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

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.

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.

The R-value is a rating that measures the insulation’s thermal resistance (in other words, how well it insulates). For most pipe insulation, the R-value will fall between one and five. The higher the R-value, the more protection for your pipes. All pipe insulation materials should have an R-value listed in the product description or on the product label.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.
