Stratum Enclosure Launches in DC Metro, Bringing Specialized Enclosure Commissioning to Projects of Every Size

Stratum Enclosure Launches in DC Metro to Bring Specialized Building Enclosure Commissioning to Mid-Atlantic Developers and Architects
New Arlington-based consulting firm offers BECxp and CxA+BE certified expertise grounded in ASTM E2813 and NIBS Guideline 3, serving developers, architects, and owners on projects of every size.
ARLINGTON, VA, May 4, 2026 - Stratum Enclosure, a specialized building enclosure consulting firm, has officially launched in the Washington DC metro area to serve developers, architects, general contractors, and owners across the Mid-Atlantic and East Coast. Founded by Certified Building Enclosure Commissioning Professional Robert (BECxp, CxA+BE), the firm is built around a focused premise: many of the costly enclosure failures that surface in completed buildings, including water intrusion, air leakage, condensation, and premature material degradation, are preventable with rigorous commissioning and design phase review applied early in the project.
Projects of every size, from small renovations and tenant fit-outs to mid-rise multifamily, mixed-use developments, boutique hospitality, and adaptive reuse conversions, have historically struggled to access this level of specialized expertise. Larger national engineering firms typically prioritize institutional and federal work, leaving private developers, architects, and owners without a clear path to qualified enclosure consulting regardless of project budget. Stratum Enclosure was founded specifically to close that gap, and the firm engages on projects of all sizes where the building enclosure matters, which is to say every project.
"The enclosure is the most expensive system in a building to fix after construction is complete," said the firm's founder. "An exterior wall failure that costs a few thousand dollars to address in design can cost a hundred times that to remediate after occupancy, and that is before considering business interruption, tenant displacement, and reputational damage. That math holds whether the project is a small renovation or a full ground up development. Our value to a developer or architect is straightforward. We catch the problem when it is still on paper or still on the scaffold, not when it is behind finished drywall."
Stratum Enclosure offers four core service lines: design phase design reviews, peer review, construction phase services, and full building enclosure commissioning. Each engagement is grounded in the recognized industry standards that govern enclosure performance, including ASTM E2813 Standard Practice for Building Enclosure Commissioning, NIBS Guideline 3 for Building Enclosure Commissioning Process, and ASTM E1105 Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform or Cyclic Static Air Pressure Difference. This standards based approach gives clients defensible documentation, repeatable test protocols, and a clear paper trail that holds up in performance disputes and warranty claims.
The firm's positioning addresses a specific frustration in the current market. Many architects and developers report that enclosure issues only get serious attention after a problem has already occurred, often during punch list or in the first warranty year. By that point, the trades have demobilized, the systems are concealed, and the cost of investigation alone can exceed what proper commissioning would have cost during construction. Stratum Enclosure inverts that sequence by embedding qualified enclosure oversight at the design table and on the construction site from the outset.
Service offerings include curtain wall and storefront performance testing, air barrier continuity verification, waterproofing system review, fenestration assembly evaluation, mockup observation, and the full ASTM E2813 and NIBS Guideline 3 commissioning process from owner project requirements through systems manual delivery. Field testing capabilities cover ASTM E1105 chamber water testing, AAMA 501.1 and 501.2 protocols, ASTM E783 air infiltration testing, and ASTM E1186 air barrier leakage location.
Geographic focus spans the Mid-Atlantic and East Coast, with active capacity in Virginia, Maryland, the District of Columbia, Delaware, Pennsylvania, New Jersey, New York, and the Carolinas. The firm is structured to engage on private development projects, boutique hospitality and adaptive reuse work, multifamily and mixed-use, commercial office and tenant fit-out programs, and smaller renovation and addition projects where specialized enclosure consulting has typically been out of reach.
For developers and architects evaluating an enclosure consultant, Stratum Enclosure emphasizes three differentiators. First, every project is led directly by a credentialed BECxp and CxA+BE professional, not delegated to junior staff. Second, deliverables are written to the language of recognized industry standards, which gives the entire project team, including the design architect, contractor, and owner, a common reference framework. Third, the firm operates at a scale that allows responsiveness and direct principal involvement, which mid-market projects rarely receive from larger national consulting houses.
Inquiries from developers, architects, general contractors, and owners are welcomed. Stratum Enclosure is currently accepting engagements for projects bidding or breaking ground in 2026 and 2027.

Stratum Enclosure: A Portrait
Stratum Enclosure is an independent building enclosure consulting firm based in Arlington, Virginia, founded on a single observation: the most expensive failures in modern construction almost always happen at the building enclosure, and almost all of them are preventable.
The exterior wall, the roof, the windows, the waterproofing, the air barrier, the joints between them, this is the system that separates a comfortable, dry, energy efficient building from a callback nightmare. When it fails, the costs compound. Water finds its way into finishes, insulation, and structure. Air leakage drives mechanical loads up and indoor air quality down. Sealant joints open. Curtain walls weep. Owners get angry, lawyers get involved, and the trades that built it are long gone. Stratum Enclosure exists to make sure none of that happens to its clients.
The firm operates at the intersection of design and construction, embedded early enough to influence drawings and specifications, and present enough on site to catch installation issues while they can still be corrected. Services span four disciplines: design phase design reviews, peer review, construction phase services, and full building enclosure commissioning. Every engagement is grounded in the recognized industry standards that govern enclosure performance, including ASTM E2813, NIBS Guideline 3, ASTM E1105, ASTM E783, ASTM E1186, and the AAMA 501 series. This is not a stylistic choice. It is what gives clients defensible documentation when warranties are tested and what gives the project team a common reference frame when disputes arise.
The firm is led by a Certified Building Enclosure Commissioning Professional holding both BECxp and CxA+BE credentials, with a background spanning federal and mission critical facilities, hospitality, multifamily, and commercial work. Every project is led directly by the principal, not delegated to junior staff. Deliverables are written in the language of the standards, and recommendations are framed in the voice of a commissioning agent, advisory rather than directive, technical rather than theatrical.
Stratum Enclosure serves developers, architects, general contractors, and owners across the Mid-Atlantic and East Coast, with active capacity from Virginia through New York and into the Carolinas. The client roster spans private development, boutique hospitality, adaptive reuse, multifamily, mixed-use, commercial fit-out, and small renovation work. The firm engages on projects of every size, because the enclosure matters whether the construction value is six figures or eight.
The brand is built on three commitments. Standards based rigor, so every observation and test result holds up. Direct principal involvement, so clients always know who is reading their drawings and walking their site. And honest counsel, delivered early, when fixing the problem still costs less than living with it.
Stratum Enclosure. Independent expertise. Standards based delivery. Buildings that perform.
