Hello Howard. I have also been an investor for 20 years.
I used Tony/iDeal several years ago to replace carpet with vinyl plank in three bedrooms and a staircase (for an east FW property). I was not happy with the quality of craftmanship and had a couple of items I had to call them back for or had to live with. I won't go into the list here... If you like, contact me offline, and I can send photos.
In the interim of tenant wear, I found that the worst/most obvious goof was that transition strips were installed incorrectly, so that repeated but normal pressure on them from people going up and down the stairs caused almost every one of them to split in half lengthwise and become a safety hazard. Not to mention the fact that they had put small nails in the strips, which is where the splits started.
I replaced a couple of them that were completely broken in two. One transition strip from HD/Lowes, long enough to get two replacements from was $35+ then. And of course was not a 1:1 color match. But I installed them correctly (glue the top/horizontal piece flush first before you press the vertical piece to the riser) so those two are good! The rest are a blemish to discerning applicants...
Caveat: My standards are probably higher than most landlords'. What's an eyesore and shoddy work to me might not faze anyone else, much less a prospective tenant. However, one "discerning applicant" did notice all the split transition strips and for whatever reason, did not follow through.
2c, Paula
