Building Success Through Hard Work

L and L Underground is a family owned and operated utility contractor located west of the Twin Cities in Buffalo Minnesota. Known throughout the industry to be very quality oriented, we ensure every job is completed with the highest of quality and attention-to-detail that is hard to find in this fast paced industry.

We started as a father and son team – both having worked for competing utility contractors. We found that the larger contractors had left a void in the marketplace for a small, flexible contractor that had great knowledgeable of the field, but small enough to be a one-on-one experience with the utility owners who wanted the job right the first time.

 Most of our early jobs consisted of farm water lines and automatic livestock waters placement and repair. Through hard work and honesty we have grown to include additional services: telecommunications (public and cellular), sewer, water, gas and also private utility locating.

Every employee is like a member of our family and we treat our customers, no matter how big or small, with the same outstanding commitment that their satisfaction is our number 1 priority. We pride ourselves on these values and know that they will carry us into the foreseeable future.

If you have any questions for us at L and L Underground please do not hesitate to contact us today. We look forward to the opportunity to work with you soon.
