Construction Notifications - Residential - New Hampshire Gas - Liberty

Liberty is committed to maintaining and improving its infrastructure to continue providing safe, reliable natural gas service to our customers. During the 2026 construction season, Liberty will complete infrastructure upgrades in the neighborhoods listed below.

In addition to Liberty personnel, qualified contractors, including R.H. White Construction and Midway Utility Contractors, may be working in your area on Liberty’s behalf. As part of this work, all customers located along the construction route will experience a brief interruption in natural gas service while existing service lines are connected to the new gas main. In some cases, upgrades to the gas service line serving your property may also be necessary.

If your service will be interrupted or additional work is required at your property, Liberty or one of our contractors will always contact homeowners in advance to provide more information and schedule the work.

After work is completed, Liberty or the contractor completing the work will do their best to restore the property to its original condition.

We appreciate your patience and understanding as we complete these important system improvements and apologize for any inconvenience this work may cause.
