I do all kinds of insulation for your home, from batt insulation to spray insulation, we have more than 10 years of experience offering 100 percent effective quality, we also do driwall if you need a complete service, we insulate your house completely and cover it with drywall.

"I hired Ramon and his team to do my attic insulation. He was flexible with scheduling over two days as we needed to replace ductwork for our HVAC in the attic. His prices were WAY better than anyone in Northern Virginia. He was able to come out in two days to remove all the old and dirty insulation that was thirty years old. The attic was cleaned and air gaps sealed. He came back promptly when we were for the insulation installation. Not only did they do a great job at sealing but they did a great job at spraying 18 inches of R49 Fiberglass. They were professional, timely, and cleaned up after themselves. They went above and beyond my expectations. I am so happy and would gladly recommend these guys for anyone. Five stars!!!"

"ROOFTOP DESIGN IS A HORRIBLE SCAM I would be remiss not to take the time to warn others. ROOFTOP DESIGN came as a third option for roofing. However, the initial representative ED form ROOFTOP DESIGN was very professional and thorough. The problem is, he represented a bunch of shysters. Ed’s first quote to was $35,000. After approximately three days of conversation and negotiations we were at $17,000.00 for the exact same product that they tried to sale for $35,000. Salesmen Ed was no-longer reaching out to me. Someone by the name of John called me and asked, what is it that they can do to make this deal happen. We settled at $16,500.00. Once again, $16,500 for everything discussed for the original $35,000 including a 50-year warranty that is transferable to a buyer as a good selling point. I learned through John that they fired Ed for giving customers too good of deals. I also learned through John that this company has a starting bidding price and a bottom bidding price. Ed would give the bottom price too quickly. So, they fired him. (Although John’s price was better than Ed’s). Once the job started, I received a text from the owner Yanni Avramidis. He stated that there was a third layer of roofing. He also stated that it would not be a problem and that it would take a little longer. IF THERE WAS GOING TO BE ANY ADDITIONAL CHARGES, NOW WOULD BE THE TIME TO MENTION IT. Approximately two days after the completion of the job. I had a contractor over named B. B. was there to replace the soffit beneath the location where the new roof was installed. This is when I learned and saw with my own two eyes that there was rotted or no plywood at all supporting my brand-new shingles. Mind you: per our contract, there will be an extra charge for plywood beyond the first ten free sheets. This company put my expensive shingles on top of rotted wood or no wood at all. I must admit, I was upset. However, I was cool calm and collected when I reached out to the owner Yanni Avramidis. I sent him the pictures of my findings. His explanation was that I had a 50-year warranty. My point to the owner was, if I wasn’t trying to replace my soffit it might have been months or years before this was discovered. I also said, what about the elderly man or woman that doesn’t have the ambition to check your work??? The owner of ROOFTOP DESIGN became very irate. He said, “I am from Baltimore, haven’t you heard about people from Baltimore. I will beat your a**. You are going to pay me an additional $2,800.00 for the third layer of roofing and planks/ plywood.” Since I have yet to see any new plywood, I am being charged $3,000.00 per layer of roofing to be removed. I received paperwork from ROOFTOP DESIGN, the paperwork stated that my warranty was only good for as long as I owned the property. Non-transferable: Of course, I didn’t sign it. My point is, there are people being taken advantage of everyday by bullies like ROOFTOP DESIGN."

Insulation questions, answered by experts

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.
