I hired Baker's Waterproofing at recommendation of a recently hired plumbing contractor after their work revealed a leak coming through my foundation. I called Baker's and they sent somebody out for an initial inspection of my basement and garage. It was ultimately uncovered that my foundation was built of cinderblocks and was not only leaking water from the steep hill behind my home whenever it rained or whenever snow melted, but also that groundwater was welling up and through it from the ground below. Baker's scheduled a time that worked for both their workers and my time, and sent out Victor and Miguel to get a full waterproofing, french drain, and pump installation with backup system installation completed. Their work quality, work ethic, and determination to keep timeliness blew me away. Despite running into several complications and delays that were through no fault of their own, not to mention inclement weather on one of the scheduled days of work (heavy snowfall), they managed to work with their small crew to get all of the work done in about a week's total time. It only took them two days of work to complete a full job along nearly the entire basement wall, the whole back garage wall, and one entire side wall of the garage. On top of this, from start to finish of this project with Baker's Waterproofing, every person I spoke to and worked with was extremely professional, courteous, and explained anything I needed elaboration on clearly and concisely; and their pricing was not only competitive, but extremely reasonable for the quality and quantity of work they did. I cannot recommend Baker's Waterproofing enough; they are worth every minute and every penny. Special thanks to Victor and Miguel. If I ever need anything Baker's Waterproofing can do again, I am definitely asking for them by name.

This review is for any single, female, homeowner that needs work done and are looking for an honest company. Trust Bakers. I had Bob come to give me an estimate on my cracked, sunken patio, he let me know they could try to do it but it wouldn't be pretty and I may not get the results I wanted. I wanted to try anyway. We booked. Bob called and said I was assigned a foreman named Hayden and he thought that was the best foreman for the job. The day of my appointment arrived, bad weather hit. They went out of their way to reschedule me for the weekend. No worries. The day came. Hayden arrived and let me know if he did the job I would be wasting my money and that I should just put the funds towards getting a new patio….in a nice way. When Bob did his inspection my patio was decorated with chairs, rugs, Halloween decorations and things. I had it emptied for the job. So, he could not accurately assess. Not his fault! I'm very happy with the services I ended up not receiving from this company due to their honesty and ethics. Customer service was also great. Communication was great. If I ever have a need in the future (I probably will, my house is 107yrs old) I will not hesitate to contact Bakers Waterproofing. You shouldn't hesitate to contact them either!

The gentlemen (Daylan, Nick and Mike) that competed the work were terrific. They kept me well informed and did an excellent job. They found the source of leak that was different than what I originally thought and explained the issue to my plumber. They left the area cleaned and removed all debris. I would highly recommend them. They explained how the sump pump worked as well as the backup battery and what I should do if there was an issue. The gentleman (Bob Massaro) that explained the services that I needed, and price did an excellent job showing me the areas of issues, and how the Baker's would fix the issues. He answered all my questions and was available. Since we ran into an unexpected issue, he came to my house during the work, which I really appreciated. I would highly recommend Baker's Waterproofing.

The technician, Bill, just finished the first annual inspection of the installation that was completed a year ago and I wanted to add my 2 cents worth to the many positive reviews already up. From estimate to this first inspection my experience with Bakers Waterproofing has truly been 5 star! At installation the technician felt that changing to wall anchors would be a better choice and, after some discussion with the company, was able to do the job with only a small adjustment in the final price. Since that time, each time I go into the basement, I am impressed with the appearance of the work and the knowledge that that wall is secure! Add to that the personable and caring technicians that do the follow-up work and I am confident in recommending Baker Waterproofing to anyone that asks!

We can’t recommend Groundworks enough for sump pump installation. They were professional, affordable, and extremely mindful of our budget —they even helped us save money by finding a way to work around our existing hot water tank. The level of professionalism and hospitality we received was rare; everyone who worked on our project was personable and committed to our satisfaction. Their knowledge, attention to detail and timely completion were impressive, but their hospitality and integrity is reason enough to hire them. If you're looking for quality work and a team that treats you like family, Groundworks is the way to go!

Wendell W. came to look at my water issue. He did an excellent job of explaining what needed to be done to correct it. Cale, Shay and Joel came to start the waterproofing project and discovered that the back wall of my house was bowing. Martin came to evaluate what needed done. The team stabilized my back wall and also did the interior work to fix the water issue. Installing the stabilizing bars wasn't easy due to so much rock. The guys worked very hard (they had to rent another machine) and got the job done in one day!! The guys cleaned up the inside and left the outside looking great!! I look forward to seeing the system do its job. I would recommend Bakers Waterproofing! Thanks

From the first inspection and estimate, through my numerous questions regarding the wall anchor installation and foundation stability, and through project completion, Baker’s provided the most outstanding and professional service I’ve received in any home project I have had undertaken. Brad did a brilliant job offering initial advice concerning repair options and financing. Afterward, Charlie and his team did outstanding work in installation, respecting our property while improving it immensely. Their patience, attention to detail, and courtesy is unparalleled in my experience.
