Start Your Project with the Right Diagnosis

Better Decisions Start with Better Information.

The most expensive repair is one that you have to do twice.

From evaluating a persistent leak and planning a major restoration project to reviewing details before construction begins, N&S helps owners, consultants, architects, and contractors understand the issue before committing to a solution.

Our team brings more than 20 years of real-world waterproofing and restoration experience to help clients identify risks, evaluate options, and move forward with confidence.

Skills That Go Beyond Installation

Investigative Mindset

We don’t start with a product recommendation. We start by understanding how water is moving through the building and identifying the true source of the issue.

Design-Assist Expertise

We work alongside architects, consultants, and contractors to identify potential building envelope challenges before they become costly field issues.

Real World Perspective

Because we self-perform our work, our recommendations are informed by what actually works in the field—not just what looks good on paper.

Practical Recommendations

Our advice is grounded in the field, and we help clients weigh performance, constructability, budget, and maintenance considerations.

How We Help You Make the Right Call

Not every project starts with construction. Sometimes the most valuable thing you can do is assess a situation before deciding how to move forward.

Our experience helps our clients reduce risk, prioritize investments, and make informed decisions.
