"Debbie showed up on time and seemed knowledgable about insulation. However she had a hard time answering my questions because she was overly fixated on price. That's not necessarily a bad thing but it got in the way of me really understanding the answers. When the quote came in it was very resonable but when i emailed with a follow-up question concerning warranties, the lack of record on Angies List (despite being in biz for 100+ yrs) and a sub-contractor she was going to use for an exhaust ventilation, she wouldn't put some of the answers in writing until after I committed to using her company. After reviewing all of the quotes we received we finally decided to take a leap of faith because she seemed knowledgable and the quote was fair. i emailed saying we wanted to move forward and asked if i could i now get the informatoin i requested in writing. Unfortunately it's now been 5 days so we are moving in another direction. I bet the company does quality work but it won't be with us.

"They pointed out areas of air loss that needed to be covered or blocked and advised  more attic insulation which service they will provide. Their price offer seems reasonable.  I'm still crunching numbers.

"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.

"We have the BGE Home protection program, so we have them come out in Fall to do a check-up on the heating system, and in the Spring to check-up on the A/C. They are always prompt, pleasant and professional. In the past we have had them repair the system and we area always happy with their work. The protection plan is well worth it - we had a water heater die and it was great that we could call BGE and have the problem fixed without having to pay thousands of dollars.

"My home was very drafty.  During the consultation I was told that by insulating my heating and AC bills could be reduced by 40%.  This past winter was not cold enough to compare, but in the summer my air ran constantly and my bills were not reduced even 20%.  My interior walls have nail pops everywhere.

"The busy office staff was friendly and professional. My calls and emails were promptly returned.
(We did have a minor communication snafu, which we were able to resolve.)
Our estimate was scheduled, and Jack came to our home to provide it.
He answered all our questions and left a detailed proposal. Once we signed and returned the proposal, the 2-day work was scheduled for 2 weeks out. A snowstorm delayed the start date one more week.

Day 1 -
Jason and Justin arrived on time. The first job was insulating some of our basement ceiling copper pipes to help them resist freezing. (One pipe had frozen and burst in February's extended cold snap. It was repaired by a plumber, thus the drywall repair.)
The second job was replacing the drywall.
It was suggested that I remove the stairwell art so they could bring in the sheet of drywall without harming the art.
After the drywall was done, they removed the debris.

After hearing that I was concerned about drywall dust that could result from tomorrow's sanding, Jason gave me a suggestion to minimize the amount of dust: turn off the heat during sanding, and open the windows.

Day 2 -
The workers arrived as promised.
The office called to make sure I was pleased so far, and that the work was going as planned.
The sanding of the drywall, of course, generated dust, but they considerately used a vacuum during sanding, which, combined with the open windows, greatly reduced the amount of dust in the air.
(I was understandably elated that this was the first drywall repair where I experienced no respiratory distress!)
There's another step before the actual painting begins (perhaps "sealing" the drywall?)
The ceiling was painted with paint we provided.

Jason and Justin cleaned up. The job was completed on time, beautifully done.

I would definitely hire Home Pro Roofing and Remodeling again: from the owner, to the office, to the contractors, it's clear that they care
about their customers' satisfsction.

Insulation questions, answered by experts

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.
