Wall Insulation

The purpose of insulation is to minimise heat escaping through the walls, floors, and roofs. Insulation enables your home to retain warmth for longer, which maximises your energy efficiency and reduces your carbon footprint saving you money on your energy bills. Most importantly it makes your home a better and more comfortable place to live.

Solid Wall Insulation is one of the best ways to improve thermal efficiency. However each property is individual and will require assessment on it's own merits.


A single measure can be installed or a combination can be used to achieve increased thermal performance of a property.

Cause of Damp

Damp is one of the most annoying problems around the home and sometimes one of the most difficult to understand and eradicate. Without proper diagnosis and the right damp proofing treatment damp can, in the long term, cause irreparable structural damage to affected areas. If left untreated it can become costly to cure and become a serious risk to health.

We can carry out a damp assessment to get to the root cause of the issue and identify the correct damp treatment or repairs to cure the problem whatever that may take. We will never try to cover the problem up or suggest a treatment if we haven't identified and resolved the cause.

You can learn more about our damp treatment service here.

Did you know insulating your home in different ways can help prevent future damp problems by increasing the temperature of internal walls and weatherproofing the exterior.



Green Energy

Combining any number of our services we can offer an extended and bespoke home improvements package which can include further in-depth renovations such as:

Room Conversions

Converting an unused area of your home can increase space without adding an extension. Lofts, garages and basements can be reworked into open living areas, using the space you already have. We use our high performance insulation systems in our conversions ensuring the new space is cosy and comfortable. Our team will create a conversion to best suit your requirements.

Home Retrofits

Our full retrofits can range from bespoke extensions through to whole house renovations and internal remodeling. Using modern building techniques, sustainable materials and contemporary thinking, we aim to create low impact, high performing buildings. This can be achieved through modifying, renovating, designing and building; either in stages or as a complete project.

Alternative Heating Systems and Renewable Energy Sources

Consider heating your home differently, we can install underfloor and infrared heating systems leaving you less reliant on carbon heavy heating systems.

Solar panels can heat your hot water or generate green electricity for your home. 

Reduce Heating Bills

Whatever your dreams are for a better home, big or small, contact us and let us help you realise those dreams, building you a better home to build us all a better world.

Katy White

We are so pleased with the results and the whole process of dealing with Cobalt. Every one of the workmen who worked on our house were professional, polite and hardworking. Chris has been instrumental in making sure everything was done to a high standard and in a timely manner. Would definitely recommend Cobalt Carbon Free.

Louise Dale

“Chris and the team were highly professional and have done the most amazing job for us. Due to the age of our property along with previous work that had been done, a few issues were found along the way, but Cobalt were extremely efficient in rectifying these. Within a week we had joists replaced throughout, new insulated flooring, a full damp proof course and more! The team went above and beyond our expectations, I am so happy with how everything has turned out. I would highly recommend the Cobalt team”.

Tim David

“The Cobalt staff were highly professional and worked with us to provide a high quality of work on our project. They were always available to talk to us. The project was on an older house and this threw up some unpredicted issues, but Cobalt were quick to come up with cost effective solutions for us. Overall, we were extremely satisfied with the way the project went and would highly recommend the Cobalt team”.
