Our complete new windows and doors comply with Document L Building Regulations. New sashes, casements or doors fitted into their existing frames do not have to comply as this type of work is classed as refurbishment and does not require certification. Listed buildings and some properties in conservation areas are exempt from Document L, and your local authority planning department will be able to advise.

Timber’s beauty comes from the fact it is a natural material, and as a natural product some degree of movement in terms of expansion/contraction can be expected. However, with the timber that we use, this movement is kept to a minimum.

Low quality timber windows can warp over time, however, DBJ wooden windows are engineered to add strength, eradicate knots and resist twisting also we are confidently able to give a Comprehensive 10-year guarantee on all windows and doors.

We use 4 layer weathershield paint and stain finishes on all of our timber products to keep them looking good, however timber products aren’t maintenance free and will require regular maintenance to maintain the performance and look of the product. The regularity of maintenance will depend on the location of your property and where the wooden windows are located on the property. Our paint finishes will require maintenance every 3 years to 4 years in a moderate climate (non-coastal areas at low altitude) or every 2 to 3 years in extreme climates (coastal areas and high altitude). Our stain finishes will require maintenance every 2 to 3 years in a moderate climate (non-coastal areas at low altitude) or every 1 to 2 years in extreme climates (coastal areas and high altitude). Unsheltered windows will require more maintenance than those sheltered or partly sheltered. We recommend that the surface coating is inspected annually and if required you should re-coat the wood with stain or paint.
