"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

"The job was very well done. Gustavo and his crew were EXCELLENT. Dealing with the project Manager Taylor was EXCELLENT. One of a kind company. A unique feature that was used for installation was the inclusion of BOTH Sanford insulation and housewrap. I have not had another contractor offer me both of those. It’s always either one or the other. Home Genius is backed by the better business bureau and is a James Hardie certified installer for those looking for one."

"My bathroom remodeling experience was unexpectedly pleasant, and I owe a great deal of gratitude to the guys from Score Construction. I had a rough idea going in of what I wanted my mother's new bathroom to look like, but it was mostly just conjecture and hand-waving, needless to note I'm the type of guy who needs a gal that's mechanically inclined, because I'm far from it. Before starting the project, I had three contractors come and take a look at the bathroom (I also had two contractors who could only give me quotes over the phone, they were cheaper than the quotes I received in person, and I think it's very obvious why). They were all very professional in their conduct, but what set SCORE apart from the rest was their willingness to hear me out. I drew diagrams of what I wanted the bathroom to look like, and SCORE (in particular Janusz, though his partner was commendable as well) took the time to analyze my thoughts line by line. For my wishes that were feasible, they explained exactly how they would accomplish it, and for some of my ideas that were either too expensive or impossible considering the layout of the bathroom, they suggested revisions that were in line with the overall design (her bathroom is roughly 100 sq ft, so there was ample space for design). My only complaint about the other contractors was that they did not respect my ideas enough, not that they were rude in any way, but it felt to me as if the design was already established according to their desires, and it was me that was going to have to come around to their way of thinking. Admittedly, I have no design experience, but this is my project and my money so I figured that the hired hands should be a little understanding when it comes to my wishes. The guys at SCORE were more than understanding, and it showed itself in the final product. Once all the preliminaries were settled, the actual construction began and it was completed in two weeks. They adjusted their work schedule around my availability (if I was free and let them work straight w/o any days off I imagine it would have been done much sooner). They did a very professional job, and I'm very glad to have had such an easygoing remodeling experience. Mum's happy, so I'm happy. -Ali"

"Travis was,very reasonable, punctual and did the job very efficiently, leaving no mess behind. My family room wood floor is now insulated below in the crawl space, eliminating the previously cold floor we had before the insulation. The insulation also protects the wood floor by adding a vapor barrier. We are very pleased and would recommend Travis and Enviro Foam Tek."

"Attic Fanatics were easy to work with from the initial inquiry phone call. A thorough assessment of what was needed to be done in my attic was shared clearly and precisely. They addressed my concerns of health and safety and shared the full scope of the work. Upon prompt arrival to remove what was necessary they did a neat and clean job. I am so happy with the new insulation installation. They made my home feel better already! I would recommend them fully as they are kind and knowledgeable and do quality work."

Insulation questions, answered by experts

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.
