Justin Gokgol, Senior Surveyor, Winchester City Council

Nolan Commercial provided the most cost effective price and was therefore awarded the works. The replacement windows and doors will provide the residents with improved thermal and acoustic installation as well as the added security and controlled ventilation. Nolan Commercial provided an excellent service. The work was carried out on time and within budget. All our residents were kept informed and were dealt with sympathetically.
