Joinery & Building Contractors from Penrith

We are a family run company who have been in business for 40 years. We specialise in carrying out work for the individual, especially in peoples own houses, offering quality workmanship at affordable prices.

We cover all trades working alongside specialised workmen for those jobs we don’t do ourselves i.e. Electrical, Plumbing & Heating Engineers.

This way we can take on full contracts & offer you a continuity of work ensuring that jobs don’t drag on & on.

When you get in touch with Renwick Bros someone from the business will speak to you personally & deal with your inquiry, following the job through from start to finish.

If you do decide on us for your work, we will offer you a start date and turn up on the date agreed; more importantly, stop on site until the job has been completed.

We deal with the personal side of things – you can feel comfortable with us working in your home, as we treat everyone’s house as we would our own.

  • From putting a new lock on your door, to a full £100,000 home extension – No job is too big or small.
  • We take great pride in our work; however we are more than happy to return if you are not fully satisfied with any work we carry out.
  • All our operatives are fully qualified tradesmen ensuring our customers peace of mind when using our services.
  • We have public insurance of £5,000,000, ensuring our customers peace of mind when using our services. Click here to see our Public Liability and here for Employers Liability.
