Keith Lines Construction Ltd is a County Durham-based building firm with expertise spanning the full breadth of construction work. Under the leadership of Keith Lines, the business has built a strong reputation for delivering quality results — whether that's a new family home, a major renovation, or below-ground utilities work.
Our utilities division is a particular point of difference — installing gas and water pipes and electric cable ducts, from excavating the ground to fully reinstating the surface. This capability makes us a one-stop contractor for developers and commercial clients alike.
Every project is delivered with the same high standard — from a small renovation to a full new build or utilities contract.
Building works and utilities installation — two disciplines, one reliable contractor.
