I contacted Len to get my windows measured up ETC to be replaced and upgraded. He sent out John and Jason to remove the nearly 50 years old Stegbar Aluminium ones. Then put in the new, better, thicker tinted glass with frames in Monument colour. Night n day difference. Amazing job, John especially. They even fixed my 50 year old sliding front door also. Replaced the runners. Good blokes and worth the wait and money.
