Small jobs welcome

I graduated from Maine Maritime Academy and currently do have a day job but am looking for some side jobs for extra money. I built an addition on my house and found that I have quite a bit of talent in all areas of a house. I’ve installed my own heat pumps in my home, I’ve poured slabs, did all of the plumbing, electrical, insulation, drywall, flooring, trimming, doors etc. I learned a great deal and would like to put that knowledge to use.

"Job started a day later than scheduled due to their equipment being down. Job was originally scheduled for 5-7 days. Job actually took 2 weeks and salesman called into the third week saying the job was done. We have never had mold remediation done before and was selling our house. The explanation of how the job would go was vague at best. This is not a process we are familiar with having never been through it before. In the estimate there was a blanket statement of “any construction materials removed will not be replaced” (once again we were never explained anything about this process in regards to things being removed). Upon the job being completed the buyer noticed there was no mention of insulation replacement. We were 2 days from closing and had to hire someone to replace the insulation. The handyman hired to replace the insulation noticed other items had been removed by octagon. We were not left a list of items removed from the residence. I was just told by Matt Brown that “that’s why I gave you a referral of a weatherization company” for 8300$ one would think you might get a verbal explanation of items needing replacement or at least an itemized list. Hope we don’t need to go through this again because as Octagon will not be contacted again."

Insulation questions, answered by experts

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

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.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.
