This company quite possibly makes the WORST windows on the planet. I think those idiots advertising on TV24⁄7 for cheap windows probably have a considerably better product. We bought our house new in 2005 and had I known how bad these were we wouldn’t have bought it. Windows SAG and Leak air/water tremendously. Heck our front foyer window ROTTED and broke the seal between the glass(even though it had been caulked/painted multiple times!) in 2010 and started leaking water down into our basement. They wont stand behind their product in the least bit. Not sure if MLC actually installed the windows but EVERY one we’ve replaced so far leaked and our three bay windows were ALL held in with 1 – 2 nails per window, no insulation or sealing! We replaced with Mid to slightly high end Simonton windows and the difference is astounding. The house is quiet now and doesn’t leak water all over!
