I contracted Boom GC for some demo work that was needed prior to countertops installation. Santiago quoted the work remotely by looking at pictures I sent him. On the day of, he texted me promptly as they were running late (Seattle traffic). The work was completed efficiently and they took care of the surroundings and cleaned up very well after. Extremely satisfied and I will be looking for them to so additional GC work when we need it.

Santiago and his crew were great at tackling my outdoor yard fence repair and mulching project. Have a fair estimate and tackles the task to the best of my expectations. Cleaned up and left everything in good shape. Did the job as expected and were quick and efficient with the work. Highly recommend them again for the future.
