Hear from our Clients


Adam and his team do the work to the highest level and will not stand-down until everything is done. Nothing can stop them. Adam is a very professional and extremely reliable person who demonstrates strong passion for his job. I can highly  recommend him and his company, WA Building System Ltd, to anyone considering renovations and conversions.



Adam and his team carried out the work as described, plus extras, on time and as quoted. They worked with care and consideration and were careful to leave the house clean and tidy at all times. A reliable team I would have back when any further work is required.



Adam and his team provide a top-class service and they are extremely skilled in their respective fields. I have used WA Building for many years on large and small projects and have always been very impressed with their workmanship. They clean-up thoroughly when they have finished and never leave any trace that they have been on site. I cannot recommend them highly enough, whatever the job. Best workers I have ever had.
