I replaced old, low end windows in my porch with the most expensive, high R value windows that were available.
It was a big job - they started at 8 am and finished at 6 pm - with no breaks!
They were extremely meticulous - including spray foam on BOTH sides of each window - inside and outside.
The flashing was done perfecting - absolutely flawless - the seams were perfect and no scratches at all on any flashing.
they cleaned up everything upon completion.
i have used Home Depot Contracting many times over the years for big stuff eg new windows throughout house, new storm doors, new furnace, new water tank, new oak floors, new garage door etc
I am extremely pleased with the product AND the installation - AND the extended warranty in every instance.
