"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."

"I needed the attic of my 2 car garage insulated as well as some exterior wall on the main level. The job was done in one afternoon, including installation of Geeenrock on the lower level. Everything is buttoned up neatly and tightly and it is now easy to warm the space with a small heater. I would definitely recommend this company! Their cost was 1/3 the cost of the batt insulation alternative I researched and result is exactly what I was hoping for. Gary Centerport, NY"

Insulation questions, answered by experts

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.
