What Quality Builders does

Quality Builders (legal entity: QB Construction Inc) is a Chicago-based general contracting company founded in 2020 by Jonathan Klemm. The firm delivers interior and exterior renovations, home additions, basement rehabs and digdowns, kitchen and bath remodels, apartment unit turnovers, condo renovations, and new construction for real estate investors, homeowners, and property managers across the Chicago metropolitan area and surrounding suburbs. Project values span roughly $20,000 for cosmetic per-unit work up to $700,000-$790,000 for new construction, with the company serving single-family homes, condos, 2-4 unit multifamily, and 5+ unit multifamily property types.

Quality Builders has built a proprietary technology stack it brands 'GC-Tech,' comprising the QB Instant Estimate tool (an online calculator providing rough cost ranges by property type, renovation type, and square footage), a project management software platform offering real-time schedule and budget tracking, a Past Project Data Repository storing cost details across completed projects for ROI decision-making, and a QB Sub Portal for subcontractor invoice and payment management. The company reports deploying BIM modeling, lidar scans, 3D printing, and virtual reality for finish material selection. Quality Builders holds Illinois General Contractor License #TGC116360, is an FHA 203k Certified Contractor, a member of the National Association of the Remodeling Industry (NARI), and a member of Chicago tech hub 1871.

The firm earns revenue from percentage-based GC fees of 10-30% of project cost and from construction and renovation service revenue, with project costs ranging from $20,000 to $790,000. Distribution combines a self-serve Instant Estimate tool with inside sales (free consultations, site walkthroughs, detailed proposals, 1:1 video calls) and event-driven investor outreach including Chicago investor meetups, podcast appearances, and a $500-per-referral referral program. Marketing spans content (blog, e-books, rehab/rental/value calculators), organic social (Instagram, TikTok, YouTube, Facebook, LinkedIn), SEO location pages for Chicago neighborhoods and suburbs, and earned media placements in Newsweek, BiggerPockets, Consumer Affairs, and U.S. News & World Report. Quality Builders operates as a privately held, founder-led single-entity firm with no disclosed institutional funding or parent company.

Broad incumbents

• Opendoor: Large iBuyer that purchases, renovates, and resells homes at scale, operating an internal GC-like function. Represents a more institutionalized, capital-intensive version of QB's investor-focused renovation model.
• Offerpad: iBuyer offering direct home purchase with renovation built into the workflow, including an instant offer and rehab solution. Comparable in marrying technology with residential renovation for investor-style customers.
• Window Nation / Improveit! Home Improvements: Multi-state home remodeling operator with strong digital marketing and sales infrastructure focused on residential renovations. Comparable marketing-driven, vertically organized home improvement GC model.

Direct peers

• Rebuilt: Tech-enabled residential renovation firm historically focused on serving real estate investors with project management, cost estimation, and turnkey rehab services. The closest direct analog to QB's GC-Tech, investor-first positioning.
• Power Home Remodeling: Large U.S. residential remodeling general contractor with a strong marketing engine, multi-market footprint, and investor/owner customer mix. Comparable to QB in core GC services (full interior/exterior renovations, kitchen and bath remodels) but at much greater scale and geographic breadth.
• Revive: Real estate renovation platform offering instant cost estimates, contractor matching, and project management to homeowners and investors. Overlaps with QB on instant estimation and investor-focused renovation workflow.

Emerging players

• HomeVestors: National franchise network that buys, renovates, and resells homes, with deep relationships to the investor customer base QB targets. Comparable audience overlap and renovation intensity, though HomeVestors operates a franchise model rather than a centralized GC platform.

Others

• BiggerPockets: Largest U.S. real estate investing community and education platform, where QB has featured content. Strongly comparable on investor audience and intent, with QB already using BP as a marketing channel.
• Angi: Home services marketplace connecting homeowners with local contractors, including remodeling and renovation professionals. Relevant as both a lead source and competitive channel for QB's homeowner segment.
• Houzz Pro: Software and lead-generation platform for home remodeling professionals, providing project management, estimating, and client collaboration tools. Adjacent to QB's internal tech stack and a potential partner or competitor depending on QB's go-to-market evolution.
