This is an outstanding company that is focused on taking care of customers and providing both quality service and a great finished product. This the job I have had AllMaster do for me and will continue to use them in the future. I previously had them do two waterproofing jobs, and they finished my basement. This job was replacing a failed sump pump. From the outset of contact them I felt they show genuine interest in meeting my needs. Julie Smith was wonderful in taking my initial call by listening to my problem and quickly identifying the best way to get me taken care of quickly. She put me in touch with their project manager, Maurice, who I’ve worked with before and he was at my house within 2 hours to assess the situation. He identified an action plan a set up a team to come out the next morning to install a new high grade sump pump with battery backup pump. Marcus and his team arrived the next morning as scheduled and completed the job in timely fashion ensuring I was satisfied. They did a great job and cleaned up after themselves. Total job was $1,800 to install high end professional grade PitBoss sump pump (not available via retail). I highly AllMaster for any job you may have that you want to ensue is completed to your satisfaction and the company fully stands behind. Again thanks to all, especially Julie for getting everything moving so quickly. Don Price

The Allmasters Team did a great job in replacing a full concrete pad, installing a larger drain, and filled the void under the steps with mudjacking to help alleviate flooding in our basement. They're an outstanding company that takes care of their customers with quality service. The team was always prompt and untiring. Always professional, I'd recommend them highly. Until we have a torrential downpour, we won't know how successful this service has been.

Last year we had problems with the concrete application of our new driveway installed by Allmaster. The Vice President, Steven Locantore personally came to our house to inspect the work. He agreed that there was an issue and that the driveway would be redone by his Company. We had to wait a long time for the weather to cooperate but Allmaster did remove the damaged concrete and replace it. We are very appreciative of the honorable way in which Mr. Locantore and his crew handled our situation. We will be looking forward to working with Allmaster in the future.

The team at Allmaster were easy to work with from to start to finish. Their work was thorough and detailed. They were very considerate of our space and made sure to leave our property looking better than when they arrived! Would definitely recommend!

Had water coming through a crack in basement wall that ran from top to bottom. Ronnie and Rory from AllMasters came in and got the job done quickly, professionally, and very effectively. Got the job done a month ago and zero water now coming through. I highly recommend them.

Allmasters did my retaining wall safely and professionally. I was very happy with the completed project. It's been over two years and the retaining wall still look amazing and new.

They were an excellent choice for the job! The demolition cleanup was superb, and they paid attention to detail when rebuilding the retaining walls and when reinstalling the low voltage LED lighting. Their pricing was competitive. I’d mist certainly use them again without hesitation!

All Master Builders was very professional and detail-oriented from beginning to end. On the day of our appointment they arrived about 30 mins. early & their presentation should be a method that many companies should follow in my opinion. Before talks about the job, history of the company or even costs, they presented all their credentials, licenses & supported kudos to assure us we chose the right company.

Very interesting procedure, it was explained carefully to me including the amount of equipment they required. They had an opening earlier than was scheduled and called to see if I wanted it. They showed up early, worked consistently, cleaned up nicely and made sure I had understood what they had done. Most of all the work and end result were amazing!!!

The guys came out on the day scheduled and worked tirelessly until the entire job was completed. After all the work was done the foreman explained everything that was done and what i needed to do for the next few days while the cement cured. VERY HAPPY with the work they did very professional and hard working.
