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

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise.
