G&J waterproofing is working on a second property for us now. At no point did I ever feel like…read moreHarry or Katie were dishonest. The work their company did solved our water problem and yes sometimes its hard to get guys and sometimes they have multiple projects going on and they are not exactly sure when they will be there but at the end of the week the job is done correctly and at a reasonable price. They try their best and they communicate when you send them a email. So if you have to throw away a bag of cement left behind , well big deal just throw it away. For the price its a good value and it definately solved our water problem just be a little patient and understanding.

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.

Eventually, he looked at the first project, 9 steps that needed some cracks repaired. Said they dont repair anything, only level. I had 4 jobs total, 2 sidewalks to level and a patio pad. We never got to other jobs, he was so rude and disinterested, that I asked him to leave.

Totally respectable workers and employees from start to finish! I feel like I got a new driveway for the fraction of the price of removing the old concrete and pouring new slab's. They used a pressurized slurry of limestone injected through the concrete to level the slabs across my entire driveway. The diamond ground all of the joints between my house and the driveway and between all of the slabs and sealed it perfectly! The before and after is incredible. Thrilled with the work and will recommend them to anyone who needs to have concrete leveling done!

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.
