Excellent from start to finish, we had an internal door fitted between a conservatory and the kitchen, had to have the hinges adjusted after about 2 years. The service call was next day, problem solved. All very efficient and polite.Many thanks.

Top quality and highly professional service from initial enquiry to having the work undertaken. We chose Infil to install a new back door and to replace our old conservatory. We are absolutely delighted with the end result and would highly recommend the company if you are looking for new doors, windows or a conservatory.
