I found Better choice caulking on Kijiji initially. Alex did a great job removing all my old caulking on my house and replacing with high quality caulking and filling in gaps with styrofoam. He found some areas that didn’t have any caulking at all and fixed them. I also asked him to come back later to do some areas related to my basement project and he followed through and did that even though I had paid him. he also has competitive prices. I highly recommend him for caulking work.
