When people find out I'm vegan, the conversation usually stays on food. But once you start paying attention, animal products turn up in places you'd never expect, and a home renovation is one of the biggest. Paint, carpet, insulation, drywall, even the glue holding your floors down can contain animal-derived ingredients.
None of this means renovating has to be complicated. It just means asking a few more questions before the work starts. Here's where animal products tend to hide, and the cruelty-free swaps that work just as well.
Paint
Many conventional paints use casein, a milk protein, and some use shellac, which comes from an insect secretion. Others are tested on animals. The good news is that low-VOC and zero-VOC paint lines have grown fast, and a lot of them are vegan by default. Look for brands that state they're cruelty-free and don't use animal-derived binders. Bonus: these paints are usually better for your indoor air anyway.
Carpet and rugs
Wool is the obvious one, but it's not the only issue. Some carpet backings use animal-based adhesives, and certain rug pads do too. If you want the warmth of carpet without wool, look at recycled PET fiber, organic cotton, or plant fibers like jute and sisal. They wear well and they're often more affordable.
Insulation
Sheep's wool insulation exists and it's marketed as natural, but it isn't vegan. If you're insulating, recycled denim (cotton) insulation and cellulose insulation are both excellent, animal-free, and genuinely good at their job. Denim insulation in particular is easy to work with and quiet.
Adhesives, finishes, and the small stuff
This is where it gets granular. Some wood glues, floor finishes, and even certain drywall compounds use animal byproducts. You won't always get a clear answer from a contractor, and that's okay. The move is to ask your supplier for the product data or safety sheet and look for animal-derived ingredients. When in doubt, plant-based and synthetic options exist for nearly everything.
How to actually handle this with a contractor
- Bring it up early, before materials are ordered, not after.
- Frame it as a materials preference, the same way someone might ask for low-VOC or hypoallergenic. It's a normal request.
- Ask for product names and data sheets on the big-ticket items: paint, flooring, carpet, insulation.
- Pick your battles. The paint and carpet matter most and are easiest to swap. The trace adhesive in a subfloor is lower stakes.
You don't have to gut-check every screw. Focus on the materials that make up the bulk of what goes into your home, get those right, and you've handled the vast majority of it.
