Show the crane pick above the rendering, because that is the doubt
The first screen should prove you can get equipment to the water, not that you can photograph it afterward.
Every city pool buyer arrives with the same private worry: there is no driveway, the passage beside the house is narrow, and the yard is only reachable through the parlor floor or over the roof. Nothing on a standard pool website addresses it.
Put the answer at the top. A photograph of a crane pick over a row house, a conveyor running out a side alley, plywood and floor protection through a hallway, and one sentence that says you build where trucks cannot go. Buyers who have been told no by two other firms will read the rest of the page.
Renderings still belong on the site. They belong below the proof, because a rendering answers a question the visitor has not reached yet.
Name the work you do not do as well. A firm that says it does not take on rooftop installations, or only builds where a machine can reach, loses inquiries it was going to lose anyway and gains credibility with the ones it keeps.
