Garage Conversion to Home OfficeSt Albans, Hertfordshire

The removal of the central brick column, the insertion of a steel beam, and the fitting of a powered sectional door. Several companies’ website appear to offer a complete service but SDM were the only company I found actually doing so. Out of the 3 quotes I received SDM were in the middle – but I had zero confidence in the cheapest quote. Scott and his team were knowledgeable, hands-on, polite and friendly. Their work standard was excellent, and everything was left clean and tidy. As such they are good value. I would not hesitate to use them again or to recommend them.
