The cracks in the walls just kept growing and we knew that we had to do something to prevent more damage. The representative, sales person Brian, who came to meet with us for an estimate was very reassuring and informative about what would be done. He said that it was amazing no jacks had been put in previously, the distance between the beams was much too far and the wooden joists were cracking. He provided a comprehensive proposal and was ready to talk with us on the phone before we had the work scheduled to be completed. This was very helpful to calm our worries. The work that was done was, fast, efficient and we are very happy with the result. Chis was our foreman, many thanks to him! I recommend this company very highly. It's hard to trust a company that you might find on the internet. I think that we were very lucky that we were able to find Keystone. We improved the value of our property. Friends and family were uncomfortable with the pricing and it was hard on our budget but the quality and timeliness that Keystone provided was definitely worth what we paid for in my opinion.

Groundworks(formerly Baker's Waterproofing) installed an air purification system a few years ago to…read moreremove moisture from the air in my finished basement. It works great and anytime a tune-up is needed, their service is fast and professional. Today service manager Lee Cochrane came out for a request to relocate the unit to the furnace room where it would be less prominent, basically out of sight. What I thought would be a long and costly solution, Lee moved the unit in minutes connecting to condensation pump line to the one on the furnace. No need to drill a new hole to the outside. I'm very impressed with this company and would recommend them to friends and family.

It's amazing the guy actually walked away like the job was finished and done properly. It's not a good sign when 4 neighbors ask if she did the work herself. And this thief advertises in the church bulletin! No doubt to rip off the senior citizens. Had two corners to patch, which look worse than they did before he touched them. Didn't brush anything to blend in to existing concrete, just half assed the whole thing and stole the money. Clearly this piece of garbage has no conscienc and no issue with stealing money. Absolute joke of a job. Terrible. If you're thinking about calling this guy, save your money and just have a toddler do it. should be zero stars.

G&J put a French drain in my home less than two years ago. First off the workmanship was shoddy…read more The interior discharge pipe is just hanging out of the wall with the cement patch job on the interior side of the hole going to the outside being the only thing holding it in place. The cement patch work, interior and exterior, looks like it was done by a two year old. The "kids" who actually did the work were a couple of non-English speakers and someone who looked to be younger than my grandson. Less than two years later there are large cracks in the exterior discharge pipe. This causes the water that collects in the sump pit to just swirl around and go nowhere. This happens to coincide with a period of recurring rain, often heavy, over the past week. Of course the problem happened over the weekend. I emailed them about the problem on Sunday. To their credit, they did reply to the email. On Tuesday they emailed that someone would come between 10-2 PM the forthcoming Friday. In the meantime my wife and I spent the week (including in the middle of the night) bailing water out of the sump pit. Friday comes and I have to take the day off from work to be here when they come. But guess what? Nobody from G&J showed up and nobody from G&J even called. Instead they emailed me at 1:30 in the afternoon to say that most of their crews had called off because of a big storm the previous night (storm???). I blame myself for hiring these people in the first place. Don't make the same mistake. Stay away from G&J Waterproofing.

I had scheduled an appointment. On day of appointment, 45 minutes beforehand I get a text to…read moreconfirm. Half an hour before appointment I get a phone message to confirm. Both times I was on the road driving home for scheduled appointment and could not respond. I got home 15 minutes before appointment and confirmed by text and returned phone call of technician, Chris. Chris was snippy and seemed to think sending me a request for confirmation only on day of appointment and only within 45 minutes was satisfactory and my not responding right away had him snippily ask if i was still interested because now because i didn't respond 45 minutes before appt he can't be there til 1.5 hours later than scheduled appt. What the hell? In my experience confirmations are NEVER last minute. They could easily have confirmed yesterday. Since I am on time for appointment, they want to find a cop-out excuse to be late? No, thanks. Poor attitude, late confirmation request, and no on-time appointment trying to blame me, the client? Hell no. Plenty other businesses. Oh, and, to boot, Chris I found out, is the owner. Nice... Update: to the owner Roberta's ugly response?, I say tell the truth. Trying to reach me for a confirmation 45 minutes before the appointment as the only time you try to confirm and expecting an immediate response? Why not just assume it IS a go at that point since the tech should be on his way by then. And Roberta saying in response that tech was going to only be 15 minutes late? Not true. Chris said he was going to be 1.5 hours late. Instead if 3pm he was going to be closer to 4:30. So the call for confirmation wasn't even to confirm, just to say he would be late, very late after first admonishing me for not being available for a very late confirmation request 45 minutes before scheduled appointment. Why, oh why would they begin to presume that a day-of confirmation 45 minutes before appointment being answered within a half hour AND before appointment time is unacceptable to them? What planet do they live on? Again, other businesses exist.
