Waterproofing the exterior is the best solution for wet basement problems as it stops the water coming in rather than managing it when it does come in as is the case for internal waterproofing.
Explained scope of work, price, options very well. Friendly and professional. Excellent job. Basement is dry!
They worked hard, they were polite and friendly. Invited me to see the work being done as the job progressed. Very interesting and not what most companies would do.
