"Jim was very prompt and seemed responsive. He is a nice guy who works hard.  He started the work when he said he would and kept it on schedule in spite of some difficult weather.   His brother worked with him the first few days, but after that he did all of the work himself. 
Unfortunately, the work does not look as professional as I had hoped.  Some of the wood is not cut straight, edges are not smooth, and there are many gaps between boards. 
As the work got toward completion I told him of my concern that the workmanship was not good.  Jim said he would get it all fixed up at the end.  He filled some gaps with wood filler and sanded them, but did not finish due to rain.  The filled and sanded joints still look sloppy.  Unfortunately, these joints are right in front of the kitchen window, where we see them all the time.
Jim said he has a lifetime guarantee on his work and will come back to finish this up.  I hope he will.
Another builder told me that the structural work on the deck is very good, even "overbuilt," which I was glad to hear.

Update: Jim came back and relaid some of the boards on the deck and it looks much better! I would definitely hire him again.

Update:  The second summer after Jim built the deck I stained it myself, so I got a close look at the workmanship. Many boards were split by nailing, decking is not spaced uniformly, and  joints are not well fitted. "

Insulation FAQs, answered by experts

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

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.

No, 55 degrees Fahrenheit is not too cold for a house, as it’s a temperature that will keep your pipes and appliances from freezing. Well-insulated homes can even go to 50 degrees, but check with an HVAC pro before opting for such a low temperature. Stick to 55 degrees to be on the safe side.
