Our installation process

Every stage of the installation handled with care, precision, and professionalism.

    A free consultation by phone or in person to understand your requirements, assess your property, and discuss design preferences, budget, and timescale.

    Measurements & technical assessment

    Our team conducts a full survey for accurate measurements and to flag any installation challenges early. Thermal, ventilation, and security regulations all factored in.

    Quotation & proposal

    A clear, itemised quote outlining product options, installation timelines, and total costs—tailored to your needs and budget.

  4. 04

Our commitment

Sustainability & compliance.

Sustainability is embedded in everything we do. Our energy-efficient glazing reduces heat loss and lowers energy consumption. We work with responsible suppliers, recycle off-cuts, and adopt waste-reduction strategies across production and installation.

All installations comply with current UK Building Regulations including Part L (energy), Part F (ventilation), and Part M (accessibility). We are FENSA registered, providing certification on completion.
