Hertswood Joinery – Our Sister Company

Timber is a natural insulator that absorbs and retains heat with ease. Other than uPVC, wooden doors offer the best performance in terms of thermal insulation. Utilising timber sourced from sustainble forests and able to achieve outstanding A+ energy ratings, our timber doors are enhanced further with insulated glass units from SafeGuard Glass and Glazing for complete peace of mind.  Our range of windows, doors and conservatories are also available in hardwood, softwood & Accoya; all manufactured and supplied by our sister company Hertswood Joinery.  These products ranges are available to view in our showroom on Leeds Road.

    I’ve just had my windows and door done by Colfax and they have been great from start to finish. Shaun the fitter did a fantastic job and everyone at the office is always incredibly helpful on the phone. The men who came to measure and quote where also very helpful and honest. Thankyou.
