My mum just had her carpet fitted yesterday . Bought the thickest best underlay .and good carpet . But since fitting it’s snells bad even today like a cat litter box also found out they have glued All the underlay to the floor. she had the grippers down
Any help before I go down there Monday and demand a refund and removal.
Ensuring you keep the underlay straight and gap-free, staple it along its edges inside the gripper. Use adhesive if you are laying carpet onto a concrete floor. Use tape to stick along the full length of joins. Use the knife to trim off any excess underlay inside the grippers.
Post your job & get responses from local tradespeople. Read reviews before you decide to hire.
Might be worth telling them now just so there's a problem "on the record" but that smell's normal and can easily take 4-5 days to go, in extreme cases even a couple of weeks. Great info here: https://blog.fantasticservices.com/how-to-remove-or-reduce-new-carpet-smell-tips/
