Had landmark come in last year to provide a quote for a patio door, signed contract and never heard from them again, tried to chase them. Didn't get the door done. They called me back in the fall and I didn't want to do the work in the cold weather. They called me back in Spring, arranged re-measurement, ordered my door, called me back 7 weeks later to arrange installations. Installers were great, very friendly, professional job, I'm happy with the product as well. Lifetime warranty on product and labour is awesome.
