FAQ

Q: How much does it cost to install a skylight in Suffolk County? Most skylight installations range from $X,XXX to $X,XXX per skylight, depending on the model, size, ceiling type, and whether you choose a fixed, manually-vented, or solar-powered electric skylight. We give you a detailed written quote so you know exactly what you're investing.
Q: How long does installation take? Most single skylight installations are completed in one day. Multiple skylights or vaulted ceiling installations may take longer. We'll give you a clear timeline before we begin.
Q: Will my skylight leak? Not when installed properly. Leaks happen when skylights are installed by general handymen who skip proper flashing and sealing. We use Velux and Supreme manufacturer-approved installation methods on every job, and we stand behind our work.

  • Fixed skylights don't open — they're the most affordable and let in light only.

  • Solar-powered electric skylights open with a remote control and may qualify for the federal 30% Residential Clean Energy Tax Credit.
Q: Do skylights qualify for tax credits? Yes — Velux solar-powered fresh-air skylights and certain other Energy Star-rated models may qualify for the federal 30% Residential Clean Energy Credit. We'll let you know during your consultation which options qualify. (Confirm specifics with your tax advisor.)
