"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

"Climate Masters has always provided top quality service at a reasonable price. They arrive on time and they don't find "hidden charges" or try to claim something needs to be replaced when it does. They are a great company to use"

"The work was done well and they cleaned up behind themselves, removing all garbage associated with the project. I expected that I would need to be responsible for the disposal, however they packed everything up and took it with. This young man is on the rise. I will hire him in the future as well as recommend him to everyone I know in need of electrical services."

"When we bought this house we were planning to renovate the basement.  The previous owner had represented that it had never taken on water.  The first weekend we were here, however, a torrential rainstorm caused the basement to flood.  We realized we needed to waterproof it before we could do anything else, and decided that drain tiling was the safest way to go.
Greg was phenomenally responsive from the start.  He was very clear about what needed to be done and how they would do it.  He also described some optional work but was explicit that it was optional and if it didn't fit within our budget that was that, and he wasn't going to push it the slightest bit.  His quote blew away the bigger, well-known firm and was less than or on a par with some others.  He also agreed to demo the walls for a slight extra charge, which otherwise would have been a huge convenience for us.  Between then and the start of work I emailed him repeatedly with various questions and he responded almost instantly.  When his workers took down the paneling we got the unpleasant news that we had huge cracks in the walls that would need to be tuckpointed and in one area a big chunk of foundation was jutting from the wall.  That section of the foundation would need to be replaced and a support beam installed.  We were more or less at Greg's mercy at this point -- we weren't going to halt work and bring in a series of guys to quote the tuckpointing & repair -- but Greg gave us an estimate of $2,600-$3,000.  We can't know for sure, but suspect that this price was more than fair, and Greg stuck to it even though we think the work turned out to be more than they expected.
The project manager, Jim, was fantastic to work with throughout, very communicative and accomodating, and the crew of five guys or so was extremely friendly and professional.  All in all, A Perfect Crawlspace was a pleasure to work with and we could not be happier with the results.

Energy Efficiency Auditing FAQs, answered by experts

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.
