We stock common steel panel sizes and gauges on the truck, but we don't carry every insulated profile or laminate finish that showed up in Heathrow's developments through the late 1990s and early 2000s - some of those runs are specific enough to a builder-era door that we have to source them from the manufacturer rather than pull one off the shelf. With about 3,026 households in Heathrow against roughly 175,363 across the whole service area, it's not a volume that justifies stocking every discontinued profile locally, so we carry the common widths and order the rest.
That means a straightforward steel panel swap can usually happen same-visit once we've confirmed the fit, while a specialty insulated or wood-grain panel sometimes means a return trip after the part comes in. We'd rather tell you that up front than promise a one-stop fix and miss it.
