About us

Troughtons Builders (T.H.I Ltd), local builders for the Lake District, Cumbria, and the North West.

We are a local firm of master builders working in Cumbria, the Lake District and the North West.

Established in 1988, we are proud members of the Federation of Master Builders, with award winning projects that show our commitment to excellent standards on every building project.

We specialise in the restoration and refurbishment of historic properties throughout the North West of England but particularly in Cumbria, Lancashire and the Lake District.

Sympathetic extensions to traditional Lakeland buildings are a common part of our work, but we are equally well known as building contractors for new properties.

We work with a full range of local trades and skilled craftsmen, including general builders, joiners, plumbers, electricians, stone masons, plasterers and decorators. All of them are fully accredited with the appropriate professional body.

Our team has considerable experience of working on traditional restoration and refurbishment projects, and we can offer a full site management service for your project.

We work closely with architects and surveyors to get every detail of a build exactly right, and we can provide advice for planning purposes prior to work commencing.

Whether you are looking to secure professional, reliable contractors for renovations, refurbishments, extensions, conversions or new builds, we are happy to provide a quote.

  • Victorian terraced house

    We are delighted with our Victorian terraced house after a complete renovation by THI. It was a major job as the house had been neglected for many years, but the project was very well managed with minimum stress for us. It was carried out by a skilled workforce who were always polite and cheerful. Neighbours have commented on their considerate approach in minimising disruption to adjoining properties. We benefited greatly from the expert knowledge and advice of Jim and Paul, who were enthusiastic and careful to get things right, while keeping within budget. We would have no hesitation in highly recommending THI for any home improvements.
