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

Yes, including recycled denim and cellulose from natural fibers.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Spray foam insulation can last up to 80 to 100 years, making your investment worthwhile over the long run. Closed-cell spray foam tends to have the highest durability. Open-cell foam is subject to moisture, which can lead to deterioration. Remember that some spray foams will damage plastic piping, so consult a pro if you have PVC or CPVC pipes.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.
