"It has restored my faith in humanity"
I have been a lone parent since my younger daughter Bethanie was 4 days old. Over the last 5 years that Beth has been seriously ill I have quickly depleted my life savings… A friend told me about a grant towards the cost. When I got a call to say that I would get new doors and windows I could not believe it, I cried with relief.
Read the full testimonial
Part of my daughter's condition leaves her with a low immune system, making her vulnerable to bugs. It can breed in damp conditions, and I was forever cleaning condensation from my windows and trying to seal the frames to prevent further damp. I realised that I had to get new windows and doors for my daughter's sake.
No more constantly wiping condensation from the windows, listening to the wind blowing open the letter box, or being unable to get back in through the back door without brute force. You have not just replaced our windows and doors, to us it means so much more. My amazing and resilient daughter is now much safer medically, she feels safer knowing that no one can get in.
A huge thank you to everyone involved. I will never forget what you have done for us.
