Can't recommend David highly enough. I have been quoted more than 3k to seal our home. We moved in 2 yrs ago. He came over. And told me... your house was sealed prior by last owner. I will patch some spots and identified an unsealed area. Couple hundred bucks. He could have told me the whole house needed sealed and Done same work. But charged a few grand. Honest. Nice. Responsible. Quick. Seriously refreshing to deal with a guy like this.
