      Why choose GT Carpentry?

      Quality And Skill

      Quality and skill are two of the main reasons our customers would never consider anyone else. Project timekeeping is very important to us and speed and accuracy are goals we set for every project. The sooner we can complete your project fully, the sooner we can get you back to your new and improved lives.

      Honesty And Transparency

      We are true to our word. We provide clear and itemised quotes that are easy to understand and we pride ourselves on delivering a friendly and reliable service always. When we price a project we'll stick to our quoted timelines and if we do run over, there's no extra charge. (Unless of course you'd like us to do more!)

      Cleanliness And Efficiency

      When it comes to cleanliness, we're in a class of our own. We know how important your home is to you and we treat it as it should be treated, as your castle, your mecca, as your children's world. It's often been said to us that we've left the place cleaner than it was before we started. It's a point of pride for us and one we take very seriously.

      Frequently Asked Questions

      Can we see some of your previous work?
      Absolutely! Our goal is your peace of mind so we let our customers and our past work do the talking for us. If you’d like, we’ll get in touch with our previous customers who have had works done that are similar to yours, let them know you’ll be calling and give you their contact details so you can speak to them directly.
      Can you help us make sure we maximise our natural light?
      Everyone needs natural light. It makes you feel better, opens up your spaces and makes your living areas liveable places you want to spend your time. We’ll look at the position of your house and where gets the most light at different times of the day and we’ll advise on the positioning of all windows, doors, roof windows, and glass units to maximise your natural lighting.
      Will your work disturb our neighbours?
      All of our team and the subcontractors we work with are very conscious of making sure we don’t disturb your neighbours. We understand that you have to live with them long after we’re gone and we do everything in our power to make sure that we don’t do anything to make them unhappy.
