"Brian, Bryan and Matt were our crew and were excellent. They were efficient, friendly and kind to me and my kids who liked to watch them work. The windows they completed look perfect. There was one window that they had to reschedule due to the space being very un-level. They ordered a brand new window and scheduled a new date to complete the job for the last window. They called as they were finishing up to explain everything. I also appreciated that I didn't have to be present for them to complete the job so that I was able to go to work."

Renewal by Andersen of Cranford, NJ is proud to serve the window replacement and patio door replacement needs of the Cranford area. We are the window replacement division of Andersen Windows, drawing on the Andersen tradition of over 110 years of quality, innovation and craftsmanship. Our turnkey process begins with a call from you and includes a respectful in-home sales consultation, custom-manufacturing of replacement windows to precisely fit your home and installation by a dedicated team of professionals. Best of all, we stand behind our products and installation with one of the strongest warranties in the Cranford window replacement business.

"1) Renewal by Anderson doesn't show up on time. 2) Renewal by Anderson doesn't provide correct instructions for the homeowner. 3) Renewal by Anderson cannot measure correctly. 4) Renewal by Anderson cannot install moulding correctly. I work from home and can't "stand-by" waiting for a crew to show up late. I had asked what had to be done prepping for their arrival and I removed all window coverings and shades and anything within 3 feet of the windows. Pets were secured. I was told nothing on the OUTSIDE had to be removed. Well I had to remove the 3 flower boxes from the OUTSIDE of the front windows. Two different people from Renewal by Anderson measured the windows but the oak moulding was incorrect. Take a look at the photos of when they finally installed the oak moulding. The windows from Renewal by Anderson are great...everything else they do is terrible."

Insulation questions, answered by experts

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

DIY is possible for basic rolls or batts, but professional installation ensures even coverage and efficiency.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.
