"Debbie, the AC&R salesperson, was very knowledgeable and confident. They were the 2nd quote I got for work and came in even lower than I expected (which gave me pause as a low bid is a red flag). But true to her word, they did the work professionally (mostly...see below) and promptly. While I had another company do the energy audit for the Pepco rebate, AC&R took over the work, did the blown fiberglass one day and the spray foam the next.



For the blown fiberglass in the attics above our additions, they added spray foam (from a can) around any gaps per the contract and foam board baffles at the soffits. The installer noted that all our soffits were blocked and the batting insulation was too wide for the rafter channels, so he leveled it out as best he could to ensure an even coating of blown insulation. At the end, he sealed up the gaps between the attic and our to-be-finished upstairs (cape cod style, so all one room).



For the spray foam insulation, the team came in the next day, and I had to be out of the house due to fumes. I did come back around noon as they expected to be done well before then. They didn't know I came in and I went to the back of the house to watch TV on my work break. The one annoyance was during their cleanup, one of the installers came down into our kitchen and then saw me. He said he was looking for a vacuum cleaner to clean the stairs. I told him don't worry about the carpet as it was getting pulled up, but this was the one piece of unprofessionalism I noted above. Contractors should NEVER use the homeowner's property; they should bring their own tools, including vacuums!



While the spray foam can get very messy, they kept the splatter mostly contained to inside the crawlspace, not the finished flooring. However, I was surprised that they didn't tape off the outlet covers or light switched. since the particles are so small, we're going to have to replace the switches/receptacles at our cost. Also, there was a storm door screen that wasn't covered and now needs cleaned. Basically, I think they should have taken more care in covering the very few items we left upstairs and the outlets/switches.



They didn't spray around the window frames (large gaps where window weights used to be) because the open cell foam would expand too much. If I wasn't there, I think they would have just left, but it was clear in our contract discussions they needed to insulate those spaces too. They used a few cans of "Good Stuff" equivalent, but didn't fill in the gaps entirely. It did the job well enough, but it's a ding against them as I expected more preparation.



Lastly, I thought that AC&R would walk me through all the scheduling and final "test out" (for the Pepco rebate), but I had to contact them and schedule with someone different each time. They were always prompt, but I expect the experts to know to do this for/with me rather than expect me to know the process. I go through it once in a lifetime while they do it weekly.



While the end of the review sounds more negative than positive, I would definitely recommend AC&R out to others as they're priced right, they have been in business for over a century, and like any contractor, you just need to follow up to be sure everything is done to your satisfaction.

"The initial energy audit took ~4 hours and the technician, Andre was punctual, professional and sat down with me to explain the process at the beginning and end of the audit.
I then met with a manager the following week to review the results of the audit and the proposed services. I was also informed of the state energy rebate and the availability of a 0% interest rate loan to have the work performed. I qualified for a $2,000 rebate and a $5,000 loan. I elected to have all proposed services performed.
The loan process was automated, efficient and the scheduling process was efficient.
Mike and Devin arrived on time, were professional and considerate of my home as the spent 3 days insulating my garage ceiling, attic and crawl space. Baffles were installed in the rafters to ensure proper ventilation of the attic, whilst all areas contacting the inside of my home ("the envelope") were sealed and insulated to code(and then some), including foam and blown in insulation. In the garage ceiling (below the living room), the 10" space only had 6" of insulation. Holes were drilled in the drywall and insul ation was blown in. The holes were then patched and spackled (not sanded). All seams between the cinder block walls and drywall were sealed with foam and the exposed pipes were wrapped. 
A manager came out the following week to inspect the work performed. He noted several punchlist items and deferred the blower door test until these items were completed. This was scheduled promptly and completed achieving the targeted airflow reduction in the proposal. This report is being sent to the state to verify the rebate and my home may be selected for a state audit. 
Overall I am very pleased with the work performed. My home holds the heat much more effectively. I highly recommend the Mark Group.

