From start to finish, Richard and Bob displayed professionalism, skill, and a genuine passion for their craft. The attention to detail was incredible—from the high-quality materials used to the flawless execution of every feature. They transformed our basement into a beautiful, functional space that feels like an extension of the rest of our home, not just an afterthought.

Beyond the craftsmanship, they were punctual, respectful, and kept the work area tidy throughout the project. Richard communicated with us every step of the way, ensuring there were no surprises and that we were thrilled with the progress.

"We had Shire Group work on a remodel of a new office for us. They removed walls, framed in new doorways, and, in an ample space, created five new offices from the ground up. They asked questions that we never would have thought of. After completing the project, many visitors asked about their work besides the new offices. This shows how detailed they were; people could not tell new trim from old trim, removed doorways, moved light switches, and turned an old mailroom into extra space in our kitchen."

"Sunroom is an addition to the house, off the dining room, about 4 x 4 sqm Did a wonderful job, people were reliable, very friendly, kept us informed what they were doing and when. Alan, the owner , came frequently to check the work. We only hired our own electrician. Sunroom looks great. Took only a little longer than we thought, but was due to weather related back orders"

"We had four windows replaced with lead mitigation procedures.  They did an excellent job and nearly got the job done in one day and only had to come back a second day to finish up a bit of caulking.
