After 40 years, our insulation was falling off. We also had (they discovered) squirrel damage…read more C.I. had a team of extremely hard-working folks who removed all the old stuff, repaired the squirrel damage, and then sprayed foam throughout our attic. The work was noisy and their workday was long. But worth it. The price was not inexpensive, but we believe for the number of workers, and the extent of the work, the price was fair. It's not something I want to be good at.

After accepting the proposal, they gave us an estimated arrival date of 2 weeks or less, which gave us time to prepare the area. Just like clockwork, 2 fellas show up; on time and with a very professional set up; nice new truck and matching trailer. They reviewed the scope of work with us and went right to it; one guy spraying and the other manning the high tech equipment, making sure the one spraying had plenty of hose and ensuring there would be no overspray landing on anything that it shouldn't. Once the job was complete, they reviewed everything with us to make sure we were happy and satisfied, which we were. They did a great job that looks amazing. We highly recommend them and would definitely use them again.

With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are. We are very happy with our windows. Almost as happy as we are with the people who got them into our home.

After all, it is our home and we want to make certain we get the best products, expert craftsmanship, and clean installation that is issue free. The crew was on time, professional, communicated process well and worked hard to do a good job the correct way. The crew lead was Jeff and he was super professional and came across as very honest. They cleaned throughout the entire process, installed all products that fit perfectly with expert skills. They did a thorough job at insulation replacement windows and the finish caulk job was immaculate. The look from the curb is stunning and I can notice how well the windows are performing as it seems the air is running less in just the week we had them. We love our new Okna 800 windows and Eric and team killed it!

Spray foam insulation installation on a new construction house. When dealing with the owner Tony I…read moregot that used car vibe, I knew I should hire a reputable company but I never learn. His company named Four State Insulation in Kearneysville WV was hired to come out and install on the exterior of the house, spray foam insulation between the floors for sound proofing. What I received was a company named A&A insulation out of Upper Marlboro MD. A&A insulation sprayed most of the exterior walls off the house. I take writing a negative review very seriously and have probably only written a couple over the past 30 years. If you get a price from this company you need to add at least a thousand dollars for legal fees to deal with them plus the extra money to hire a reputable company to come do the work.

We had the provide insulation in the attic of our house and were told afterwards that they would follow up with us to make sure the other rooms in the house were taken care of. Once they completed the larger more expensive project in the attic they stopped answering my calls, texts, and emails. They had someone come over to the house to check the other rooms had them pull up our floor boards to take a look then never followed up to actually provide the service. I have called both my point of contact and the office multiple times with no response. As a result I am having to go with another company to have the rest of our work done which is extremely unfortunate.
