Every job leaves a paper trail.

Twenty three panels across six roof mounted arrays, carrying a heavy layer of dust, pollen, and organic debris from a long stretch without a professional cleaning. Every array got two full passes, hand scrubbed with a soft head and a cleaner made for photovoltaic glass, then rinsed. Nothing abrasive touched the glass.

While we were up there, we documented four conditions. Four panels carry orange brown spotting that did not come off after two passes, so it was photographed and recorded instead of chased with harsher chemistry. Four arrays sit at a low tilt where rinse water collects at the lower frame edge. A gutter corner seam is leaking and staining the fascia and wall below it, and leaf and palm debris is packed into the gutter guard ahead of the rainy season. Tilt is solar contractor work, and the report says so plainly.

A loft fan on a vaulted ceiling would not change or hold speed at the pull chain. The fault traced to the three speed switch inside the housing, with corrosion on the pull chain right where it enters the switch body. A corroded chain binds at that entry and side loads the switch until it fails.

Power was cut at the panel and the fan confirmed dead before anything was opened, not left to the wall switch. The existing wiring was photographed and labeled before a single conductor came off, the new switch went in with every wire back in its recorded position, and the original chain was reused because it was still sound. The fan was run through all three speeds and off, and the light kit was confirmed working before we left.

The community manager engaged us to clear abandoned construction material from a gated association RV lot: galvanized pipe, steel fence posts and channel, loose metal stock, traffic cones, a barricade base, and scattered debris across the graded surface. Gate access was arranged in advance with the board contact.

Everything came out in a single visit. Metal was separated for recycling and the balance went to a permitted facility. The perimeter and the tree wells along the fence line were policed for small debris, and the lot was released the same day with no damage to fencing, irrigation covers, or the trees.

A four inch, roughly ten foot straight run through a side wall, rigid duct with a flexible transition at the dryer, and never serviced before this visit. The dryer was pulled, the transition was disconnected, cleaned, and reconnected, and the full run was brushed and vacuum extracted from the exterior hood through to the appliance end.

Readings were taken at the face of the hood before and after, same instrument, same position, same heated cycle. We did not convert them into a CFM rating, because face velocity at a hooded cap is not duct velocity, and the report explains why. The hood itself is a good design with no cross bar grille for lint to catch on, so it stayed. No parts were sold that the house did not need.

A hillside home with a continuous gray film across every array, heaviest along the lower third of each module where runoff carries sediment down to the frame. The film did not release on the first pass. There are two ways to answer that: push harder with pressure or stronger chemicals, which is how anti reflective coatings get damaged, or let the solution work and go back over the glass. We went back over it. Every module was scrubbed twice.

Tile was assessed before staging and the ladder set on a stand off so no load bore on the tile edge or the gutter. Glass was inspected for cracks, chips, and delamination before any water touched it. The cleaner was a photovoltaic formula at 1:500, the brush is reserved for module glass only, and the final rinse was purified water, top down, left to dry with no towel contact. Work started at 7:03 AM, while the glass was still cool.

A four foot run from a gas dryer to a grade level hood set low in a planter bed. It arrived restricted: 2.750 meters per second at the termination, roughly 47 CFM. The run was brushed end to end in two passes, the transition and hood were cleared, the damper confirmed free, and the gas connection left undisturbed. The same reading after service was 10.05 meters per second, roughly 173 CFM, moving the vent from restricted to clear on our internal standard.

The discharge temperature went up after cleaning, from 118.0 F to 126.6 F, and the report explains why rather than hiding it: a clear run finally moves the dryer's heat outside where it belongs. The same visit included a condition walk of the exterior, fence and hardscape, garage, pool surround, and accessible interior. Eight findings were photographed and ranked, three marked address soon where water and salt air keep working on the material. Nothing on the walk was priced on the spot.

An eight foot run terminating through a jack on a first story tile roof. The cap was found deformed open with its securing rivet gone, loose enough to lift by hand, and the duct throat behind it was packed solid with compacted lint. A dryer exhausting into that pushes heat and moisture back into the appliance and the cabinet, which is the condition most commonly associated with dryer fires.

Tile was assessed and photographed on a pre-walk before any weight went on the roof, and the ladder was staged on a stand-off so it bears on the fascia rather than the tile or the gutter. The run was brushed through from the roof with a drill driven brush while the dryer ran, so the loosened material carried out through the jack instead of into the house. The throat was cleared to bare metal. We came back two days later to seat the original cap and set a new rivet. No components were replaced and no tile was cracked.

The system was carrying a heavy soil band along the lower edge of every module, where runoff had been drying in place and leaving a mineral and dirt ridge at the frame. That band is the expensive one, because it shades full cell rows rather than scattered cells. Bird droppings and organic staining had collected at the upper edges of the main array.

Every roof plane was photographed before a tool touched glass. Modules were washed with a soft bristle method rated for photovoltaic glass and anti reflective coatings, no abrasives and no pressure washing. Frame edges were cleared so water sheets off rather than damming, then each plane was inspected for cracked glass, delamination, hot spot discoloration, loose clamps, and rodent intrusion under the array. Nothing was found that needed flagging. Recommended return is February 2027.

A four foot run with no elbows should move air freely. This one measured 470.3 FPM at the exterior termination with a discharge temperature of 127.9 F, which is what a heavily restricted run looks like. On a run that short, interval is the only explanation, and the volume of lint recovered at the outlet confirmed it.

The run was brushed end to end from the interior connection through to the termination, the lint expelled at the outlet was collected and removed from the site, and the transition duct was cleaned and reinstalled rather than replaced, because it was sound. The verification reading was taken at the same point with the dryer on the same cycle, so the two numbers are directly comparable.

Water damaged particle board under a utility sink, soft enough that the cabinet floor had stopped being a floor. The sink stayed in place and the new decking went in around it in sections, which is slower to plan and far less invasive than pulling plumbing.

Cutting out the failed panel uncovered two rodent nesting sites and a dead rat beneath it. The cavity was vacuumed out and cleared, the entry points were sealed, a cleat was installed for bearing, and a plywood patch was set flush and the baseboard reattached. Sanitizing was not performed, and rather than leave that unsaid, it was written into the report as a pest control item for the homeowner to schedule.
