What Our Clients Say...

We are absolutely thrilled to have had the Cornerstone Insulation. Our property is already benefiting from the insulation.

We are certainly feeling warmer and have already saved on propane gas.

We cannot thank your Site Manager, Matt Ellwood, enough for all is attention. He is very thorough and always polite. The team that insulated our home were very hard working and also very thorough - extremely nice people.

We are more than happy with all the work that has been carried out.

Many, many thanks indeed for the M+S Gift Voucher. It was a surprise to receive. It is us that thanks you most sincerely.

We have recently had exterior insulation applied to the upper storey of our house in Norwich. The team who carried out the work consisted of Nick and Tim, the plasterers, Tom their labourer, Jimmy who undertook final finishing details, making good and general clearing up and Adam who was the team leader.

My wife and I are experienced 'renovators' and I have to say that we were extremely pleased with the way that the project was undertaken and managed from start to finish. The promised timescales were met (despite the exigencies of the weather) we were kept fully informed by Adam at all times, the work was completed to a high standard and the worksite was kept clean and tidy throughout the process and on final completion.

The team members were always polite and friendly and very professional. They all went out of their way to ensure that we were happy with what they were doing and went the extra mile to ensure that the job was done well and to the highest standards. They were a credit to your company, particularly Adam who was an excellent co-ordinator and very good at keeping us informed. Nothing was too much trouble for him and his cheery manner was a delight. It was clear to see that he took his role very seriously and that to him, customer satisfaction was paramount.

We felt that you might like to receive some specific feedback, particularly positive remarks such as these, when customers are always ready to complain and good service and a job well done too often go unheeded. With all best wishes.

I felt compelled to write to say how delighted I was with Floyd and his work. His attitude was so sunny and positive, and he was exceptionally thorough checking pipes for leaks before lagging them, and being clear about which areas we needed access to and so on. I am completely delighted with the result and would recommend Floyd and his work to anyone without reservation. Congratulations on recruiting such a great employee and ambassador for your company. With warm regards.

Cornerstone were very professional from the initial site visit through to completion. With considerate trades and an eye on the overall finish, they have managed to enhance our home whilst providing warmth for the winter.

I’m not sure people realise just how cold and expensive it is to heat a ‘concrete-no fines’ construction, not to mention the drafts and the odd damp patch. If it wasn’t for the local authorities funding, all this wouldn’t have been possible – but, it wouldn’t have been possible without you guys either and I will not hesitate to recommend Cornerstone in the future.

Can I take this opportunity to pas on my gratitude for the way you have insulated my house on the outside. We have been pleased with the finish, also how the job was conducted throughout.

Without this funding we wouldn't have been available to afford the works and I can say it's the best £3,000 I have spent. It makes a refreshing change to see a job carried out to a high standard and conducted in a professional manor.

Wow, what a great job. I can't thank everyone at Cornerstone enough, my house now looks amazing and even better, it's saving me on my heating bill! It was a good day when the council decided to use Cornerstone to insulate their houses, and I got a knock on my door asking if I wanted mine done as well. Every single person who worked on my house was polite, clean and tidy and most importantly did a fantastic job. Even the office guys were so helpful. Once again, thank you!

I would like to take the time to thank you for the a fantastic job on my property. I was unaware of any funding that could be available until Cornerstone approached me about the works being undertaken on my property, of course I swiftly took the offer up.

Without the funding I must say it would have been difficult for us to find the full cost price. All of the Cornerstone staff and operatives were polite and helpful throughout the whole project. And as for my heating bills, I can safely say I have noticed a huge difference not only with the warmth of my house but also my bills at the end of the month!

I am just writing to say how pleased I am with the external wall insulation you did on my bungalow. It looks a completely new building and everyone thinks it looks good!

This is all due to the team of young men whose work was exceptional, they certainly worked well as a team and never slacked at all.

The extra praise has to go to Wes (site manager), he was so particular in whatever he did and my thanks go to him for leaving me with a lovely bungalow, which is so much warmer and a cosier place for me. I am also using less heating!

Your firm is very reputable and I hope your good work will continue.

I would just like to say how delighted I am with your work on my cottage, and a huge thank you. The transformation is remarkable; my family and friends have made very favourable comments. I would have no hesitation in commissioning Cornerstones again for more work and I have no hesitation in recommending your services to others looking to have this type of work done. In my view, a truly professional building company producing outstanding results – well done, A+ across the board.

I would just like to thank you for the wonderful job you did with the external wall insulation on our bungalow. Before the works were completed we struggled to keep warm, with the thermostat never turning off. The gas bills were extremely high and we often struggled to pay them. After your external survey and having an EPC carried out, you managed to find ECO funding which greatly reduced the overall cost of the work and made it affordable. Without the funding we wouldn't have been able to pay.

Since having the works completed, the thermostat now turns off, i.e. the boiler isn't constantly running, and we have noticed that the temperature in the bungalow is a lot more even. When I get up in the morning the place still feels warm from the previous evening. Our gas bills have now reduced dramatically, making them more affordable. We are very please with the service we received and would recommend your company to all of our friends.

I can confirm that I have recently had 4 of my properties in Milton Keynes covered in exterior wall insulation by Cornerstone. The results were amazing!

This coating was very neatly and professionally carried out and it totally transformed my properties. The properties had steel cladding on the exterior, which quite honestly looked horrible, and the walls were poorly insulated, but once Cornerstone had completed their work the outside was delightful. In fact, my properties now make the rest of the neighbouring houses look bad!

My tenants who were in occupation whilst the work was being carried out said the workmen were very considerate and they always tidied up after themselves at the end of the day. The inconvenience of having a major overhaul at the front and back of my properties was minimised by Cornerstones team of workers. Scaffolding was erected and a skip was hired to take all the debris and the end result was a fantastic job, which I was really happy with.

My tenants immediately felt the benefits of the insulation as the house was draughty before and now it is positively much warmer.

This work has also increased the value of my properties and made them more saleable. Cornerstone is an excellent company with a great, considerate and conscientious workforce. The product is terrific and I am happy to supply the addresses of my properties for anyone to inspect and see for themselves. I would definitely recommend Cornerstone.
