“Working with Brace was absolutely a great experience for me.”

“Not only were they very professional, attentive to details and cordial when responding to my concerns, but they were key to getting the renovation done right and ultimately increasing the equity value of my property significantly.

And best of all, I ended up turning a “lemon” into the home of my dreams!”
