"The type of work I needed done was literally beyond over 12 other companies I had to my home for an estimate. Some very popular companies (which are supposedly experts) at cleaning up the situation I had in my basement. The situation: Foam Insulation that was sprayed in all the Wellâ s / Between All Jointâ s through out the entire basement of a 3 Bd Rm Ranch. The Foam HAD to be removed due to Termites. All Exterminatorâ s stated the Termiteâ s could not be treat until the Foam was removed. To my complete surprise and obvious delight that they took the job was beyond wordâ s. Some very (as they stated) were the best â ¦ yet some actual stated; â Ummm -,I never seen this nor been ask to remove it.â One company wanted $250 for the first hour and $150 for each additional hour - with a quote of taking 3 dayâ s to complete the job. The estimate for the job never exceeded more than 1 day -,there was no surprise or statementâ s that it was an impossible job to do. They arrived on time - - took 2 / 10 minute breaks and completed everything within only several hours. I was absolutely amazed and thrilled. Professional and completely committed to finish the work. I absolutely recommend if your in need of anything foam insulation. Even removal. Iâ m extremely happy with the work and the professionalism. An absolutely top rated company and recommended if you need anything foam insulation related you to look no further. Thank you so very much for all the work you did! ."

"I wasn’t sure what to expect with getting new insulation, but Vantage Home Works made it super easy. They were friendly, showed up on time, and got it all done faster than I thought. The house feels warmer during the cold months and now with summer here the house feels cooler. I wish I’d done it sooner!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

FAQs for insulation service projects in Old Bethpage, NY

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
