They go the extra mile
“Had an issue with the weather for the last couple of appointments, which obviously can't be helped, the lads came today on thier day off and completed my new Velux as my old one was leaking really bad.
Really appreciate people going the extra mile”

Dumfries
Dumfries, a historic market town in southwest Scotland, offers a variety of property types—from traditional sandstone terraces and rural cottages to modern developments and period villas. In popular areas such as Georgetown, Locharbriggs, and Troqueer, many homes feature loft spaces, extensions, or darker internal rooms that would benefit from more natural light. Velux roof windows and sun tunnels are the ideal solution—bringing daylight into your home, improving ventilation, and increasing energy efficiency while enhancing comfort and style.
At Certified Installers Limited, we proudly serve Dumfries and the wider Dumfries and Galloway area as certified Velux installers and FENSA-approved professionals. Every installation we carry out is fully compliant with UK building regulations and completed to the highest standards. Whether you're installing a brand-new Velux window, replacing an existing one, or adding a sun tunnel to brighten a stairwell or hallway, our expert team provides trusted, regulation-compliant service throughout Dumfries. For quality Velux installations you can rely on, choose Certified Installers Limited.
