Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"Needed my attic insulated with winter approaching, and after taking a lot of quotes decided to go with E&A. They were professional, polite, and knowledgeable. I called a few times ahead of hiring them and they took the time to work through the scope of the project. I never felt pressured to do anything a specific way like a lot of other companies do with their salespeople. Instead they helped me understand my options. After hiring them, they showed up when they said they would and worked very hard until the job was done. I have a large attic and the two of them worked tirelessly. They also added a catwalk to get to my air handler and cleaned out old insulation. They did a great job and we could immediately feel the difference in the house. Overall, it was a great experience. Definitely hire them."

Basement Waterproofing questions, answered by experts

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Water damage to a foundation often starts as a slow leak or water vapor problem that worsens over the course of months or even years. The speed at which foundation leaks worsen depends on a few factors, including your climate and location, the soil composition around your home, the foundation drainage system you have in place, if any, and the type of foundation you have. Even if you have a minor issue that’s slow to develop, it’s best to have a professional address the issue immediately.
