Get matched with top insulation pros in Ashton, MD

"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"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.

"
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."

"Everything went well. The technician, Howard Shires, called before arriving. He did a through inspection, fixed everything he found and made recommended regarding our attic's insulation requirements. He was professional and good to work with."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"Working with Sino-America General Contracting was excellent from start to finish. Our project was a complete redo of the basement - we had demo'd floors, walls, and ceiling ourselves, and hired Mason and his team to help install a custom bathroom under the stairs complete with custom shower pan, under floor heating, and tiled walls. We also had them build a small mechanical room, install insulation, redo flooring, redo drywalls, build a drywall frame around the HVAC, install new vents and ducts, and install recessed lighting. They also built a bannister for the stairs leading to the basement and installed a matching railing and bannister for the upstairs. Finally the installed new doors for the upstairs and downstairs, and moved the downstairs door to the right a few inches in order to accommodate our design. This necessitated external brickwork and they were able to match the 70 year old brick extremely well. From the initial meeting Mason was responsive and professional as we went back and forth on the design of the bathroom. The designer (whose name I sadly can't remember) did a fantastic job with clever use of space and a keen understanding of how the design will translate into real life. Experienced in AutoCAD - they provided clear and very accurate 2D renderings and beautiful 3D renderings of the finished design, including 3D renderings of the style of sinks, toilet, lights, and mirrors we wanted. The contract was well presented and explained with the scope of the project clearly identified. At no point was anything unclear. He worked with a punch list with holdback until the punch list completed. Communication of contractor's needs and schedules were well coordinated with mine so there were no surprise missed days. Worked weekends to help expedite project completion. Any issues or concerns that we had during construction were explained or addressed right away. There was an accidental error during installation of the under floor heating and Mason and his team addressed it which required removing tile, reinstalling the heating system, testing, and replacing tile. They built a good relationship of trust with excellent communication throughout The quality of the work is excellent and stands up to close scrutiny. Smooth, crisp, and even drywall and corners, including on strange angles and niches. Beautiful, uniform color application Beautiful tiling and corners. The attention to detail was also very good. As an example we turned the remaining space under the stairs into a kitty-litter area including custom trapezoidal door and externally vented bathroom fan. Despite it being in a low-traffic area, all the work in that miniature room was of the same quality - crisp corners, well-joined shoe-moulding, and nicely painted edges. I recommend Sino-American Construction without hesitation."

"Overall it went well except I didn't get the other estimates I requested for insulation and gutters. This was not the low bid but they have done several cedar roofs in the area and have a good reputation. The end result looks really good.

"They actually talked me out of hiring them as the amount they would have to charge would be more than it was worth. He even told me what insulation to buy."
