What -Baubiologe Baldermann UG (haftungsbeschränkt) does

Baubiologe Baldermann, operating as a sole proprietorship (Einzelunternehmen) under founder Karsten Baldermann, is a Germany-based single-practitioner building biology (Baubiologie) consulting firm registered in Markt Schwaben. The firm provides on-site environmental measurement and assessment services for residential and commercial indoor environments, identifying potential health-affecting factors such as electromagnetic fields (Elektrosmog), earth radiation (Erdstrahlen), water veins (Wasseradern), global grids (Hartmann/Curry), geological faults, rock fractures, and indoor pollutants (VOCs, SVOCs, MVOCs, mold, asbestos, PAHs, wood preservatives).

The technical core is a suite of professional-grade calibrated measurement instruments from Gigahertz-Solutions (NFA 1000 data loggers, ETC 3951 A field strength meters, HFE59B and HFW35C high-frequency analyzers, FF6E frequency filters), Rohde & Schwarz (FSH6 spectrum analyzers), and Kleinwächter (EFM 120 electrofield meters), supplemented by digital multimeters and a Wünschelrute (dowsing rod) for water-vein and earth-radiation detection. Sampling for pollutants follows VDB guidelines, relevant VDI guidelines, and DIN regulations, with samples sent to quality-assured laboratories. The core product, Schlafplatz- und Hausuntersuchung, is priced at €298 incl. VAT and includes a detailed measurement protocol, an interference-zone inventory, remediation proposals, and a follow-up control measurement; complementary services such as Brunnensuche (€298), workplace investigations (€498), construction accompaniment (price on request), and pollutant testing (price on request) extend the portfolio.

The firm operates a direct-to-consumer field-services model: the practitioner travels to customer sites across Germany, Austria, Switzerland, and Luxembourg at all-inclusive flat-rate pricing, with bookings originated through the website, phone, or WhatsApp, and converted via a free initial telephone consultation. Demand generation relies on organic search presence, an educational FAQ, social media profiles on Facebook, LinkedIn, XING, and Twitter, and word-of-mouth referrals. A Berlin-based in-person seminar line (two-day Grundlagenseminar and Praxisseminar at €640 each, capped at 6–12 participants) diversifies revenue and builds brand authority. Founded in 2006, the practice reports 15+ years of practitioner experience and 600+ completed well-finding assignments, and is positioned as an independent diagnostician that does not sell shielding products.

Others

• Feng Shui Berater Deutschland (Verband): German professional association of Feng Shui consultants. Baldermann's services integrate Feng Shui consultation for workspace and construction accompaniment, placing him in the same ecosystem as certified Feng Shui consultants; relevant for partnership and referral dynamics.
• Wenning GmbH (Schirmung): Manufacturer and retailer of shielding products for EMF protection. While not a direct competitor in measurement services, it operates in the same customer purchase journey and Baldermann explicitly distances his practice from such product sales, making this an adjacent/ecosystem competitor.
• Verband Baubiologie (VB): Professional association for building biologists in Germany. Acts as a governing body and quality standard setter rather than a direct competitor, but membership confers customer trust signals that affect the competitive landscape for practitioners like Baldermann.
• Gigahertz-Solutions GmbH: Leading German manufacturer of professional EMF measurement equipment used by Baldermann (NFA 1000, HFE59B, HFW35C, FF6E). Functions as an enabling supplier and ecosystem anchor; also offers measurement interpretation guidance and training that competes for customer attention.

Direct peers

• Baubiologie Maes: Long-established German Baubiologe practice offering residential building biology, EMF measurement, and pollutant analysis. Direct peer in scope of services, certifications held, and target customer segment; comparable in service catalogue (sleep place and home investigations) and pricing structure.
• Biologa Danell: German Baubiologe practice offering building biology consultations, EMF measurements, and pollutant analysis for residential customers. Direct peer in service mix (sleep place, home, workplace) and in operating as an independent practitioner for B2C customers in Germany.
• EMF Beratung / EM-Stress: German EMF consultation practice offering measurement and assessment of electromagnetic fields in residential and commercial settings. Direct peer in target market, professional EMF measurement focus, and B2C service model; overlaps with the Elektrosmog offerings of Baubiologe Baldermann.

Broad incumbents

• Eurofins Consumer Product Testing Germany: Large international testing services group with German laboratories performing indoor air quality, VOC, asbestos, and pollutant testing — the same laboratory analysis Baldermann outsources for his Schadstoff- und Innenraummessung service. Functions as a broad incumbent in the underlying lab testing category.
• Institut für Baubiologie + Nachhaltigkeit (IBN): The leading German institute for building biology, which trains and certifies Baubiologen and publishes building biology standards. Functions as a broad incumbent and industry body whose member practitioners (including potentially Baldermann) compete in the same field; also operates a practitioner directory that influences customer referrals.

Regional players

• Baubiologie und Umweltanalytik (various regional practitioners): Regional German Baubiologie practitioners and consulting firms operating in specific German states with comparable service portfolios (home visits, EMF measurement, pollutant testing). Adjacent competitive set that customers typically consider alongside Baldermann when searching for a local practitioner.
