"Absolutely amazing experience. My home radon levels were averaging 5.0 pCi/L. Two days after Edward and his team finished the mitigation job the levels went down to 0.3. Incredible result. I can’t be happier."

"David, Veronica and Maria we're pleasant to work with, Upfront and direct with all Communication. They also recommended a Clearance Testing Facility which was great, they made the Clearance appointment for me and the company called to schedule. David and his team where very profession, I've dealt with quite a few contractors and project managers and they did a fantastic job. David gave me his word that it will pass, and it did due to his expertise, knowledge and his Team. I thought his pricing was extremely fair as I have dealt with this problem in another area in the household due to lack of engineering integrity, I would definitely recommend AM:PM Restorations & Construction Inc. to friends and family. Don't hesitate to call and have them give you a quote."

"My association with Roof Rx began when I purchased an Angie's list "Big Deal"-- $69 for rain gutter cleaning and service.
The company was responsive in scheduling an appointment and also with a subsequent confirmation call and email.
The inspector (Daniel)  came as expected (November 12) and exhibited a professional manner.  After inspecting the roof and taking pictures thereof, he provided  a "summary of recommended repairs by item and showed me the photos he took. These  photos were emailed to me later the same day. I was impressed by everything that had happened --up to this point.  What I neglected to consider was that Daniel did not appear to be prepared to clean the gutters that day. I assumed the gutter cleaning would occur along with the inspection, at least that's what the Angie's List description implied.   Admittedly, I could have requested only the gutter cleaning  and even taken the time to select repairs I wanted done from the list he provided.  But, having no first hand knowledge of the roof and its features, I decided to go ahead with his recommendations, even thought I considered the costs high. We  scheduled  December 5 for the gutter cleaning and roof repair work.
On December 5 Flavio came mid morning  (10:30) and proceeded to "clean" the gutters and roof which amounted to his blowing dirt and debris from the roof and gutters all over the house, driveway, garden and adjoining properties. When Daniel came a bit later (11:05) and I expressed discomfort about the dirt, he said that the dirt/debris would be cleaned up.  The "clean up" was minimal and I continued for days to sweep up or brush dirt off of window sills, doors, etc.   Had any windows been open at the time, the "mess"would have been worse.   At no time was I told "how" they intended to clean the gutters/roof.

After the gutter "cleaning" Daniel said that they would have to come back the next day to complete the repairs.  "Normally, we have two men," he commented,  "but the weather threw everything off and only one man was available to come today; other men were needed on a bigger job. This is just a maintenance job." 
The following day (Friday) Flavio and a helper showed up unexpectedly at 10:10; I had been told that they would come in the afternoon.  The men worked for several hours on the roof.  Their application of the elastomeric  began to leave drips of white around the perimeter of the flat roof.  When I mentioned this to Flavio, he then used masking tape to curtail the seepage.
Upon my request the leak in a downspout was sealed and then the downspout was tested to make sure it was clear of debris.  I didn't think that I needed to ask them to do this, but I did.
At this point, the company believed that the job had been completed, and sent me a "thank you" e mail to that effect.  I, however, was disappointed in the quality of the service and communicated my concerns to the service manager. My e-mail to the service (sent on December 8) has been appended here:
Dear Marco,
 I have several concerns about the work that was done at my house on December 5th and 6th.
Specifically:
1)  I am not certain that all downspouts are free of debris.  Only one downspout was flushed with water; the others were not.  2) Because water was not run through the gutters, minor leaks were not identified and therefore not fixed. This was confirmed by Saturday's rain.
3) Not all gutter spikes were secured.
4)The elastomeric coating applied to the flat roof in the front of the house "seeped over" onto the metal edging leaving unattractive white stains which became worse with the rain. 
5) Regarding the garage gutters-- I expressed concern about the possibility of the downspout(s) being clogged.  Daniel indicated that the men would run water through the gutters just to check.  If there was a problem then I could decide whether I wanted to have the garage gutters serviced as well.   This was not done.
6) And, I have not received the "after" photographs as I was told I would.

Bringing this review to a close--
I did receive the "after" photos from Daniel in a timely manner.  It would have been good, though, to pair the before and after photos, side by side so one could really see what had been done.
Daniel and Flavio did return on December 21 to address my concerns. And while they did what I had assumed they would have done initially, they did so perfunctorily.  For example, when flushing the gutters with water, there was little if any concern for what the water might land on. While this may sound minor, I expected a more professional job.
And last-- I was dismayed to see that my credit card had been charged for the full amount before the job was completed.
I emailed Marco citing concerns on December 8;  The credit card was charged on December 9.  I imagine there are separate departments handling separate aspects of the business.  But, I was surprised by this action. 
Overall, the quality of the work was not commensurate with the cost. And, the aspects of professionalism , e.g. confirmation calls and emails, etc.  were not apparent in the quality of the work.

Radon Detection and Reduction questions, answered by experts

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.
