Flooring installers that install Lowe's and Home Depot's flooring do not work for these companies directly. Rather, they all work for different floor installing companies. In this area of the country, Romanoff Flooring Installers handles almost all of the installations for one of those two big box stores. I forget which one exactlly, but Romanoff's has approached me. In Erie, "Gary ?" who has his own carpet store, supplies installers for Home Depot! Talk about a conflict of interest! Home Depot and Lowe's send out measuring people that look the job over and give the customers a price and then the job is in the hands of Romanoff or I guess "Gary" in Erie. If HD or Lowe's let me measure the job, look it over and paid me directly I'd be working for them now! The tradesman who installed your door probably was NOT on HD or Lowe's payroll. He was either a sub contractor to the store or worked for a sub contractor to the store.
In all fairness to Romanoff, the measuring people at HD and Lowe's have no idea what they are doing. At my local HD, I pick up material for customers that don't want HD measuring OR installing. I am constantly amazed at the people in the flooring department who think there are 3 square feet in a square yard. They send out trim metals for jobs and don't allow for the centering of nail holes in any given doorway. Four 3 foot doorways will probably require at least 13 lineal feet etc. I deal with HD and Lowe's people who tell customers to install the pad with the moisture barrier DOWN ! Almost ALL pad has a "skin" ... a plastic membrane on one side. That is there so the carpet will slide across the pad. If it's installed upside down, the friction from the backing of the carpet will rub on the underside of the pad (which is installed upside down!) and roll it off the floor. Some pads do have a moisture barrier but most don't. I see HD and Lowe's people positioning seams where they shouldn't be etc. etc.
The Romanoff installers, for instance, are always under pressure to correct HD and Lowe's mistakes and Romanoff doesn't want to rock the boat and back charge HD and Lowe's to pay trip charges. I make the same money as all these installers, some of whom I know quite well.
Home Depot and Lowe's are 2 of my favorite stores and I send customers there all the time."In a sense" you might say I do work for them but the customer buys the material from them and the customer pays me directly.
I tell people all the time to have HD give them a firm price on the material AND labor and don't tell me. Then I will measure the job and give them a price as if I walked into the store, bought that same flooring and charged my usual labor prices. I am always lower. Lowe's and Home Depot CHARGE YOU to measure ($35 - $40 ?) and promise to refund that money if you have them install it.
I have a few landlord accounts which is my preference. They are always empty units and I don't have to mess with furniture. I measure everything and the landlord picks out the style and color, he pays over the phone with a credit card and I will pick it up and deliver it to a jobsite for free. The Covid madness interfered with landlords evicting deadbeat renters and that affected me. My left hip gives me trouble and the VA tells me it's rheumatoid arthritis. I have a great back and great knees. So, I am slow but my job has always been payed as piecework anyways. I am ONE decent account away from being comfortable.
I hope you read fast? Sorry about the novel!
