What our clients say...

I wanted to show my appreciation for the work that your team carried out at my property last year. Although I was unsure whether I should contact you, your very knowledgeable team filled me with confidence so I decided to proceed. The cavity wall extraction that I had done has completely sorted out the damp I found inside my living room. Thanks to you and your team. I will surely be recommending SCIS to anyone who asks.


Thank you for all the team at SCIS for the extremely professional service that you have delivered in our properties for our tenants. I was particular impressed with the detail and knowledge throughout the process. The guidance during initial consultation and survey through to the quality of after care following installation was exceptional. Thanks again.
