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 FAQs, answered by experts

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.
