Welcome; a little about me. My name is Nick, I've been in and out of the construction world for the better part of the last 15 years doing everything from footings, foundations, and flatwork concrete through finish carpentry and paint. I am well versed in vinyl flooring, tile, drywall, roofing and siding, interior or exterior paint, pest exclusion, remodel and renovation, framing, monoslabs and finish concrete, windows and doors, and many more. During this time, I also attended college for architectural design and development. I have recently decided to stand on my own with the possibility to grow something for the future for my children who all want to learn the trades as well. I am available for quotes and am willing to work either at time and material or bid by the job. I will be uploading and adding pictures of recent work to include the project I am currently working on, which is exterior paint of 140,000ft in grey&black. Although I live in Oxford, ME; travel for work isn't and has never been an issue. I am competitive on pricing and available to work around a budget. The work performed by me can be billed out at time and material or an overall bid cost to suit your financial needs.

Insulation questions, answered by experts

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.
