Pretty much. You could take it a step further in your actual blog page and link the keywords you have here, "We can clean many different kinds of substrates & structures including concrete, exposed aggregate, painted, patterned, stamped & sealed concrete, brick, vinyl siding, aluminum siding, wood, metal, canvas, asphalt shingles, roof tiles, metal roofing, ceramic tiles, pavers, fences, stairs, gutters, houses, mobile homes, awnings, cars, trucks and other vehicles, boats & other water vessel, driveways, drive thrus, parking lots & garages, sidewalks, buildings, anything!?
If you had an independent blog page of all of your keywords on your website, basically the substrates you work on it would give everything a more solid boost. Gallery pages are good to link to also.
