"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."

"Juan came out and gave me an estimate for the work and exactly would be done. I didn’t actually have the work done for another two months but I was happy that they honored the previous estimate. I had to break my payment down some cash and some on credit and that was not a problem. Now even with the window open to ventilate the space it is noticeably warmer. I will definitely be using this company for any future insulation projects."

Insulation FAQs, answered by experts

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.
