"What an amazing job! I had a leaky skylight and had to replace it or the roof and considering my house is from the 1870's, a new roof plus new skylight seemed like the right choice. Arber from Landstar was very quick to give me a quote and schedule the work the next week! This, with snow on the ground and the holiday. His quote was fair, he was very responsive, and his crew were seriously hard working. I cannot recommend Landstar Construction more."

"The project manager for this project, Mike, did a super professional job. We had leaks from skylight windows in family room. He personally assessed the damage, created a staged repair plan and supervised the execution of those repairs.And his team apparently know what they're doing. The wind, rain of this weekend's Nor'easter were a big test. Genius Pro definitely passed. I highly recommend this contractor. 👍"

"Altin is the bestâ ¦ He came right away to give me a quote for the replacement of two skylights. He also followed up on the quote to see if I had any questions or if I was still interested in hiring his company. I just had a good feeling about him. Iâ m extremely pleased with the job he did and I will definitely use him in the future. Great craftsmanship and pricing."

"Brian and his team replaced my roof, gutters, installed gutter screens, and replaced rotted wood molding. They were professional and kept me informed on the progress of the job with pictures from their drone. They were not the cheapest but based on the excellent work they did repairing siding after a storm a couple of years ago, I selected them to do my roof. I may have them build me a new deck and repair my retaining wall in the future."

FAQs for existing skylight repair, replacements or sealing projects in Princeton Junction, NJ

Yes, skylights can heat your house. Skylights pull in plenty of sunlight, and that solar gain raises indoor temperatures during bright hours. The extra warmth is great in winter, but can feel stuffy in summer. Keep the heat in check with shades, low-E coatings, or reflective films so you enjoy the light without driving up cooling bills.

A newly installed skylight lasts for eight to 15 years when built and maintained well. Regular cleaning, prompt repairs, and removing obstructions such as leaves and debris help keep the unit in optimal condition. Consistent maintenance prevents premature deterioration and keeps the skylight operating safely and efficiently over its lifespan.

Several issues trigger skylight leaks. The unit may not sit flush with the roof, letting water sneak in, or the flashing and weather-stripping could be breaking down. Sometimes it’s just interior condensation that drips when the AC runs hard against humid outdoor air. A quick inspection tells you which fix is needed.

Replacing a skylight takes between three and five hours under straightforward conditions, with professional crews ensuring safe installation. Larger units, custom shapes, very high ceilings, or hard-to-access areas add extra complexity, extending the work time accordingly. Careful planning and expert handling guarantee a secure replacement process even when complications are present.

It is not safe to attempt skylight repair or replacement on your own because the work involves dangerous roof access, handling fragile glass, and managing a heavy frame. Expert professionals provide the necessary skills and safety precautions, ensuring that installations or repairs are performed correctly while preventing injury and additional property damage.
