I work in home improvements so I have worked for gay couples many times. Some of them can be tough to please. We had to try to remove stain from some freshly stained floors in the color the gay couple chose and then later said was too dark. Thankfully they were satisfied when we buffed around with laquer thinner and took off enough to turn a rag brown. Didn't change the color one bit but they thought it did. LOL
That was one experience with a gay couple to add to the 30 nasty hetero couples who were even harder to please.
As far as I'm aware, there is no recognized religious objection to performing home improvement services for difficult customers, regardless of sexual identity.
