"We had them install all the roofing and other hardware for a full Tesla solar roof. Once that project was going, we also had them do 5 outer window/door projects for us. All went well and we're happy we had them do everything!"

"Edis with Skills in Construction was outstanding. He was extremely professional and his work was definitely high quality. He put together an extremely complicated playset like he was doing it for his own kids. He even went the extra mile to recommend and install a solid base so the set wasn’t wobbly on the almost level patch of grass. I have kept his number in my Phone book and will call him again."

"The owner was meticulous when performing the work on our porch renovation. Installed insulation on the ceiling and walls, ship lap on the walls, tongue and groove ceiling in a herringbone pattern. Installed a third electrical outlet. Painted an accent wall, trim around windows and door. Installed an exterior door and laid a new carpet. We couldn’t be happier with the results. We have more work around the house and will definitely be calling on Bluesky when we’re ready to move forward. Thanks to Roland and his staff."
