"I'm very satisfied with the quality of work this company does and the price was very fair. Aaron, the owner, was easy to talk to and after a short discussion, he knew exactly what I wanted. Mike and Dan did the insulation and even replaced a few floor boards at a nominal cost. They politely answered all my questions and you could tell they enjoy their work. If you want a professional job done at a very reasonable price, I would definitely give G.E.G. Enterprises a call."

Customers say: Quick response

"I highly recommend this business. I recently moved to the Lancaster area after purchasing a house that was built in the early 50s which needs some overdue maintenance. The attic insulation was old, worn out, and installed incorrectly. King Conservation gave me an estimate I was happy with and I agreed to having them do the work. They came in and air sealed the attic, removed the old insulation that was not needed, then installed new insulation properly. The team that came in were very professional and did a great work. I am very happy with the difference it made with the warmth in my house. I will definitely have them back to work on my basement insulation. 5 Stars!! Thank you Casey and the rest of the crew."

"I was very impressed with Fabiano Construction and the pro who did the work at my home. They replaced my stairs and handrail! The pro was so friendly and genuinely cared about the job he was doing. He was very professional and his work was impeccable! He was neat and cleaned up along the way. He answered all our questions and never acted like we were disturbing him. I would recommend this company to perform all your construction projects! They are a 10!!"

Insulation questions, answered by experts

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.
