Dave and Martin did a brilliant job installing my porch. They were professional, polite and finished the job quicker than anticipated. The wrong handles accidentally arrived and they were straight on to order the right ones. I'd highly recommend.

I had my front of house windows fitted by the Father and Son duo, Dereks, from Senator windows a number of years ago. So I was delighted they were back to replace the remaining old windows. They showed the utmost respect to my home, and left me with fabulous new windows. The Dereks are worth their weight in gold.

Excellent job. Four windows replaced in four hours. Access to some was difficult but the job was accomplished by two absolute gentlemen and no damage at all to existing tiles, as can be seen from photos. The difference in heat retention is night and day. Would recommend Senator without reservation.
