Eruv Consulting

Rabbi Yosef Gavriel Bechhofer

author, The Contemporary Eruv: Eruvin in Modern Metropolitan Areas (Feldheim).

Both the construction and the maintenance of urban and suburban eruvin entail complexities and complications. Numerous issues arise in the design and in the building of an eruv. Just as many issues arise over time in the ongoing upkeep of an eruv.

With siyata d'shmaya, my sefer, The Contemporary Eruv: Eruvin in Modern Metropolitan Areas, has achieved widespread acceptance, and its standards have become normative across all segments of the community of Shomrei Shabbos.

Please contact me as soon as possible to schedule a consultation and an on-site inspection.

References and suggested compensation available on request.

I look forward to work together with you in enhancing Shemiras Shabbos.
