This was my second time using this company for a fence install and they did not disappoint. From the quote all the way through the fence install, they were very prompt, professional, and done an excellent job.

Their name says it all. They were the only company that was willing to give me a basic quote over the phone so I had some idea of pricing. The other two companies I received bids from were much higher-priced for the same service, and tried to upsell products and repairs I didn't need. Always...

Doorbell Installation questions, answered by experts

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

Reduces energy costs, improves comfort, and prevents ice dams in winter.
