Had a glassier install windows to reduce traffic noise from a main rd that hardly did anything at all and charged me $7000.
I had Greg come past who not only replaced the previous glass with thicker double glazed glass but also with a much improved seal for under $4000. Although I can still hear the traffic if I listen for it (it is a heritage house after all that has those old style air vents) the traffic is dampened soooo much and I’m very happy I gave it another crack with Greg.

Approximate cost: $3900
