"Thank you James Im, Antonio and crew for an amazing experience and a job well done! It is rare these days to find a home improvement company that you can trust from beginning to end. AHC staff and representatives ensured that every detail from estimates, to coordinating delivery of materials and quality control of installation was performed to the highest standards and exactly on time. James and Antonio/crew were attentive to our every question and concern, and in the end made the experience with AHC a memorable one worthy of the highest level recommendation. Bottom line: If you choose any other roof replacement contractor - you will be making a mistake!"

"There was a problem initially with the radiant barrier installation - the first crew of two were installing 30" wide rolls lengthwise along the roof end to end  instead of from ridge to eave as the manufacturer recommends and made a couple of other minor mistakes which were easily corrected. After talking to the manufacturer, the sales rep offered to take out what had been installed and re-install according to spec or continue as already done with sealing of all seams and a discount on the job. Done this way, the foil would not have the insulation properties per spec but would provide the radiant barrier I desired. I chose the letter option and the barrier work was continued by another crew on the 2nd day. On the 3rd day the crew finished up with the barrier then blew in the installation.

With the exception of the initial problem, the work was done neatly and professionally by courteous workmen who cleaned up completely after the job was done.

Same quality and company, NEW NAME!!!! Yep we've upgraded our branding to better reflect out company goals. As always, quality products are essential for success, but without certified and trained technicians installing everything to the exact specifications for greatest success, your home wouldn't get the best results. That's why we do things right - every time. Our excellent products come with extended/lifetime warranties INCLUDED - there will never be an upcharge for a warranty. The adage "you get what you pay for" is 100% true for Insulation Geniuses. We'd rather explain the investment up front rather than trying to explain quality for the next 20 years...

Another Happy Homeowner!

"We contacted the Mark Group for a Home Energy Assessment because of coldness in our first floor living area and basement. Gordon performed the assessment and provided recommendations and an estimate to energy seal our basement with spray foam insulation. He assured us that having the work done would substantially decrease air loss, and as a result, the temperature of our first floor and basement would become so warm, we would be wearing short sleeves instead of sweatshirts. Gordon offered us a financial incentive to provide a deposit the day of estimate, something we rarely do. He also pointed out that the crew were professionals, and the insulation would not be sloppily applied, as was the case with a previous attempt by my husband around the circuit box. Gordon added that his crew would conduct a health/safety inspection of our existing CO detectors and install a new CO detector, if needed.   
Subsequently we had the work done by 2 men who arrived promptly on the scheduled day. They took care to protect our carpet and furniture from debris, and removed and disposed of the old insulation before applying the spray foam. They did not provide any feedback on the status of our existing CO detectors but left a new one at the end of the day. Before leaving, they requested an immediate evaluation for Angie's List.  Upon a brief inspection, everything appeared to be satisfactory to my husband, and he complied by completing the form and giving all A grades.  At the time, the front door had been open for 2-3 hours; as this was necessary for proper performance of a blower door test, the house was understandably cold immediately following. 
However, the next day my husband and I both noticed no difference in the temperature of the basement or first floor. Upon closer inspection, my husband observed gaps in the insulation where air flow was still evident. In our opinion, if the old dirt and debris had been vacuumed after removal of the old insulation, the spray would have adhered better, but they did not make the extra effort to do this. In addition, we saw an overall lack of uniformity in the application of the insulation. In some areas the foam was evenly applied, but more often than not, there were several areas where the foam did not completely fill the space or overflowed on to the cinder-block wall.  He promptly contacted the Mark Group and Gordon informed him that someone would contact us to schedule a return visit.  I subsequently emailed Gordon photos of the insulation and requested another thermal camera analysis. Additionally, after further inspection when moving items back into place, there was significant debris on the floor, as well as other areas of the basement that took several hours to clean up.
Approximately 5 days later, Pat came out to inspect the work done and brought the thermal camera. He performed the thermal analysis in the basement and filled in the gaps mentioned,  but explained it was difficult to evenly apply the insulation given the nature of the product and application. Also, he pointed out that due to the structure of our home, it was impossible to substantially improve the temperature in the basement and first floor without having significant structural renovations. While we appreciated Pat's honesty, we felt like Gordon made empty promises and overestimated the benefits of the air sealing.  
This was one of the few times, my husband and I agreed to have work done at the time of estimate, mainly because of the majority of highly favorable reviews,  persuasive statements regarding comfort level, and financial incentive.  Looking back, however, after re-reading ?F? review, I can relate to the homeowner's frustration and regret making the decision without further questioning.

FAQs for batt, rolled or reflective insulation install or upgrade projects in Dundalk, MD

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
