Used Landmark 10 years ago on our previous house without issue, this time the complete opposite. Two people were by to confirm window measurements. During manufacturing it was discovered double hung wouldn't fit so it was decided to downgrade the windows to sliders without our consent. Exterior light smashed during removal, window security locks not installed and fingerprints on the insides of the panes. Even though we stressed Covid precautions there was seemingly no steps or procedures in place. Lastly, my credit card was not accepted because apparently I was given a discount for paying by cheque which was never discussed or on the contract anywhere.
