"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! ."

"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."

"I found Score Construction on Home Advisor's website. I was looking for a contractor and needless to say I read reviews for many of the construction firms. Every review I read was terrific for Score Construction and because of that I called, met Janusz Z who is the Owner and was very impressed with his knowledge and professionalism. I started with 2 bathrooms that were necessary to do because of water damage. I was thrilled with the work done, the care of how it was done by the workers that were both professional and respectful. A year later a major renovation for my apartment was considered and I called Score Construction. Not only did the renovation to my apartment turn out fabulous and I'm happy every day that I wake up and see how beautiful it is, but they also did major work to the outside of our building - replacing the cornice, roof repair, pointing of bricks, structurally reinforcing all 16 windows which was no easy task for a 100 year old building, but they got it done. ALL this work again was done professionally and with the utmost of care and the knowledge of how to get the job done is their forte'. Every experience that I have had with Score Construction workers and owner, Janusz Z has been top notch. I recommend Score Construction HIGHLY. You will be extremely happy that you did so."

"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."

FAQs for insulation service projects in Glen Cove, 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.
