We had our basement waterproofed from the outside. Royal Works had one of the lowest quotes, but the quality of work was superb. I did some reference checks prior to the work, and all came back very positive.
The guys who did the work were from Eastern Europe, and for most of them, English was not their first language. However, they were extremely courteous, and always respectful, and somehow, we were always able to communicate without any problems. When they left in the evenings, they left the work at a point that would not cause any problems (one night, during the work period, it rained, but they had sufficiently protected the work they had done to not cause any problems).
One more point is worth mentioning. They had to waterproof below my back deck. It was too hard to get underneath, so they cut a few planks from the deck...but they replaced it well enough that it cannot be seen unless you knew and were looking for the cut. A few days after they finished the work, it again rained very hard. I noticed some water had accumulated below the deck, close to the edge of the house. I mentioned it to them, and asked if they can change the grade so that it goes away from the house. Two days later, they had come back and done that - they had removed the planks again, re-graded, and even put in a window well, and then replaced the planks...all at no additional cost.
I highly recommend these guys - they are proud of the work they do, and they stand behind the work. And, they were not focused on advertising their work either...most other waterproofing companies will make sure the company sign is planted on your front lawn from before the work starting to well after the work finishes. I think Royal Work had their sign up for one or two days out of a 5 day job. Overall, highly recommended.
