"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"The gentleman who came to do the work (Rudy) was friendly and punctual, but just didn't seem very detail-oriented or professional, and he didn't come to the job very prepared.
He came to install a skylight tube.  He went up into our attic and started working - and he cut a hole in our ceiling down from the attic without *measuring the dimensions* first.  After punching a big hole in the ceiling he realized he couldn't put the skylight tube there because there were framing members in the attic that restricted his access, and the skylight tube wouldn't fit but he'd already made a big hole there.  So then he asked to borrow our tape measure because he hadn't brought his with him (?!?).  After trying for quite some time to shave away the beams in the attic and make the skylight tube fit, he gave up and cut away the attic beams.   Finally he could have room for the skylight tube.  Except then he had to brace the beams in the attic to reinforce the area he'd cut away.  But he didn't have any materials in his truck that would work.  So again he asked if we had anything in the house he could use.  We scrounged around down in our garage and found some pressure-treated 2-by-4's that he cut & nailed & used to brace the beam cutout in the attic.  By his own admission they were the wrong size and the wrong material, but that's what he used.  When he was finished with the skylight tube installation, the area of the ceiling around the tube opening was cracked, smudged, gouged, and all-around pretty ugly.  We had no choice but to leave it that way until next time we repaint the ceiling, so it still looks bad even today. 
He also installed a solar attic fan, and he gave us a discount after all the adventures with the skylight tube.  A discount was nice, but I wouldn't hire him again.  Now I'm considering bringing in another contractor to repair the damage he did in the attic.

Skylights questions, answered by experts

Skylights increase natural light, improve ventilation, and enhance aesthetic appeal in rooms.

Common skylight issues include leaks, condensation between glass panes, damaged seals, and cracks in the glazing. Regular exposure to weather elements can lead to these problems, requiring timely attention to preserve the integrity of the skylight and the surrounding roof structure.

When planning out skylights and deciding how big they should be, it's important to look at the dimensions of the interior space. In addition to changing a room aesthetically, skylights influence the illumination and temperature of the space below. The U.S. Department of Energy recommends that a skylight’s size should never be more than 5% of the floor area in rooms with many windows.

Yes, you can replace a skylight without changing the entire roof—if the roof is in good shape. First, you need to make sure the roof around the skylight is intact and free of damage. Quality installation is crucial to prevent leaks, including replacing the flashing, which seals the skylight to the roof. While replacing the skylight alone is doable, it can make sense to replace both at once to streamline the work, coordinate the warranties, and reduce the risk of future leaks. If you’re unsure, reach out to a professional for help in deciding the best approach.

Leaks are the top concern for skylights, often due to improper installation or worn-out seals. Over time, water can seep in and cause major damage to your home’s ceilings and walls. Other common issues include condensation, which leads to mold, as well as physical damage from weather or debris. If they’re not sealed properly, skylights can also bring unwanted heat in the summer or cold in the winter, affecting your home’s energy efficiency and tacking on extra dollars to your bills.
