"Great quality work, paid attention to every detail; from laying down plastic to corner guards to cleaning up every last piece of insulation on the ground outside. The owner and his crew, who were his father and family friends were very professional and kind. The best owner and operator business that I would recommend to the next person in line."

"Technician Jake Sheiner came out for free inspection and estimate. Explained with the amount of blown-in insulation we already have that adding more would not net any energy savings. He was honest, polite and knowledgeable and did not try to see us something we did not need. He cleaned up after inspecting both attics and explained everything he found to us. Thanks, Jake."

"We have a 1970's and we decided to have an energy audit by Landmark Construction. It was clear that our house have some energy issues and was in need of a any type of energy overhaul.  The report that was prepared for us by Charlie and his office staff, was comprehensive, clear to understand and revealed that the ducts at the attic  was not sized appropriately. In addition to that, the furnace/AC in the smaller unit was old (and original) and had to be replaced. The recommendations that Charlie told us, included a new furnace/AC, new tankless water system, hot water pipe insulation, building sealing, the insulation and new ducting throughout the house. This was the best investment we ever made.  I could not believe the difference in our utilities bill.  Charlie and his team were great,  professional and experienced. I wish we did these 15 years ago!!

"After we returned home from our summer vacation out of town, we found that our master bath and bedroom had flooded due to rain and clogged plumbing. When I called the chief executor of Hometown Restoration, he replied quickly, provided a reasonable quotation, and started work straight away. We were delighted with the accuracy of the treatment of water, as well as the quickness through which his workers restored our master suite after insulation removal, flood cutting, and so on. Our home looked nicer than the original! Staff were professional, kind, and meticulous in their clean-up. I would refer Hometown Restoration to others!"

"Jim is amazing. We needed new windows for the bedrooms - the old ones were original from 1949 and no longer closed! Jim came over and helped walk me through the options. He also did a quick assessment of other areas where we might be losing energy efficiency and offered multiple solutions (some of which he suggested I could even do myself). The new windows are beautiful and keep the cold air out!! When I'm ready to order more for the other areas of the house and to insulate our walls, I will be sure to call Jim. He is very knowledgeable, friendly and believes in his work. It shows! Thanks Jim and Healthy Homes 4 U!

"I bought an Angie's list deal for dry wall repair but really they just spread some spackle on it and left it rough. I had to scrape off the blobs of spackle left on the ceiling. My boyfriend could have done the same job. I wanted them to actually replace the dry wall where it was cracking. Mainly they wanted to sell me more jobs and pushed me to sign on with them to get new insulation in the attic. I had them give me an estimate on rain gutters while they were here. Their estimate/prices are very high. I think they have to pay for all those people manning the phones. It sounds like a boiler room when they call."

Insulation questions, answered by experts

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.
