No mystery to it. Here is exactly what happens from the moment you call to the moment we hand the job back.
Perimeter and heights measured, and the park's or jurisdiction's requirements for material, ventilation area and access confirmed before ordering anything.
Old skirting out, debris cleared, and the underside of the home inspected. Better to find damaged ductwork or a plumbing leak now than to seal it back up.
Top track fixed to the home and bottom track set to follow grade, with backing where needed. Getting this level and true is what makes the finished result look right.
Panels cut to the varying heights and set with the manufacturer's expansion gap. Vinyl needs room to move; installed tight it buckles in summer heat.
Vents distributed around the perimeter rather than clustered, access door fitted where plumbing can actually be reached, and trim finished at corners.
None of this is required — it just makes the visit quicker.
