All of our rising damp treatments are supported by a 25 year guarantee, providing long term protection and peace of mind for your property.

Penetrating Damp Solutions in North Wales
If you have noticed mould growth, damp patches or watermarks on your walls or ceilings, it could be a sign of penetrating damp within your property.
One of our qualified surveyors will carry out a detailed inspection of your North Wales home to identify the source of the issue and recommend the most suitable course of action.
To help minimise the risk of further moisture entering the property, we can also apply a high quality water repellent treatment to the external masonry, providing added protection against harsh coastal conditions and the elements.


What to Expect From Our FREE Damp Survey

What are the common signs of damp in North Wales homes?
In North Wales, damp often shows itself through visible signs such as peeling paint, bubbling plaster, musty odours and mould growth on walls or ceilings. You may also notice tide marks on lower walls which can indicate rising damp. Due to the coastal climate and higher levels of rainfall, properties in this region can be more exposed to moisture related issues. At Home Energy Save GB, we carry out detailed surveys to identify the exact cause, ensuring the correct treatment is applied rather than a one size fits all solution.
What causes damp problems in properties across North Wales?
Damp can be caused by a range of factors including rising moisture from the ground, water penetrating through external walls or condensation from poor ventilation. In North Wales, exposure to driving rain, coastal winds and older building structures can all contribute. Defective guttering, damaged pointing or blocked cavities are also common causes. Our team focuses on identifying the root issue during the survey stage so we can recommend the most effective and long lasting solution for your property.
What does a damp proofing survey involve?
Our damp proofing surveys across North Wales involve a thorough inspection of both internal and external areas of your property. We use professional diagnostic tools to measure moisture levels and identify how water is entering the building. The survey allows us to distinguish between rising damp, penetrating damp and condensation. Following the inspection, you will receive a clear report outlining our findings and recommended treatments, giving you full confidence before making any decisions.
Will damp proofing work permanently?
When carried out correctly, damp proofing can provide long term protection for your property. At Home Energy Save GB, our treatments are designed to address the root cause of the issue rather than just the symptoms. We also provide guarantees of up to 25 years, giving you peace of mind. Ongoing maintenance such as keeping gutters clear and ensuring good ventilation will also help maintain the effectiveness of the treatment over time.
How much does damp proofing cost?
The cost of damp proofing varies depending on the severity of the issue, the size of the affected area and the treatment required. We do not believe in fixed pricing without a proper inspection, as every property is different. That is why we offer free surveys across North Wales, allowing us to provide an accurate and transparent quote. Our aim is to deliver value through long lasting solutions that protect your home and prevent costly problems in the future.
