Installation of new windows and doors.

Had 8 new windows and 3 new doors installed professionally and efficiently within 3.5 days. Very happy with the quality and price was reasonable. Thanks to Russell & Shaun and also to Dale and his team. Thoroughly recommend that you get a quote from Sapphire if you want new doors and/or windows. Excellent service from this well established family business.
