Whether it’s a large scale waterproofing project to a small job that must get done, we apply the same quality, results driven attitude to get the job done.    We are especially focused on moisture-related problems which can create headaches for property owners and managers. They detract from a property’s overall appearance and undermine its structural integrity, posing potentially serious safety threats to tenants.

Our waterproofing and restoration services are designed to eliminate those worries for our customers. We combine experience with state-of-the-art techniques and materials to fix damaged building façades and restore them to their original beauty and structural integrity.

No job is too small, our Washington, D.C. building restoration services include repairs to leaky windows, deteriorated concrete, cracked masonry — the little jobs — that many large waterproofing and restoration companies would rather avoid.  As well, we are uniquely qualified to tackle the larger, complicated and multi-faceted projects which streamlines the contracting process for our customers.

To serve our customers even better, CBSI works with property managers and others to determine the scope of the work and if necessary, ways to budget and schedule the work over several years.
