Pollmann & Renken GmbH

What Pollmann & Renken GmbH does

Pollmann & Renken GmbH is a privately held German fenestration specialist headquartered in Aurich, East Frisia, with a secondary showroom in Oldenburg. Founded in 1957 and operating under the motto 'grenzenlos wohnen' (living without limits), the company manufactures and installs made-to-order windows (plastic, aluminium, wood-aluminium), entrance doors (plastic, aluminium, wood-aluminium), conservatories and summer gardens, and terrace coverings — including a differentiated in-glass photovoltaic terrace roof range ('de Lüttje' and 'de Groot') with a 30-year performance guarantee. Aluminium profiles are produced in-house at the Aurich facility, while plastic and premium aluminium systems are sourced through partnerships with Kömmerling and Schüco. Supporting product lines include markilux awnings, Somfy motorization and smart-home shading, ekey dLine fingerprint access, insect screens, and an exclusive regional constila distribution line for modular waste-bin storage.

The business operates a regional, fully direct go-to-market model anchored by two physical Erlebnis-Ausstellungen (experience showrooms), at-home consultations by appointment, online configurators, a 360° virtual showroom tour, and a field-sales team of named advisors. All installation is performed by P&R's own certified fitters trained on a proprietary Qualitätshandbuch (quality manual) externally audited by an independent building energy consultant; this certification is the basis for guaranteeing customer eligibility for federal energy-efficiency subsidies of up to 20–25%. Revenue streams combine one-time project sales of products plus installation, recurring annual maintenance contracts, and spare-parts sales. Pricing is entirely quote-based; no public price lists exist, and customer acquisition is supported by a €50/€100 referral voucher program and an in-house subsidy-application service. The customer base is dominated by private homeowners in the Ostfriesland/Oldenburg region, with a small commercial segment including hospitality awning deployments.

The company is led by managing directors Silke Held and Gerd Bitterling, with Meenke Pollmann as Geschäftsführer. There is no parent company, no external venture or private-equity ownership, and no subsidiaries disclosed. Commercial register entry: HRB 158, Amtsgericht Aurich.
