"We have a complete building service from plans to completion — and a specialist division for utilities work."
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.

Based in Stanley, County Durham, we work across the region and know it well. Our reputation is built locally, through honest work, fair pricing, and keeping our word on timescales.
You'll always know what's happening on your project. We keep clients informed at every stage, from initial plans through to completion — no surprises, no guesswork.
We take pride in every job, regardless of size. The right materials, the right methods, and a standard of finish that we're happy to stand behind long after the scaffolding comes down.
We'll visit your site, understand your requirements, and provide a clear, itemised quote — completely free of charge. No pressure, no commitment until you're confident in your decision.
Alongside our building and utilities divisions, Keith Lines Construction holds specialist accreditations that set us apart from the competition.

Don't just take our word for it — here's what our clients have to say about working with Keith Lines Construction.
Structural alteration to home, knocking down an external wall and installing a large RSJ ready for bifold doors — including moving an external soil pipe and radiator. Reliable, excellent workmanship, safe, clean and tidy, nice people and competitive price. Clearly very experienced with this type of job. Highly recommend.
You've been doing work for us for over 20 years. House build, pool extension, laying flag stones, plastering, building outside stone walls, full drive, water feature including ponds and now a barn conversion — the list goes on. You're the best, Keith Lines Construction.
