    Frequently Asked Questions

    Yes. Although we're based near St Austell, we work across Cornwall and cover Launceston and the surrounding North and East Cornwall area. This includes communities such as South Petherwin, Lewannick, North Hill, Altarnun and Boyton.
    That depends on the character of the property. We offer options including casement, flush casement and sash-style windows, alongside different colours and finishes that can provide a more traditional appearance. For listed buildings or properties subject to specific planning restrictions, the relevant permissions should always be checked before replacement work begins.
    Absolutely. Many homeowners choose to replace several products at the same time. We can quote for a combination of windows, composite or uPVC entrance doors, French doors, patio doors and other glazing, giving the exterior of your property a more consistent finish.
    Replacing older or poorly performing glazing can help reduce draughts and heat loss. We can talk you through our energy-efficient uPVC and aluminium window and door options and recommend suitable products based on your existing property and what you're looking to improve.
