    I would not recommend for second time. I hired this company and for first time work was great and with all the before and after pic. But second time the service was done but provider did not give any after pics to confirm the job was done properly. This is after repeatedly asking and requesting and paying all the money. Not the best way to do business.

    These guys did a great job installing critter guard on my solar panels, but broke my roof tile. Got the run around, but never followed through with tile replacement.

    Had Hess and his associate install pigeon control siding around our solar panels after cleaning our roof of pigeon and bird droppings. After that they cleaned our panels and then cleaned the mess on the ground from all the stuff fr the roof. I was impressed with how they utilized a drone to capture before and after pictures of the roof showing the mess the pigeons nesting made. They also did a couple of extra tasks like repairing the chimney covers so that they didn’t have any openings. They were quick, efficient and very accommodating. I would recommend them to anyone. Our job was a full serv

    Juan did an excellent job cleaning my roof and gutters, cleaning the solar panels, and provided bird proofing for the panels. Juan is very professional to deal with and is very reasonably priced for the work he completed. I highly recommend him to anyone looking to get their solar panels or gutters cleaned as well as for bird proofing.

    Juan was really great. They cleaned up my roof and sent plenty of photos and videos of the before and after. They were quick to schedule as well!

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Warranty

    “clips that hook to your solar panels! Guaranteed ten-year lifetime! Solar Panel…”

Its website also mentions 24/7 availability, but not in a sentence we can quote cleanly.

Elsewhere

  • Google also lists this company under gutters.
  • It posts on TikTok, Instagram and Facebook. A page that stopped posting years ago tells you something a listing will not.

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

Who Google shows alongside them

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
