If it is required to match the wood finish with an existing wood floor we order stains from professional stain mixing companies and take due care to do a good job, but cannot guarantee that the finish will match perfectly.
Sometimes floors are made using technologies not available to us such as UV ray bleaching and certain wood species are not available (ex. European white oak). Alternatives, such as North American white oak in this example, may give a different finish. Even using different wood from the same tree type and forest may not match the finish perfectly.
If steps are “touching” the side wall, the side wall must be finished straight and plumb to achieve uniform and minimal gaps between the steps and wall. Walls should be constructed properly and we will not scribe the steps to fit into wall imperfections.
Metal portions of stairs that remain visible are powder coated or spray painted depending on stair design. Color as per customer request.
Metal in some types of stairs may be custom finished in stainless steel, black oxide, wood veneer or anodized aluminum.
