Precision Waterproofing Contractors

Built to
perform.
Long after
handover.

We consult and install high-end waterproofing systems for builders who know that getting it right the first time is always cheaper than fixing it later.

Air & Water Barriers

Properly installed building enclosure systems that manage bulk water, vapor, and air movement — protecting the structure from the outside in.

Rough Opening & Window Waterproofing

The most overlooked detail in any build. We treat every opening as a potential failure point — because that's exactly what it is if not done right.

Balcony Coatings

Including over occupied space. High-performance coating systems installed with the prep and precision required to protect both the structure and the people below.

About Us

At Building Science Group LLC, we specialize in air and water barriers, rough opening waterproofing, and high-end balcony coating systems.

Unfortunately, we have an obsession with getting it right — and it shows in every detail of our work.

We're equipped with the best materials and methods in the industry, ensuring every project benefits from waterproofing that actually performs. At Building Science Group, your build becomes our mission — and we won't hand it off until it's done right.

Prep First, Always

Prep is the most important — and most overlooked — part of waterproofing.

Consulting & Installation

We can advise on system selection and sequencing during design, then execute the install with the same team and same standards.

Built for Discerning Builders

We're not the right fit for every job, and that's by design. We work with builders who care about long-term performance, not just getting past inspection.

Our Commitment

We're equipped with the best materials and methods in the industry, ensuring every project benefits from waterproofing that actually performs. At Building Science Group LLC, your build becomes our mission — and we won't hand it off until it's done right.
