"I'm proud to hear my son, Robert Wolfrum, is working for Perma-Seal. I first used Perma-Seal in the 80's for a foundation crack repair in our South Holland, IL home and then again at our Tinley Park, IL home. Both experiences were memorable and professional and fixed our basement water problems. It is good to know that my son is working for a reputable company that has been doing quality work for decades. I was surprised to hear that they do insulation and concrete leveling."

"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"Overall the job went very well.  There was a problem that was discovered in reparation for the demolition of the large
patio slab that Professional Concrete moved quickly to overcome.  The slab to be demolished had cedar 4ftx4ft posts laid in the concrete as an artistic grid.  There was concrete under the posts that was thought to be 2in thick (common practice), for a total thickness of 6in of concrete that would have to be removed.  In reality there was a total thickness of 8in and re-bar.  Professional Concrete provided a revised cost then and there, which I approved and they went off the get heavier demo equipment.  Demolition was completed that first day.  Framing was done two days later after a rain delay.  The next gravel was laid.  The concrete was to be poured on two separated days.  The steps and small pad one day and the large slab the next.  On the first pour day Mr. Martinez and his crew came by all set to pour and the weather was not optimum so the pours were put off until the following Monday.  He did not want to rush and have the concrete crack in the future.  I was in total agreement.  On that Monday the weather just right and the two days of pours went off smoothly.  Once the concrete set properly Professional Concrete returned shortly to cut the crack arrests.  What remains to be done is application of the sealant and top soil to fill in by the forms and the ruts made in the lawn by the equipment. 
Throughout, Mr. Martinez and his crew were courteous, neat and efficient and explained each phase of work. 
I would recommend them and use them again.

"Rivera Concrete Paving's $8,500 bid became $11,000. Owner Magdiel Rivera adds charges after you're committed and doesn't follow through after payment. Cost increases: I mentioned roots upfront - he said equipment could handle it, then charged $450. Said grading unnecessary, then created false urgency claiming we HAD to grade before concrete. Later said could grade after. Added $1,800. Crew broke drainage pipes, charged me $250. Couldn't move AC condenser despite my asking during estimate. Payment tactics: Said pay "when satisfied." Then requested half early, then full payment before done. When I said work incomplete, he asked "Don't you trust me?" then broke promises. Broken promises: Walkway cured wrong, no follow-up. $1,800 grading included 3-month landscaping - no communication. Promised debris cleanup, later said not responsible. Damaged 4-month fence, couldn't repair properly, paid $300 after pressure. Dismisses costs at estimate, adds them later. Makes promises, then excuses."
