Fortis Black launches a Mountain States building-envelope platform with GXS, DD Reconstruction and Duro Exteriors, and names roofing as its next trade

Fortis Black, a Draper, Utah company led by CEO Ron Anderson, has launched as a platform bringing building-envelope contractors under common ownership. In an October 21 interview with TechBuzz News, the company said it completed its founding acquisitions of Guaranteed Waterproof and Construction (GXS), DD Reconstruction and Duro Exteriors in June 2026, creating a platform for commercial and residential exteriors in the Mountain States. Roofing is the next trade it plans to add.

The asset.

The three founding companies cover adjacent layers of the building envelope.

GXS and DD Reconstruction, which Chad Bolton built as an expansion of the GXS business, handle below-grade waterproofing, foundation protection, concrete restoration, traffic coatings and corrosion control for commercial properties.

Duro Exteriors, based in Lehi, Utah and led by founder and president Brennon Anderson, installs siding, brick veneer, stucco and architectural panel systems on commercial, multifamily and residential projects. It works with developers, builders and general contractors from pre-construction through installation.

The platform.

Ron Anderson’s background covers both the installation and manufacturing sides of the exterior: his family’s sheet-metal business, Manness Sheet Metal, and later building-products manufacturing, including leading brands such as Gerard Roofing. Chairman Davis Warnock was a general partner at Prelude, Mercato Partners’ early-stage fund, and co-founded 8228, the investment and holding vehicle that TechBuzz describes as the family office supporting Fortis Black.

Fortis Black says it will give founders shared finance, marketing and HR support while keeping the local leadership and reputation of each business. Its estimators use AI to check specification books against drawings before bidding. Anderson said a spec book review that used to take days now takes about an hour. Warnock called the business “a construction roll-up implementing technology to improve operations.” Anderson said windows are outside the current model.

Owning the handoff between trades.

Fortis Black is buying trades that sit next to each other on the same wall, so one company controls the transitions between them. Anderson’s point is that expensive failures happen at those transitions. On a typical multifamily project, he said, there are roughly 50,000 connection points where one material meets another. Waterproofing, flashing and cladding have to go in the right order and with compatible materials. When a schedule gets compressed or a detail falls between two scopes, the problem can show up in the first storm or years later as water damage.

The company’s answer is to have one project manager run both the waterproofing and the exterior work, and to review details with architects, owners and general contractors before crews start. For a commercial or multifamily general contractor, Warnock said, that means “one person to solve that problem or to hold accountable instead of, you know, ten, twenty, thirty different subcontractors.”

Bigger EBITDA, smaller multiple.

Warnock was direct about the financial logic. He told TechBuzz that combining smaller companies lets the group capture valuation arbitrage, with a larger consolidated EBITDA earning a higher exit multiple than each founder could reach alone. That is the logic behind most trades platforms, and it fits project-based exterior work well. Commercial and multifamily envelope work comes in larger contracts, so a construction-focused business can often add EBITDA faster than a service business built on thousands of small calls. Buyers value that work on a different multiple than recurring service revenue, and a larger EBITDA base can reach the same outcome at a lower multiple. We walked through that math in why private equity investors pay 18x for service and 8x for construction. The restoration and repair work inside GXS and DD Reconstruction, and the re-roofing a roofing add-on could bring, give the platform a second earnings profile alongside its new-construction work.

The M&A environment.

Building-envelope and exterior contractors are drawing dedicated capital. This month, Bertram Capital invested in Percopo Coatings to start a Southeast commercial coatings and restoration platform, and Banner Capital launched Roof Restoration Group in the Southwest. Fortis Black is a founder-led version of the same idea, backed by a holding company and family office rather than a traditional private equity fund.

What it means.

For waterproofing, siding, masonry, stucco, panel and roofing contractors in Utah and the Mountain States, commercial and residential alike, Fortis Black is a new local buyer that has said what it wants next. Owners talking to a platform like this should ask how the combined earnings will be valued, whether part of the consideration is equity in the holding company, and how a shared project management model would change scheduling for their crews. It also helps to know your own split between repair, restoration and re-roofing work and new-construction bids, since each attracts its own set of buyers.
