My second installation with PSW was as smooth and professional as the first. I have also recommended PSW to three others, who also were extremely satisfied with their systems and the service provided by PSW. Richard Oliver and his team work hard to ensure good aesthetics from the install and leave the site spotless, after installation. Penny-Lee Griffiths can be relied on to ensure that the whole process is efficient and pleasant for the client. I recommend PSW without hesitation.
