Every project is unique, and pricing depends on a number of factors including your choice of timber, window style, quantity, finishes, and ironmongery. The best starting point is to get in touch and we’ll provide expert advice and a quote tailored to your project.
Devon’s varied architecture means there’s rarely a one-size-fits-all answer. Flush casement windows suit many of the county’s rural cottages and farmhouses, while sliding sash windows are more common in the Georgian and Victorian townhouses found in Exeter, Barnstaple, and Teignmouth. For listed or conservation area properties, we work closely with the relevant planning authority to ensure the chosen style matches the original character of the building.
In most cases, yes. Grade I, Grade II*, and Grade II listed properties will require Listed Building Consent, and depending on the scope of work, planning permission may also be needed. We have considerable experience navigating this process with Devon’s local planning authorities and conservation officers, and can support you through it from start to finish.
Timescales vary depending on the complexity, specifications, and quantity of windows involved. Once your designs are approved we’ll provide a clear production timeline, and installation (whether carried out by our team or a third-party installer) is planned to minimise disruption to you and your home.
