"We had radiant barrier insulation installed insteads of blown in insulation. It was laid in the attic rafters, upon the completion of the job the service provider could have done a better job of cleaning up. He also left some marking on our cabinet. When the gentleman came over to give us an idea of what radiant barrier is we never knew when he would be there, they gave us an estimate but then upon completion we wrote a check, but never received a receipt of payment, or work order showing completed work. All we had was the gentleman sign the estimate that we had been given two weeks prior to the job. And the installer did not have any paperwork saying that he did the job. But we had him write that on the estimate. I would expect more professional paperwork."

"Good customer service and were flexible when scheduling the work to be done. Can already feel a bit temperature difference in the attic where the insulation was done and the finish job makes the attic very bright. We have gained valuable space having had this work done."

"Since this remodeling was the first remodeling that we decided to do after a long time since we did our last remodeling that required to hire a contractor to do it. The kitchen that we wanted to remodel, need to includes the cabinets, floors, island, counter tops, hardware, paint and lighting. We also wanted to do as many energy efficient features that will help us reducing the bills during time. Our search was for high quality and low quality and reputable construction companies that can service my area. Landmark construction energy crew was the great find that I was able to talk to and hire. First off their service was top notch. They were very responsive from the first meeting we had, patiently and really wanted to know what I’m trying to do in the kitchen. They were in touch with me during the whole work and made sure to provide me with updates regard anything that was complete and what will be next. What I liked most was that they were extremely detail-oriented. I very much appreciated that, especially given the Major scope of my project and plans. The end results were more than I expected. All the low voltage lightings, the special insulation that they used, the extra protection that they installed in the window that I have in the kitchen and more… All of this features improved the energy protection at the kitchen. They followed up with me the following day after all the final documents were signed off by me about the work in order to make sure that I was happy with the final results. I'm happy to mention that kitchen remodeling project was completed a little bit before the due date."

"Joel at Quality Insulation is my first call for my insulation needs. We've done about 8 projects together and each time he is on time, efficient, and follows thru with what he says he's doing. Give Joel a call you'll be very happy. I've also referred him to a few friends and they've all been happy."

"Joshua has done a lot of work for us over the last year - from replacing blinds to fixing faucets, toilets and installing light fixtures, smoke alarms, shower fixtures, etc.  His work is always excellent!  He is very prompt, reliable, and does a thorough job.  I was thrilled to find such a great handyman since we had to move and rent out our house.  The only problem is that his schedule is very busy because he's so good!!

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."

Insulation FAQs, answered by experts

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.
