What Harth Builders does

Harth Builders is a residential design-build remodeling and custom home firm founded in 1996 by Allyn Harth and headquartered in Lower Gwynedd (Spring House), Pennsylvania. The company is led since 2008 by second-generation President and Chief Visionary Officer Gregory Harth and serves homeowners across five Pennsylvania counties (Bucks, Chester, Delaware, Montgomery, and Philadelphia) plus, as of January 2026, the New Jersey Shore. Service lines span kitchen and bathroom remodeling, whole-house renovations, home additions, exterior and outdoor living projects, historic home restoration, aging-in-place modifications, interior styling, nonprofit capital improvements, and ground-up custom homes, including the Port Royal Reserve enclave development in Roxborough.

The operating model is built on a proprietary 10-step Design-Build Process that integrates architectural design, product selection, and construction under a single contract, with a 6-14 week design development phase including meetings every 10 days and a mandatory production-staff/trade walkthrough at two-thirds design completion to verify constructibility. Supporting technology includes CoConstruct for client project management and communication and GuildQuality for satisfaction tracking; the credentialed in-house team holds CAPS, MCR, LEED AP, AIA, CLC, EPA RRP, and Master Plumber designations and completes more than 200 hours of annual professional education. A modular-home offering is delivered through a partnership with Westchester Modular Homes.

Revenue is generated on a project basis with one-time fees per engagement, priced from approximately $12K for a powder-room remodel to $485+/SF for custom homes and $525+/SF for additions. The go-to-market is sales-led and direct-to-consumer, beginning with a 45-90 minute in-home consultation, followed by an Opinion of Probable Cost (OPC), a design retainer of 6-10% of OPC, a 10% construction deposit, and weekly stage payments through construction. Two-year warranty coverage with proactive 6/12/18/24-month follow-ups supports a referral engine that delivers over 75% of revenue from past clients and referrals, with some households on their fourth or fifth engagement.
