"They did a magnificent job of installation and the clean-up was perfect. They removed the old roof quickly, made sure the roof boards were in good shape and put the new roof on in a little over 1 day. They were careful around my plants. We even were able to get some money back for bad shingles that were used on our old roof and the best part was they did all the paperwork!! When they came over to bid the job they were very professional, had a folder with all the information put together with different roofs in the area we could look at before we made our final decision. I highly recommend them to anyone looking for a new roof!!

Energy Efficiency Auditing questions, answered by experts

Audits typically take 2-4 hours, depending on the property size and energy systems.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.