Company personnel scheduled to do the work on a semi holiday and they arrived on time/when they said they woudl.  They were very attentive to doing a good job - they lined the floor with plastic; they vacuumed up excess insulation).  They even phoned up days after completing the project to inform us that we might be able to take advantage of a tax benefit.  We would definitely recommend this company."

"We had a horrendous situation with a basement floor installation that went wrong leaving our house full of fumes, and a week later we discovered our basement was contaminated by asbestos in the process.  When we called Bill and Contractors Unlimited, they were extremely responsive.  Although other companies gave us bids, Bill was able to work his schedule to fit us in weeks sooner than the others.  Although the cost was a bit more, that saved us money because we were displaced and could not even go into our house because of the fumes.  CU set up negative air machines to replace the air, they followed asbestos abatement laws, they cleaned every item that could be salvaged in our house.  They even saved more than we thought which really reduced our overall expense.  Bill and his team were extremely professional, friendly, helpful, and really went out of their way to ease our stress from this situation.  At the end of their process, Bill arranged for a air quality inspection which we happily passed - able to return home.  I would gladly recommend Contractors Unlimited for asbestos abatement.  I just wish we had called them before the floor guys  created such a disaster.  Thank you Bill!

"I called Evergreen Electric and setup an appointment for the next day to perform what I figured would be a couple small jobs and to receive an estimate to run cable into new rooms. The original appointment was delayed because of a power outage on another job, but speaking to Josh on the phone, he was willing to come by as soon as he was finished even though it would have been well into the evening. I told him the following day would work fine and we rescheduled the appointment.
Josh arrived the next day and examined our situation. Our house is nearly 40 years old and it turns out the problems were much deeper than I thought. Josh crawled into the attic and rewired the junction boxes that were not just loose but had previously been wired incorrectly. He also spent well over an hour attempting to diagnose why our breaker was tripping without much of a load on it. He was very thorough in his troubleshooting. He replaced the breaker with a higher amp version and the problem is fixed, but he also indicated there is likely more faulty wiring running through the attic buried under the insulation and someone should come back to assess the entire electrical system.
Josh was very courteous and professional and answered all of my questions. After spending about 2.5 hours with us, I was expecting a large bill. I was very pleased when he told me he would only be billing me for one hour.
About 30 minutes after he left, we noticed that a light in the hallway would not turn off. I called to report it and Evergreen responded immediately. Josh came back right away and fixed the problem. He even replaced the light switch free of charge. It is nice to see a company that stands by its work and acts so quickly when something is wrong.
I would highly recommend Evergreen Electric. They are prompt, thorough, and stand by their work.

AMS got my permit for me and was able to closely match my vinyl siding and roof shingles. It took a few days but one was because of rain. They also replaced my front gutters to fit in with my new portico.

The new portico blends well with the house and AMS took care that the new materials they used went well with the old materials. They cleaned up every day and after the job was finished. My old portico slanted down and dripped rain and snow on my front steps. The new one is a Gable roof and makes a big difference on snow days.

AMS handled al the Montgomery County inspections and the final approval.

Drywall Insulation FAQs, answered by experts

Common causes include water leaks, settling, and impact. Address underlying issues to prevent recurring damage.

White walls are the toughest color to keep clean and maintain, as they’re extremely unforgiving when it comes to dirt, splatters, dust, and smudges. Still, many people look past their high-maintenance requirements because they lighten and modernize a space beautifully. If you’re opting for white walls, it’s especially important to keep up with regular cleanings, so they stay pristine.

Yes, cabinets are installed over drywall. The drywall must be in good condition, and you must ensure that the wall can handle the weight of the cabinets. Secure the cabinets to studs and use proper anchoring devices, like toggle bolts.

You can repair plaster ceilings yourself after the cause of the ceiling damage has been addressed. However, the repair can easily take 5 hours and can be slightly challenging for those without previous experience. If you do decide to flex your DIY muscle, have a helper to help hold the ladder and pass you the tools for safety purposes.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly.
