We install end channels and then slide each strip of vinyl below it, then we add siding to inside corners of the exterior walls. The outside corners on the contrary are added after vinyl siding is fully installed. Once the work is complete our vinyl siding contractors will clean the area and present you with a warranty as assurance of the good quality of our work. If you are thinking about replacing vinyl siding or installing new vinyl siding – we are here to take care of your needs. Best Exteriors is one of the best vinyl siding companies in California, and we would love you to become our next happy customer. Vinyl siding is unique because it will enlarge and shrink depending on the weather, this is why when nailing each strip of vinyl we leave a little space between each nail and the siding to allow it to move a little bit as it expands or contracts. If it’s nailed too tight, vinyl siding might crack when expanding. Each strip of vinyl will be nailed using a specific set of wide end nails.
