Dormers & Extensions – House Renovations

Land-Tec specializes in excellent home remodels, and one of our most popular areas is expanding a home by installing dormer windows or creating extensions. Though dormer windows don’t increase the home’s footprint, they boost the square footage and lend unique character that always increases a home’s resale value. Home extensions provide endless opportunity for affordable costs. Rather than finding a new home, you can simply add on the workshop, bedroom, garage, or porch of your dreams. Our world-class remodeling contractors will build your extension from the ground up, and we will be there the whole time, making sure you get the very best result.
