"I was impressed with the quality and skill of the crew, they knew exactly what to do and the result was excellent. I was extremely impressed with the quality of the insulation, and feel much more comfortable with my home! The foreman was excellent, very skilled, and the turn out was outstanding!"

"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."
Owens Corning ProPink R-49 Blown-In Insulation. Our most popular product
These vents help your attic circulate air. With attics reaching over 120 degrees in the summer these are very important. They prevent mold and increase the lifetime of your insulation. Most other contractors miss installing these.
Look at the difference! Our foam is fire-rated which allows us to air seal around penetrations that contractors never could before.
Most homes have penetrations all over there attic. Imagine trying to blow up a balloon with a bunch of holes. It will never fill up. Now imagine trying to blow up your house with air conditioning and heating with a bunch of holes in the attic. It will never fill up.
Recessed can lights are notorious for leaking air. Recessed can light covers help with air-sealing your living space and prevent fires.

"Atlas Home Energy Solution performed an energy audit for my home, followed by various insulation and weather-proofing tasks. Three other companies gave me estimates much higher for a work smaller in scope. Atlas estimate was lower for a more extensive work, and when combined with the rebate from BGE, turned out to be a highly reasonable deal. The employees were pleasant, courteous, and performed every task to perfection. I highly recommend them for any home energy issues"

"I would just like to thank this company for the work they did in my home! Iâ m very late writing my review but I wanted to see how different my home felt since having this service. Complete Home Solutions serviced my house on November 20, 2020, The crew consisted of Brad, Jason, Aaron and John B. There was another individual who did my drywall work, but I didnâ t get his name. There are no words to describe how much I appreciate your professionalism, knowledge, experience, cleanliness, kindness...etc. You guys did such a wonderful job! Since getting insulation put in my sonâ s room, I can feel the difference, a huge difference!! Also, I would like to thank Noah for the first initial visit and explaining to me in detail about the difference in the products. If youâ re looking for a company to provide service to your home, thereâ s no need to look any further! Iâ m looking forward to hiring them again, for my crawl space."

"This was the second time we hired ROI Construction LLC to work on our home and they did an excellent job both times. Originally our roof was replaced and ROI did a fantastic job, going above and beyond in making sure every detail was perfect. Recently we had the roof and skylights of an addition replaced. In both instances ROI charged less than the competitors and the workmanship was high grade. I highly recommend this company."

"The team was professional, worked quickly, and the install went smoothly. The only negative, which may not affect everyone, is when they went to open the knee walls to install the insulation. They did not cover any of my furniture or personal items. I have now spent the last week trying to clean all the dry wall dust off of and inside my electronics, clothes, walls, etc. This has truly been a nightmare. Additionally, the salesman said they would replace the drywall, tape and mud the seams, and I would only need to paint. Not totally true. One coat of mud is not sufficient and it's wet when they leave so they didn't sand it. A minimum of two coats with sanding in between and at the end is required which means I would have had to buy the supplies and do this myself or hire someone (63 yr old female and I had the supplies from a previous job and know how but didn't plan on it or want to). I'm more than two weeks later and still trying to finish this task between working and cleaning drywall dust. All other debris and materials were cleaned up to my full satisfaction. I would hire this company again and I do recommend them but make sure you yourself cover everything within range of falling dust and know the "only have to paint" is far from the truth. Good job otherwise and looking forward to the summer heat to test this investment."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Ellicott City, 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.
