We received the doors and windows at 3pm today and I just wanted to say how pleased we were with what we received. Your delivery fullah - Terry was awesome - and we literally unloaded them off the trailer and put them straight into place - PERFECT fit.....so brilliant on your part with specs and production and our builder. So thank you all soo much. Your communication has been great, your timeliness (production thru delivery) excellent and pricing is great. Once again, "Nga mihi ki a koutou"
