"Dealing with O'Brien Brother's Construction was a absolute pleasure from start to finish. The job consisted of removing and replacing a 30x30 vented skylight, new water & ice shield installed along with matching the existing shingles. The job came out great. I highly recommend this company for your next job."

"I recently had a skylight repaired and a small new roof installed, and I'm very satisfied with the work. The team was professional, punctual, and respectful of the property throughout the project. The skylight no longer leaks and looks great, and the new roof section blends in perfectly with the existing structure. They explained everything clearly before starting, provided a fair quote, and completed the job on time. Clean-up was thorough, and I appreciated their attention to detail. I’d definitely recommend them for both small roofing jobs and more specialized repairs like skylights"

"Alban, Barry and crew dismantled my existing, deteriorating chimney, only to find the original flue collapsing inside. Alban explained to me the severity of the issue and recommended a full rebuild with a stainless insert. While doing the job, they took care not to damage any landscaping and put down tarps to collect the debris. When finished, my property was clean and I had peace of mind. Thanks again HOME TEAM CONSTRUCTION!"

"Sami was very professional and completed the job quickly. He communicated often and showed up early on the agreed to day. He covered my furniture and rug to prevent any damage when he replaced our den skylight. He installed a new skylight, replaced shingles, and repaired flashing. He cleaned up any debris before leaving. Workmanship looks good."

FAQs for existing skylight repair, replacements or sealing projects in Uniondale, NY

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.
