Frequently Asked Questions

Most frequent questions and answers

We cover the whole of Cornwall and most of Devon, if you can’t see your actual town listed, dont worry, chances are we cover that area, but to be sure just give us a call or use the contact us page.

We do cover the whole of Cornwall, we supply and install uPVC windows, doors, and Conservatories in every town in Cornwall.

We supply and install windows, doors, conservatories, replacement conservatory roofs, and cladding throughout all of the areas we cover. If in any doubt please get in touch.

We would need to inspect the existing conservatory to make sure that the frames are reinforced and that the base and footings are adequate to take the extra weight of a replacement conservatory roof, but it’s usually fine in the majority of cases. We take the old roof off completely and install one of our replacement conservatory roofs.

The Durabase base and walls system comes with a manufacturers 25 year guarantee.

The short answer to this is no! Under no circumstances should you put anything on a conservatory roof other than a like for like replacement. When conservatory roofs are engineered, they are made to be lightweight constructions with a weather loading tolerance, even adding insulation to an existing conservatory roof is dangerous and could result in serious injury or worse.
